If you are using a third-party email address as your Apple ID, you may need to change it if you are losing that email address or plan to move on to another email service. Apple has a page that spells out the steps needed to change which email address is used as your Apple ID.

People often use the term Virus when what they really should be saying is Malware. A computer virus is a very dangerous type of malware that can spread from computer to computer on its own. Malware is a more general term that can be correctly used to describe viruses, trojan horses, adware, spyware and more. It is better to use the term Malware unless you know for a fact that the problem is a virus.

There are many settings on a Mac that determine how the Dock appears. You can change the size, hide it when not needed, and even move it to the left or right sides of the screen. You can change these settings in System Preferences, or by Control+clicking on the divider line in the Dock.

The iPhone and iPad have a built-in dictionary that doesn't appear as an individual app, but as a resource you can access Safari, text editing and other apps. You can look up any work you have selected. You can also look up words directly and quickly narrow search results to only show the definition. You can customize which dictionaries are used as well.

You can use Preview to combine more than one image into a single image. By using a trick to start a new document, and then resizing, copying and pasting other images into the new document, you can create a collage of images. Then you can export in the format of your choice to use in video projects, online posting, and so on.

You can use the wildcard characters question mark and asterisk in some Numbers functions to get more powerful results. In this example, we'll look at using a SUMIF function that sums rows that match only a portion of a string, rather than an exact match.

People often confuse storage and memory, but they are two different things in your computer and mobile devices. Memory is temporary and helps your device perform complex tasks. Storage is persistent and determines how much data you can keep on your device.

A fairly new feature in Pages, Numbers and Keynote for iOS is the ability to add Smart Annotations. You can draw using the Apple Pencil or your finger and mark up a document. You can delete and move the marks you make. You can also view these on the Mac when you use iCloud to share your documents between devices, but you cannot draw new Smart Annotations.

You can do more with dictation than just typing. You can also indicate when you want text to be bold, italics, or underlined. Some people have trouble because they try to include the command with the text they are typing, but it is important to wait between typing and issuing commands. In Pages you can even access everything in the Format sidebar using dictation commands.

Creating a custom Finder icon for a file or folder is as simple as copy and paste. However, a common problem people experience is when they try to copy and paste a whole file as the new icon and get a generic image icon instead of the picture. The trick is to copy the image inside the file, and not the file itself.

The Memories feature in the Photos app will alert you with new Memories albums from time to time. If you'd rather certain dates, people or locations not trigger memories in the future, you can indicate that. If you'd also like to disable the notifications for memories so you can just ignore them, you can do that as well on the iPhone, iPad and Mac.

While there is no pivot table function in Numbers, you can simulate the most common uses for pivot tables using formulas, filters and hiding columns. In this example we'll look at a table of sales numbers and see how you can sum the number of sales for each product listed. Initially you end up with the first row containing each product showing the total for every sale for that product. But you can filter the list to only show those rows. Then you can hide columns that present excess data to end up with similar results as you would with a pivot table.

Don't avoid using the iPhone's Do Not Disturb feature because you are worried you will miss an important call of message. You can set specific contacts to ring through the Do Not Disturb barrier by setting them up as a Favorite contact. You can also enable Emergency Bypass for individual contacts to bypass Do Not Disturb for calls and messages. You can also inform important people in your life that simply calling twice in three minutes will allow their call to get through in an emergency.

You can do more with Mac dictation than just typing text. You can use commands to control your Mac. You can select menu items, interface buttons and move between fields in the interface. In this example, I'll start, address, compose and send an email message without even touching the keyboard or mouse.

In addition to getting a sound and vibration when you get a notification, you can also choose to have your iPhone's light flash. You turn this on in the Accessibility settings. This can help anyone who may be in a situation where they can't hear or feel notifications, such as while listening to music or working in a situation where silence is needed.

You can quickly and easily create a website photo gallery using the Photos app on your Mac, iPhone or iPad. You can simply make it public and share the URL with your friends and family. Once the gallery is created, you can easily add more photos to it.

On the iPhone and iPad you can record video and at the same time take still photos. This can come in useful if you can't decide where to capture a scene in one of the other, or you want to record video of an event and also take high-resolution photos while recording.

On many recent MacBook models you will get an audible chime when you plug the machine into power. But if you have one of the models where this is not on by default, you can use a Terminal command to turn it on. If you'd rather not hear this sound when you plug in your MacBook, you can also disable it.

For each account you have set up in Mail Mail, you have the ability to set mailbox behaviors. These determine where messages are stored. You can set the destination for sent email, drafts, junk, deleted and archived messages. Your options will depend on your email service. When possible set these to use the cloud-based options so that the messages are seen across all of your devices.

In the Photos app you can hide photos both on the Mac and on iOS. Hidden photos will disappear from Photos view, albums and other views, but they will appear in a special Hidden album. This feature is not meant to be a secure way to protect photos, but just a tool to hide photos before deleting them or to take off photos out of normal viewing methods when they don't belong there.
