So if your hard drive is full and you want to quickly clear up some space there are plenty of places to look to clear out some files that you probably don't need. First let's start off in the Media Apps. In the TV App if you go under Library to either Movies or TV Shows you'll see a list of videos that you have. Now a lot of these may not be downloaded. If you move your pointer over one you'll see a little Cloud icon indicating that you own this movie but you don't have it currently downloaded to this Mac. So it's not taking up space. But if you don't see this here, that means the movie is using space on your drive and you can click here. Instead of Download you'll see the option to remove it. Better yet there's an easier way to see these. You can go to what I call the Storage Manager. We're going to use that a lot here.  
Go to the Apple Menu and About This Mac. Then you click on Storage at the top and click on Manage. Now you have some easy access to get rid of some things here on the left. So let's go to TV. This is going to show you a list of everything you've got downloaded. You click here to sort it by size and you can select one to delete it. It's a really easy way to do it. You don't even have to open the TV App. 
So next let's go to Podcasts. In Podcasts if you go to Downloaded on the left it's going to show you all of the podcasts you currently have downloaded and you can click here on the three dots and remove downloads. But like with TV you can go to the Storage Manager here, the same way, but instead go to Podcasts. Now you can see all of your Podcasts here. You can sort by size and you could put the largest on top. Then you could select one, click Delete to delete it. You could also Shift Click to select a range or Command A to select All and delete and clear off a lot of space. Of course it's easy to go back into the Podcast App and redownload podcasts. Just like you can reload TV shows and movies that you purchased later on. You don't have to store them on your Mac. 
So the third place to look is Books. In Books there's no downloaded section here. But if you go to Library, All you'll notice some of the books have a Cloud icon there meaning that you don't currently have them downloaded and other do not. You can click and remove like that. But the Storage Manager also has a Books here on the left. You can see which ones that you've got. You can Sort them. You can select one or many and Delete. Now let's look at some other places. 
GarageBand has to store a lot of audio data on your drive. Now if you rarely ever used GarageBand or maybe you just used it once to play around with it and right now it's not important. If you need to clear up some space you could do so by getting rid of a lot of GarageBand data. So go to the Computer Level in the Finder. Then go in your hard drive down to Library and in there are a few places here where you find GarageBand content. First let's look in Application Support. Under that I can find GarageBand. I can do Command i and see that this is a pretty sizable folder here. So if I'm not going to use GarageBand I can just delete that folder. But a lot of GarageBand stuff is actually filed under Logic. Logic is another app that Apple has that's the more pro level music app. So you could find those here and you could see that this one could be even bigger. So if you don't have Logic and you're not planning on using GarageBand you can get rid of this as well. But there's even more because outside of Application Support in Audio you usually find Apple Loops and Apple Loops Index. Apple Loops are bits of sound that are used in GarageBand and Logic. You can get rid of those two folders as well to save space. Now if you want you could go back to the Storage Manager, like before, and then you can select Music Creation. You could see there is a button here Remove GarageBand Sound Library. This will get rid of some but perhaps not all of those files. So you may want to start with this and then go and check those four locations. 
Now another app that may take up a lot of space on your drive beside the App itself is Xcode. Xcode is Apple's developer tool and if you've ever just downloaded it to play around with it, maybe to learn some new skills, but you're not using it day-to-day as a developer you may want to get rid of Xcode and all of it's supporting files to save some space. So when trying to get rid of some of the files from Xcode where you want to look first is in the Storage Manager. Look under Developer. Then you're going to see all these different things. If you're not using Xcode changes are you don't need any of these. But even if you are you may want to get rid of some of the older iOS versions if you're not testing on those. Same thing for Watch or sometimes TV OS versions will be here as well. Then you could look for Xcode Caches, Project Archives, and Project to build data and indexes. You can delete any of these. You can also Shift Click to select multiple ones and Delete. Even if you're done with those go into your User Folder, into Library, using the Option Go Menu there. Then go to Developer and then Xcode. Then look for User Data here and IBSupport. Then you'll see simulator devices here. If those haven't been cleared out already you can clear some of those out as well. Then back at the Xcode level look for Drive Data and you can get rid of stuff left over from some of your projects there if it's not needed. These will be regenerated if you work with those projects again. 
At the top level in the Library folder there, so not in your User Folder but the main Library Folder, look under Developer and then you're going to see Course Simulator. You'll see some profiles, runtimes, and things under that. If you see anything there you may want to get rid of it if it wasn't already gotten rid of. This is iOS 13 runtime. I don't need that so I can get rid of that. You find those in Xcode Preferences and then Components and then you can see it right here. You just can't delete them from here but you can easily redownload them. 
Now another thing you may have on your drive are some old iPhone or iPad backups. You're probably not using iCloud to backup those devices but maybe sometime in the past you backed them up to your Mac and those files are still lying around and they can be huge. Now the easiest way to find those is to go into the Storage Manager just as before because doing the Finder you'd have to connect each device and then go to Manage to backup those devices. But here you can actually look for iOS files here on the left. You can select those and you'll get a list of all your old backups. You can select and Delete them. There used to be time also where you would update our iPhones and iPads through out Macs or maybe you still do it that way. You've got those files lying around. If you go to the Library Folder there holding down the Option Key and then you look for iTunes here and in there you may see some of these old iOS updates. Of course you can delete those. Your iPhone and iPad are probably way past those updates and you could just update those devices directly now. You don't have to go through your Mac. 
