If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos. On your Mac, press the specified keyboard shortcut (the default key combination is Option-Esc). If text is selected when you press the keyboard shortcut, the selected text is spoken. Otherwise, available text items in the current window are spoken; for example, if Mail is the current window, an email message is read.
Although Macs are reliable machines, they are not exempt from hiccups. All you need to do is carry around a single USB flash drive to be ready for situations the require you to diagnose, repair, or experiment with Mac OS X.
One of the maintenance tools every Mac user should have available in case of emergency is a bootable copy of Mac OS X on a removable device. A clean installation of the operating system can help pinpoint problems and will come to the rescue in a bind. And since most Mac owners use a MacBook of some kind nowadays, portability is a valuable thing. That means carrying around a bulky external hard drive with cables is not always ideal. It turns out a tiny USB flash drive serves as a great alternative.
Not sure when having OS X loaded on a flash drive would come in handy? Here are just a few examples:

Now that you’re convinced, let’s figure out how to do this. First you’ll need an Intel-based Mac from the past few years. Second, at least a 16GB USB flash drive, such as this SanDisk Cruzer Micro for about $30 at Amazon. Keep in mind 10.6 Snow Leopard was used to demonstrate this tutorial, so I’m not sure how much space 10.5, 10.4, and earlier require. While they should be fine, squeeze those versions of Mac OS X on a 16GB drive at your own risk. And the third thing you’ll need to get the job done is your OS X installation DVD.
All done! That wasn’t too painful, was it? Yes, booting to the flash drive will be a tad sluggish, but it’s not meant to be used on a regular basis. This is mainly for diagnosing issues and trying potentially risky things in a virtual sandbox that won’t ruin any of your data. While you’ll hopefully never need to use it, having a bootable copy of OS X on a USB flash drive is a cost-effective, portable emergency tool for your Mac.
