The term Bandwidth is used to describe data transferred over time. However, it is often misused to define a limit on total data transfer. Bandwidth is measured in bits per second, usually using kilo or mega-bits to make the numbers more reasonable. Marketing departments often distort bandwidth to only show maximum or one-sided numbers.

Did you know about the Grapher app that comes with your Mac? Well, even if you did, did you know it can animate graphs? And you can export them as videos?

The Open With command makes it possible to open a file with something other than the default app. But if you commonly need to do this with a specific app there are three ways to make it much easier to open the file with that app instead of the default. You could just drag it to the Dock icon for the app, add the app icon to the Finder toolbar, or create a keyboard shortcut.

Often people want to know how they can change the default font in Pages. But there is no default font. Instead, when you create a new document you are using a template, often the template named Blank. So if you'd rather start with a different font, then just create a new template that is a variation of the Blank one, and use that template instead.

With the new MacBook Air the MacBook line is stable for the next few months, making this a good time to buy a new MacBook. But which one is right for you? The MacBook is the lightest, the MacBook Air is the least expensive and good middle-ground, and the MacBook Pro is the most powerful with several major options.

If you have the Dock set to automatically hide, then you may not like the default amount of time it takes for the Dock to appear, and the speed of the animation. You can customize these by using the Terminal to change two hidden macOS preferences. You can delay the appearance of the Dock so that you can access other items at the bottom of your screen. You can also speed up or eliminate the animation if you find it is too slow for you.

Learn how to build a simple Siri Shortcut that will choose an item from a Reminders list and speak that item aloud. In this example, the Shortcut will get a random item from a list of chores.

Prior to High Sierra there was a Finder sidebar item called All My Files. This showed you a big list of all of your documents. This was replaced with the Recents list, which only shows documents you have opened and leaves out files you have created or downloaded, but haven't opened yet. You can easily re-create the All My Files list by making a Smart Folder and adding it to the Finder sidebar. You can customize this Smart Folder to better fit your needs.

If your Mac is too old to install macOS Mojave, you can still upgrade to the latest version of macOS that is compatible with it, even if you can't find those versions of macOS in the Mac App Store. Apple has pages for High Sierra, Sierra and El Capitan than include links directly to the hidden Mac App Store pages with those downloads.

A new feature of the Facebook app is the ability to take portrait mode photos from an iPhone X and post them as 3D photos. Right now to do this you need to have the latest Facebook app and enable this feature.

Multitasking on the iPad has been around for a while, but now you can actually view more than two apps on the screen at the same time. While two active apps can exist side-by-side, or one as a floating window, you can have two apps plus a floating window with iOS 12. Unfortunately, the floating window makes the two main apps view-only. You can even add a fourth window as a video picture-in-picture.