Now in the Library Folder there's a folder called Application Support. If you go into that you get folders for different apps that want to store parts of the app itself, different libraries, in here. So let's go and sort these by size. Now the problem is folders sizes aren't shown. To show folder sizes you want to go to View, Show View Options, and turn on Calculate All Sizes. We're going to use that technique a lot. Then wait for it to calculate everything. Then you could see which apps may be taking up a lot of space. What you want to look for here are not apps that you are currently using. You don't want to disable those by removing their things here. But maybe an app that you're no longer using. Maybe one you stopped using awhile ago or an old version of an app that you're no longer using. Then you can get rid of those. You also want to go to the computer level and then into Library here and do the same thing under Application Support. Sort by Size, Show View Options, Calculate All Sizes, and see what's taking up a lot of space. So Adobe has got quite a bit of stuff as well. Then most of the rest of the stuff down here is too small to worry about. 
Now once you go back to the top level and look in System. Now System is protected. You can't change what's in there. But I want you to take a look and see how much space your voices are taking up. These are the voices used for text to speech or for Siri. So you go into System and then into Library and then you're going to look in two places. One is Speech. Get information on Speech to see how big it is. That's 1G. Also go to the top and you'll see Assets V2. Go in there and then turn on Calculate All Sizes.  Sort By Size and see what seems to be Speech. You could see here Voice Services. So that's a voice as well. Mac Can Talk voice assets. That's something as well. So you can see about 3G there. So 4G total. So you may want to deal with this by getting rid of some of the voices. The way to do that is to go into System Preferences and then to Accessibility and then to Spoken Content. You're going to see System Voice here. Now select that and go to Customize. Then you'll see checks next to all the voices that you currently have loaded. Maybe at some point you went through and checked a whole bunch of these thinking it would be fun to play around with some of the voices. But now you want that space back. So what you want to do is uncheck any you don't think you'll need. The Siri voices are the largest ones. So you want to kind of figure out which of the four Siri voices that you want. Save that one and get rid of the other three. I would keep around a few like Samantha and probably Alex. They are some default ones. They are really small anyway. Those older voices. Then you could click OK and it will get rid of those voices. Again you can't change the System folder here. So the only way to do it is using System Preferences and customizing the voices. 
Now usually when people talk about clearing out space on a drive they talk about caches. Getting rid of the caches. Clearing out the caches. But most of the time you don't want to do that. The whole point of a cache is to speed things up for you. It's to take files that you're going to need all the time, either stuff that's from online or stuff generated by apps, and have them there ready to go. Clearing out the cache; all that's going to do is slow you down the next time you use that app. It's going to regenerate them anyway. So it won't save you space. It will just make things slower and it could eat up your bandwidth if it has to redownload those. But, they still are worth checking out. Go to your Library folder here and then look for Caches. Go into there. Do a sort by size and just like before Calculate all Sizes so you can see the folders mixed in there. See what you've got. For instance, here's a perfect example. I'm now using Screenflow 10. Screenflow 9 has a cache in here. I'm no longer using it. I'm never going to run it again and it left behind this cache. So I can delete this cache and get rid of that. So willy-nilly go through this. Just look at the largest things. Think about if you really need those or not and delete them if you don't think you'll need them again or anytime soon. 
Now if you've gotten some images with attachments in Messages, and who hasn't, they can take up a lot of space. So you can go into Messages and if you see one you can Control Click on it and you can Delete it. But you're not going to scroll back through all your conversations to find the largest ones and delete them. Instead go into the Storage Manager, just like before, and if you have more than just a few images and other attachments you should see Messages appear here on the left, and you could select it and then sort through it just like you could the podcasts and books and TV shows. 
Now how about your photos? They take up a lot of space, right. Well, go to Photos, Preferences and then look under General. Then you'll see Library Location. So you want to pay attention to that. That's where all your stuff is stored. You can actually click on it to jump to it and here you can see it's in my Home folder under Pictures. That's usually where you'll find it and this is usually what it will be named. I can select that do Command i and it will show me the size of it. So you can determine whether or not this is something you need to worry about. Now if it is pretty big there are a few things you can do. One is that you can go in Photos, Preferences, again, to iCloud and turn on iCloud Photos. Now yes this means it will upload all your photos to iCloud, and Yes you'll probably have to pay for storage. $3 a month or something like that. But what will happen is it will off-load the photos that are the oldest, the ones that you haven't viewed very often, and put those in iCloud and it won't take up space on your Mac. You have to Optimize Mac Storage turned On for that space saving to happen. In addition to that you get to have all your photos available on your iPhone, your iPad, maybe your other Mac as well. It's kind of a nice feeling that your photos aren't just on your Mac and maybe your backup drive that's sitting next to it. That they are somewhere else in case there's a disaster that takes out those two things. But do note you don't see the savings right away. It will take time for everything to upload and for some of the older, less viewed photos to be off-loaded. So they are only here on demand not stored on the drive. 
Now another thing you can do is you can get rid of videos from this. So, I don't like to store my videos inside my Photos App. I like to put them elsewhere. So if you have some videos in there it's just a matter of selecting them and then you can do File, Export, Export Unmodified Original For this many videos. Then you can Save those out. Then name them something nice. Put them in a nice folder organization somewhere, maybe on an external drive even. Now the main thing you can do with your iPhone's camera is take short videos. You probably don't want to do this. You want to have your videos there for you to see in your Photos Library. But if you're like me and mostly take photos and only occasionally do videos then this might be a good option and a great way to save space because videos take up a lot more space than photos do.
Now another you may want to do is look for old photos libraries. Maybe you duplicated your Photos Library at one point as a backup or maybe you created a separate one for something special at some point. In the Finder do a Search and search for .photoslibrary. Then use Name Contains That. Then have it search This Mac. It will come up with any old photos libraries that maybe you can get rid of. You can select it and hopefully you remember why it's there and what's in it based on its location. Also search for .iphoto. It will find any old iPhoto Libraries from before the transition from iPhoto to Photos. As a matter of fact a lot of people when they transitioned they left their old iPhoto Library around for awhile just to make sure everything was okay. Maybe you forgot about it and now that you know everything is fine you can get rid of that old library that's way out of date. 
