How to prepare your Mac for macOS Sierra

macOS Sierra's public beta is pretty easy to install. However, before you perform any big update to your Mac, you should complete a few tasks to ensure that your Mac is ready to go.

Back up your Mac before installing

Backup your Mac before installing OS X

No matter what, we recommend a full back up before you install macOS Sierra. Apple makes it easy to back up your Mac using Time Machine, so there is no excuse not to create a Time Machine backup before installing macOS Sierra.

Follow these steps to back up your Mac using Time Machine.

  1. Connect an external hard drive to your Mac. Choose a new hard drive, or one that you don't mind erasing.
  2. An alert may appear asking if you want to use the drive to backup your Mac. If so,  Use as Backup Disk.
  3. If not open System Preferences > Tim Machine and click Select Backup Disk. Choose the external drive.
  4. Switch Time Machine to On.
  5. A progress bar will appear in the Time Machine system preference pane. Wait for the Time Machine backp to complete before continuing with the macOS Sierra installation.

Follow these instructions to install the beta.

  • Once you've backed up your Mac, you can go to Apple's beta program site to enroll your Mac. (Here)
  • Click Redeem Code to launch the Mac App Store.
  • Click Redeem to begin the download. Download progress will appear in your Purchases tab.
  • Once the download has finished, you'll see an installer launch. Follow the instructions there to finish installing the beta.

Once downloaded and installed, you'll find that the Beta comes with a built-in Feedback Assistant app that appears in your Dock. You can report issues you find within the software to Apple using the application.
