Just a quick look at Dark Mode. Is this a feature you are looking forward to?

If you have a large Numbers table and regularly search and filter it, you may want to use a formula and a filter to enable quick and easy searches instead. The technique involves creating a hidden column that will use a single-cell second table to search, and then a filter based on the results in that column.

Computers come with one of two types of internal storage, either a Hard Disk Drive or a Solid-State Drive, also called an SSD. Hard Drives are older and cheaper technology, but also slower. SSDs are newer, smaller, faster, but more expensive. You can also get Macs with a Fusion Drive, that is a hybrid of the two.

You can easily save a portion of a webpage or document as a streamlined PDF or Image file. However, many people take screenshots instead, which are poor resolution. Using the Open In Preview function in the Print Dialog, you can quickly and easily convert portions of webpages or documents to smooth and scalable PDFs or even higher resolution images.

Instead of dragging and dropping files to move them in the Finder, you can simply use Copy and Paste. This will create a copy of the file in the new location. But if you hold down the option key, this moves the file instead. This is similar to cutting and pasting files in other operating systems. You can copy and paste multiple files.

You can set your Safari home page to any page on any site. However, this won't actually affect much unless you also set other options in your Safari Preferences. Even then, when you quit Safari and relaunch it, you'll probably just see the same pages you had open previously, unless you close all of Safari's windows before quitting.

So I like those notifications that appear at the top right corner of your Mac's screen. I sometimes create "right now" reminders so that I get one of those and it bugs me until I do the task.Instead of adding to my Reminders list with these, and seeing them on my other devices, I've come up with a JXA script that I can easily trigger that will put one of these notifications on the screen. Here is the script I am using: <blockquote>app = Application.currentApplication(); app.includeStandardAdditions = true; var message = app.displayDialog('What?', { defaultAnswer: "" }).textReturned; app.displayNotification(message,{withTitle: 'Reminder'})</blockquote>

People sometimes use the terms Internet and Web interchangeably. But the Web is just one of the many ways you can use the Internet. The Internet is the global network of computers, whereas the Web is just the part of the Internet we use when we browse web pages using a browser such as Safari. The history of the Internet goes back further than you may think.

If you want to permanently delete files from your Mac and your Time Machine backups, you must use a special function in Time Machine to remove all of the versions of that file. After deleting the current file on your drive, you need to Enter Time Machine, look back to a time where that file existed, and then select the file to delete it from all backups.

A new feature in Numbers is the ability to round the corners in column and bar charts. You can use this to soften the corners or to completely round the ends of the bars. This also works in the latest versions of Pages and Keynote.

You can use the Pages Per Sheet setting in the Print dialog box of almost any app to combine 2, 4 or more pages to one sheet of paper. This makes the print smaller, but can be useful if you are trying to save paper or only print a backup copy of some information.

This simple app that will come as standard in iOS 12 will let you measure things in the real world using your iPhone's camera. In reality, though, the measurements aren't accurate enough for any real use, so I'm not sure about the purpose of the app other than to show off a bit of augmented reality.

Safari keeps a cache of files to speed up page loading and minimize bandwidth usage. For the most part it maintains itself. But if you need to clear the cache while publishing or developing a website, you can do so using one of several methods in Safari. You can clear all data from a specific site, enable the Develop menu to clear the cache with a keyboard shortcut, or manually delete the cache files in the Finder.

Wi-Fi is a made-up term that refers to the way we connect wirelessly to our networks and the Internet beyond. People use a variety of terms to describe Wi-Fi Base Stations, but each has a subtly different meaning.

Tags are useful for many things. One idea is to use them to flag files to gather them together for a single use without moving the files from the folders where they reside. For instance, you may want to gather together files to send to someone or save a copy to an archive.

Want to see all sorts of data about your mobile signal strength on your iPhone. If you dial a secret number you get into a special Field Test Mode with all sorts of menus. I'm not sure what a lot of this means, but I assume you can use this to see the signal strength of your current connection, and perhaps things about your SIM card and such.Guaranteed to break the ice at parties!