Another place you may want to look is your Downloads folder. You can find that by going to Go, and then Downloads and this is, of course, where you downloaded things either in Safari, another browser, maybe Mail. A lot of times people forget they put things here and this could really add up. The best practice is to, of course, download something to your Downloads folder and either use it right away, like it's an installer, or put it in its proper place in your Documents folder or wherever, so nothing accumulates. But if you've let things accumulate maybe deal with each one of those items now and clear out your Downloads folder. 
Of course another place to look is the Trash. You can get to it in the Dock by just clicking on it and it takes you to the Trash Folder. Now the Trash Folder is just a safety net. It's meant to be a temporary storage place and then you could Delete the files in it later on. You should never put anything in the Trash that you're not willing to have deleted immediately. So if you practice that and now you notice your Trash is pretty full because you haven't emptied it for awhile, empty your Trash. Go to Finder, Empty Trash, and get rid of everything. If this is becoming a problem for you, having your Trash full of files for you to empty them, you can go into the Storage Manager. If you look under Recommendations you'll see Empty Trash Automatically. You can turn that On with a button here and any file that's older than 30 days will be deleted. 
Now, of course, some of the biggest files on your drive are probably in your Applications folder. You go to the Applications Folder, go into List View and then Sort By Size. You do want to turn on Calculate All Sizes because sometimes applications are stored in little folders. Now you could see which applications take up the most space. Sometimes they are things you don't need anymore. Like maybe a game that you've finished. Now you can get rid of. To delete an app the best way to do it is to go into Launchpad. Click and hold any icon and then click the X to delete the app. This is the cleanest way to do it. Some apps you won't see that because they are System apps. You can't delete those and other apps you won't see them because they weren't installed by the Mac App Store. In that case you should find out from the developer what the proper way to uninstall the app is. Usually it's something simple like dragging the application from the Application Folder to the Trash. But for some apps it's more complex like there's an Uninstaller App that they want you to run or process they want you to follow. It depends on the developer. 
Now if you want you can look for large email messages and delete those as well. So go to whatever folder holds all your email messages. It's usually for gmail or iCloud. It's like an Archive Folder. Or you may have arranged things in different folders. Usually it's something like Archive. But you can also select multiple folders like that. It will show you the contents of all those folders. So now you've got a list of basically all of your old emails. Then go to View, Sort By Size, then you'll see the largest email message at the top. Maybe something that has a huge attachment. You can delete it and save a bunch of space. Although in most cases you're not going to find an email that's really worth your time deleting just that one message. 
So now we get to your files. After you've looked everywhere else it basically comes down to your files. Those can be stored in many different places. But one thing you may want to do before you start digging down is to see if there's any big file out there that you can get rid of. So go to a Finder Search, like this, and change Kind to File Size. You may actually have to look under Other to do a search for File Size and select it there. Then do File Size is greater than and something like 100 megs. Then change the search area from Documents, or wherever you started, into This Mac. It will find all of the biggest files that you've got on your drive. If there's something you don't need anymore you may want to get rid of it. You can actually throw something directly into the Trash from here by selecting it and then dragging it to the Trash or Command Delete and put it in the Trash. But a lot of times the big things aren't individual files. They may be a folder filled with files. So how do you figure out what's taking up a lot of space. Well, you need to go to one of two places to see all your documents. One is your User Folder and the other is iCloud Drive. You can Go and then Go To your User Folder called Home and that's where you'll see things. You may see your Documents and Desktop folders here as well depending upon your Settings. If not you'll still see things like Movies, Music, Pictures, and such. iCloud Drive will give you all your iCloud Drive folders including things like documents and such. Now you want to Sort By Size and you want to turn On, Calculate All Sizes. Then you'll see what's taking up space. 
So here it's obvious that the main thing is Documents. I can dig down by opening this up. Then I could dig down further and continue to look down and see what's taking up a lot of space. You're basically taking an inventory here. You're looking through everything and trying to figure out what's using up a lot of space. If my Documents folder was 50 GB in size, I'm going to want to quickly dig down and find out what's using the bulk of those 50 gigs. There's really no substitute for doing this. I know a lot of people are going to recommend cleaning apps and such but you want to go through and really understand what you've got here. Not only to find files you don't need anymore and get rid of them but perhaps to clean up your organization so in the future you don't end up with a full drive not knowing what's taking up space. 
So here's a bonus one called Time Machine Local Snapshots. You're not going to find that anywhere on your drive no matter where you look. What they are are Time Machine Backups saved to your local drive. Say you have a MacBook, you have a Time Machine Drive, and you're backing up to that Time Machine Drive. But then you disconnect the drive and now you're traveling with your MacBook. It's still going to make those backups and it's going to use empty space on your drive to do it. Then when you connect the Time Machine Drive the next time it's going to take all those backups and move them to the Drive. So you didn't miss a backup even though the Drive wasn't connected. However, if you haven't connected your Drive for a long time it could eat up a lot of space on the Drive so the available space is less. You can get rid of Local Snapshots one of two ways. One is simply connect the Time Machine Drive, maybe you just forgot to do it for awhile. Now once it's connected let it do its backup. Leave it alone for awhile. Perhaps overnight and it should have everything backed up and the Local Snapshots are gone and you have more available space. If for some reason you really can't do that and you need to clean up space you can go into System Preferences and then go to Time Machine and then see where it says Back Up Automatically. Turn that Off. If you turn that Off it's going to leave all the Local Snapshots but it's going to take a few minutes to do it. So give it a few minutes and then turn it back On. What I would do is come back maybe a hour later to turn it back On or turn it back On when you next connect your Time Machine Drive. That will clear out all the Local Snapshots after a few minutes and make more available space. As I said for most people it's not a problem especially if your Time Machine Drive is always connected.
So there you go. There are a ton of places to look for extra files and things that could be taking up space on your hard drive. Hope you found this useful. Thanks for watching.

