Apple has released its newest Mac operating system, MacOS Sierra today. The most prominent feature is the Siri integration, but it also features a universal clipboard, optimized iCloud storage, a picture-in-picture video play, Apple Watch unlock, and a Apple Pay, according to Recode.
MacOS is a free update within the Mac App Store.
In order to download the update, your Mac has to be compatible. According to Apple, "all Macs introduced in 2010 or later are compatible. MacBook and iMac computers introduced in late 2009 are also compatible."
If you aren't sure what year your Mac is, click on the Apple in the upper-lefthand corner and click "About This Mac." Under the OS listed on top, you will see the year next to your model name.
Thankfully, you won't have to free up too much space to make room for the update, as it is only 4.78GB in size. Of course, you should still do a few things before updating your computer. First, go through and make that room you need, and delete anything else that you don't really need or use.
Then, perform a system backup so that you don't lose any of the important documents like your photos, schoolwork, or music. An easy way to do that is to use Time Machine.
Finally, all you have to do is go to the Mac App Store and click on the updates tab. The update should be listed at the top.
