macOS Sierra is finally out. Here is a guide on how to install Apple’s latest and greatest on your Mac.
The first step is to check compatibility. Only certain devices are eligible for the upgrade. All of them will are from 2010 or newer. However, while the older hardware will still install Sierra. it will most likely be missing some features and performance. Models after mid-2012 should have no issues after the upgrade.
Here is a list of the compatible hardware:
Mac Pro (mid-2010 or newer)
iMac (late 2009 or newer)
Mac mini (mid-2010 or newer)
MacBook Pro (mid-2010 or newer)
MacBook (late 2009 or newer)
MacBook Air (late 2010 or newer)
The next step is to take a backup. The best backup for Mac in terms of upgrading versions and reinstalling the Operating System is Time Machine. Make sure you have more than one backup and then you can start the upgrading process. This is to protect against any issues with the backup media.
In order to install Sierra, you will need to be on at least Lion (OS X 10.7.5), Mavericks, Yosemite, or El Capitan. Apple has made the installation process easy. On any of the above operating systems, go to the App Store, click on the Featured tab and macOS Sierra. From this point, the files will be downloaded and then installed. At least one restart will be required. On Macbooks, make sure to be on mains power.