Is your Mac’s hard drive full, or nearly so? The long-term solution is to remember to get a larger drive on your next Mac, as it looks like you underestimated how much storage you need. But in the meantime, here are some places you can look to free up space on your drive.

The TV App
The TV app is one of the many places where large files can easily accumulate. If you have purchased movies or TV shows from Apple, then you may have downloaded them here. They can take up several GB of space each. But purchased video can be easily re-downloaded, so there is no need to store them here when you are in need of more space.
Launch the TV app and look in the left sidebar for “Downloaded.” If you see it there, you have some downloaded content. Click on that and see what you have.
You can click on the three-dots button on each item or Control+click and then select Remove Download to delete them.
But another place you can see these, along with sizes, is in the Storage Manager. Go to the Apple Menu and choose About This Mac. Then click System Information. Then click Storage at the top. Now you are looking at the Storage Manager. We’ll be using this utility often here. Click on TV in the sidebar. Now you can see all of the video content in a list. You can click on Size at the top to sort by size if you like. Select any item and you can click Delete at the bottom to remove it. You can even Shift+click to select a range of videos, or Command+A to select all, and then Delete.

The Podcasts App
You can do the same with the Podcasts app. Podcasts can be tricky because it is easy to subscribe to a daily podcast, forget about it, and find out you have months of large daily downloads stored on your drive, waiting for you to listen.
In the Podcasts app, look for Downloads in the left sidebar, then Control+click on any item and Remove Downloads. You can also see and sort a list in the Storage Manager, under Podcasts.

The Books App
In the Books app sidebar, look for All under Library. Any book you see with a little cloud icon is not currently taking up space. Everything else is local. You can just go through them and click on the three-dots button and select Remove.
But it is probably better to go to the Storage Manager and remove them from there. It is easier to see what you have and what is really taking up space, and what is not. Some books are just a few MB in size and not worth worrying about, while others can be 100s of MB or more.

GarageBand and Apple Loops
Ever use GarageBand? If you do, then you probably don’t want to delete it or any of the files it needs. But if you don’t use it, or having space is just more important right now, then look in these folders:
/Library/Application Support/GarageBand
/Library/Application Support/Logic
/Library/Audio/Apple Loops
/Library/Audio/Apple Loops Index

Note that these are all at the top level of your drive, not in your user folder. So open a new Finder window, choose Go, Computer. Then dig down into your internal drive (usually Macintosh HD) and then into Library. Then look at each of these four folders. If they aren’t there, that’s fine. Otherwise, select the folder and use Command+i to get the size of the folder contents.
That’s how much space you’ll save deleting these folders. You can do that one of two ways. One is to delete these folders. The other is to use the Storage Manager, select Music Creation on the left, and then press the big “Remove GarageBand Sound Library” button. But even then, you may want to go back and check these folders again as some of the items may be left behind because technically other apps, like Logic, can use them.

Xcode Files
Maybe you aren’t a developer, but one day you decided to download Xcode and play with it. Now you need some space and are willing to dump it.
In addition to the app, Xcode stores a lot of stuff in a lot of places. Here’s where to look. Note that anything starting with ~/ is in your Home folder Library folder. To get there, hold the Option key down and choose Go, Library. You won’t see Library in the Go menu until you hold Option.
~/Library/Developer/CoreSimulator/Caches
Note: Caches will just be rebuilt when you use Xcode. But if you aren’t using it right now, you can delete these to get some space back temporarily. Plus, if some of the cache is for old projects that you’ll never work with again, then it could be worth it. The best place to delete this is in the Storage Manager, in the Developer section.
/Library/Developer/CoreSimulator/Profiles/Runtimes
This is one place old versions of iOS are stored for use in simulators. There’s a good chance you don’t need them anymore. And if you do, you can always re-download them inside of Xcode.
~/Library/Developer/Xcode/Archives
When you build a project and send it into the App Store, the archive is saved here. But it doesn’t get deleted later when you have a new build. The best place to handle there is in Xcode, Window, Organizer. And keep in mind there are valid reasons to keep old archives around, such as using them to figure out debug messages sent in by user crashes. You can also delete these in Storage Manager, Developer. Look for Project Archives and Project Build Data.
~/Library/Developer/Xcode/iOS DeviceSupport
~/Library/Developer/Xcode/watchOS DeviceSupport
~/Library/Developer/Xcode/tvOS DeviceSupport
You can check to see if you have any simulators here you don’t need. Maybe you just want to test on the current version of iOS, or at least the latest version of each major release. The best place to delete these is in the Storage Manager, in the Developer section.

~/Library/Developer/Xcode/UserData/IB Support/Simulator Devices
Here’s another place you can clear out some things. Anything you need here would be regenerated when you needed them while using Xcode.

~/Library/Developer/Xcode/DerivedData
You can clean out old build data by opening a project in Xcode and then choosing Product, Clean Build Folder. But you’d need to open every project you have ever worked on to do it all. Instead, you can just delete the contents of this folder.

iOS Backups
If you still back up your iPhone or iPad to your Mac, you’ll have some large files containing these backups. Even if you have switched to using iCloud, you may have some old orphaned backups you can delete.
Go to the Storage Manager and select iOS Files. This is the easy way to see and delete them.

Old iOS Software Updates
Remember when we used to have to update our iPhones through our Macs? You can still do that, or maybe you just have some old updates left behind.
Check out ~/Library/iTunes/ and see what is in there. If you see a folder with updates you can delete it.

Old Application Libraries
Today Applications aren’t supposed to store much outside of the application itself. But some still put things in the Library folder. Worse, some apps you may have last used years ago may have left some things behind.
Go to ~/Library/Application Support in List View. Sort by size. Turn on Calculate All Sizes by going to View, Show View Options.
Now see what is taking up space. Notice some old app you don’t use anymore taking up a huge amount of space there? Delete it.
Also check in /Library/Application for more. These would be at the system level, not just for that one user.

Speech Voices
You can make your Mac read text to you, use Siri, and a variety of Accessibility functions that use speech. Maybe at one point you thought it would be fun to download a bunch of extra voices to hear what they sound like.
Go to these two locations to find voice:
/System/Library/Speech/Voices
/System/Library/AssetsV2/
Note the second location is not just for voices, but you can usually see which ones are voices by looking at the names. You can’t do anything to these files here and you shouldn’t try. This is part of the system and is protected.
So how to get rid of them? Go to System Preferences, Accessibility, Spoken Content. Where it shows System Voice, select that and go to the bottom of the list to choose Customize. Now you can uncheck any voice you want to remove. Some of these will barely save anything. Others, like the Siri voices, will save half a GB. Leave at least one Siri voice, and maybe Samantha and Alex there. The rest are up to your personal preferences.

Caches
So here is where a lot of advice goes wrong. You’ll hear people telling you to remove your cache files to speed up your Mac. Actually, the whole point of cache files is to speed things up. Deleting them will slow you down, at least while the caches are built up again.
Caches represent either downloaded data or data that needs to be generated for an app to work efficiently. Deleting it won’t hurt too much, but it will just regenerate anyway. However, sometimes there are cache files that were put there by apps you no longer use. You might as well get rid of those.
Go to these two locations, use List View, sort by size. Turn on Calculate All Sizes again. See what is large and what is labeled as coming from an app you no longer use, or maybe don’t plan on using again for a while. Delete those. Don’t obsess over the smaller folders. They aren’t worth your time.
/Library/Caches
~/Library/Caches

Messages
If you get a lot of messages in the Messages app, it could be worth checking out the largest attachments you have and deleting them if you don’t care about them anymore. No use keeping that meme GIF that someone from work sent you 6 months ago, right?
Go to the Storage Manager and choose Messages. Sort by Size. See if the largest ones are taking up too much space. Select and delete. Shift+select and Command+A works here too.

Photos and iCloud Photos
Launch Photos, then choose Photos, Preferences, and then General. See the Library Location? Go there. You can actually click it right there and it will open in the Finder. Now Command+i to see how big it is so you know what you are dealing with.
If you want to shrink it, one way is to use iCloud Photos. Yes, this will take up space in iCloud. Yes, you will probably need to choose a paid subscription plan. But for that you not only free up some space on your drive, you also will have your precious photos stored somewhere other than your house where a single disaster could make them vanish them forever. And you get to access all of your photos on your iPhone and iPad too. Not to mention the automatic syncing — never connect and sync your iPhone photos again!
Note that turning on iCloud Photos won’t make a difference right away. All of your photos will have to upload. Then over time some of the older, less viewed photos will be offloaded so they aren’t taking up space. You’ll need to make sure you choose “Optimize Mac Storage” in Photos, Preferences, iCloud to get the storage-saving benefits.

Videos
If your Photos library is big, one reason could be the videos. You can have a ton of photos in your library, but only a handful of videos could weigh more than those easily. One way I deal with that is to simply not store videos in my Photos library.
Instead, I put them in a separate folder in a separate location, often on an external drive. To export them from your library, select the video and choose File, Export Unmodified Original. Then delete the library copy as soon as you confirm you have the video as an independent file now. Then store them as you like. Good file names help here too so you can find them later.
This idea isn’t for everyone. If your main use of your iPhone’s camera is to take short videos, not photos, then you probably want those all in your library.

Old Photo Libraries
It is so easy to have old Photos libraries left lying around. Maybe you duplicated your library at one point as a backup. Maybe you create a new library for a special project and forgot about it. Maybe you upgraded from iPhoto to Photos back in 2013 and kept the old iPhoto library around just in case.
Do a Finder search for “.photoslibrary” to see what you can find. Then do one for “.iPhoto” for those old iPhoto libraries. Then access what they are and whether you need them anymore. Maybe archive them to an external drive if you want to keep them, but want to save space on your internal drive right now.

Downloads Folder
When you download something from your web browser or even an app like Mail, the default location is the Downloads folder. Perhaps your Downloads folder has accumulated a lot of junk you don’t really need?
It is best practice to download something and then immediately move it to a better location, or use it right there if it is an installer of some kind. Then delete it. But if you haven’t done that, it may be time to look through this folder and get rid of everything you don’t need anymore, and more things you do want to the Documents folder or elsewhere.

Trash
The Trash (Bin) folder is another place things accumulate. You should never put anything in the Trash unless you are fine with it disappearing forever immediately. It is a safety net, not a part of any workflow.
So if your Trash has some things in it, it is a good idea to empty it often. Look inside now and sort by size to see if you can expect any relief from this if you want. But empty either way.
If you find that your Trash often gets pretty large, then go to the the Storage Manager and click Recommendations at the top. Then look for Empty Trash Automatically. Click Turn On. Now items that have been in the Trash for more than 30 days will delete themselves.

Applications
I previously mentioned files used by GarageBand and Xcode. If you want you can delete both of those apps in addition to their Library files.
Use LaunchPad to do this. In LaunchPad, click and hold any icon. Then click the X above any apps you wish to delete.
If you want to see what other apps are taking up space, go to the /Applications folder. Sort by size. Turn on Calculate All Sizes too, as some apps may be storing themselves inside of folders.
Now you’ve got to make judgment calls. If an app takes up a lot of space and you don’t really need it, consider deleting it. To delete an app, use LaunchPad. If the X doesn’t appear for that app, that means it could be a system app that can’t be deleted. Don’t worry about those.
Other apps that LaunchPad can’t delete are third-party apps you may have downloaded. These require that the developer provide some sort of official uninstall method. So go to the developer documentation or website and look for that. Often it is as simple as just moving the app from the Applications folder to the Trash and emptying the Trash.

Large Mail Messages
Normally a single email message isn’t going to use much space. But maybe someone emailed you a huge file at some point and that one message can be deleted so you can recover some space.
In the Mail app, go to each email account in the left sidebar. Choose the mailbox/folder that represents where you store most of your saved messages. For iCloud and Gmail, it is usually “Archive.” Then go to View, Sort By, Size. Now you can see if there is a message large enough to deserve your attention. Remember to set the sort back to date afterwards.

Find Large Files
After you have done everything above, you only have your own documents to worry about. The easy thing to do now is to search for unusually large files.
In the Finder, start a search. You can restrict your search to just your Home folder or just iCloud Drive if you like by starting there. Or, choose “On My Mac” at the top of the search window to look everywhere.
Then set up the search for “File Size” is greater than 100 MB. You’ll probably have to choose “Other” as the search criteria and then look for “File Size” in the list.
See if this reveals a few huge files that you maybe forgot about and don’t need anymore. You can select them and Command+Delete to move them to the Trash right here from the search results.

Examine Your Documents
So this leaves one more thing, your own document files. They are probably in only one of two places: your Home folder and your iCloud Drive folder.
Go to each one, use List View, and turn on Calculate All Sizes. Then click on the little triangles to the left of any folders to peak inside and dig down. Use this to figure out which folders are taking up the most space and see what you have inside them.
If you see something you don’t need, delete it. If you see something you don’t need but want to keep around, move it to an external drive to archive it.

Bonus: Time Machine Local Snapshots
One more thing that could be using space is Time Machine Local Snapshots. Say you have a MacBook and have set it up with Time Machine. But you haven’t connected to the Time Machine drive in a while. Your Mac will still back up data, but it can’t put it on that Time Machine drive. So it stores it in unused space on your drive until it can.
Now this should only use unused space. But your Mac can’t read your mind and know you need to 30 GB to download some video file, so it won’t know how much space to leave free.
To clear out local snapshots, simply connect your Time Machine drive and allow it to continue its regular backups.
Or, if you simply can’t do that and don’t mind maybe losing some backup data since the last time you connected that drive, you can clear out Local Snapshots another way. Just go to System Preferences, Time Machine. Turn off Back Up Automatically. Then wait. Give your Mac some minutes to delete the Local Snapshots. Then turn it back on again.

Gary: is the only way to get the advanced search window by pressing Ctrl F" ? I thought there was an icon or menu option for this. thx

sorry..meant CMD F, btw couldn't see in your video how you start a new advanced search in a new tab. thx again

Gary Rosenzweig

nick: If you just start typing in the search field, you can then click the + button and add the size criteria. But it makes more sense to use Command+F to get there.

Great advice... my Outlook Message Sources file under users etc is 199GB. Can I delete it? And, what is it? I use outlook for all my email...I do not use the mail app. Thank you!

Paul: I don't use Outlook so I can't say for sure. But it would make sense that it is your Outlook email messages and that deleting it may delete your Outlook email. It probably depends on your settings. I can't help much since I don't use Outlook so I can't investigate. I'd ask in a forum for Outlook users how you can reduce that.
