Apple has released the final version of macOS Siera a few days ago and users can download it from the Mac App Store. The new operating system for Macs introduced Siri – the popular digital assistant, Apple Pay, which is authorized using an iPhone, and other features such as Auto-Unlock (for Apple Watch owners) and Universal Clipboard.
Below, we’ll tell you how to you can get and install macOS Sierra on your Mac.
Before proceeding with the installation of macOS Sierra, it’s recommended to back up your Mac using Time Machine. So, in order to perform a full backup using Time Machine, follow these simple steps:
- Choose a new hard drive that will be erased, or connect your Mac to an external hard drive;
- When you will be asked if you want to use the drive to backup your Mac, click on “Use as Backup Disk”;
- If the message doesn’t appear, go to System Preferences > Time Machine, then click “Select Backup Disk” and choose the external drive;
- Turn on Time Machine.
In the system preference pane of the Time Machine will appear a progress bar and you will have to wait until the backup will complete. Then, you will continue with the installation of macOS Sierra. First, you will have to download the update from the App Store, and you will be required to fill out your Apple ID information. You will see the download progress in your Purchases tab and when it’s finished, the macOS Sierra installer launch will appear. You will see some on-screen instructions which you will follow correctly.
Depending on the specs of your Mac, the installation process could take up to half an hour.
If you want to install macOS Sierra on an external hard drive, choose a USB 3.0 drive if your device doesn’t support Thunderbolt drives. Now, after connecting the external hard drive to your Mac, launch Disk Utility (by heading to Go > Utilities), then in the sidebar you will select the drive and click Partition (Partition Layout must say 1 Partition) and give it a name.
Make sure that Guide Partition Table is selected in Options. Click OK, then Apply and Partition. Now, you will download the macOS Sierra installation from the Mac App Store and open it, click Continue, Agree and Agree, Show All Disks and highlight the external hard drive. Finally, click Install, type in your Admin password and that’s it.
Now, you will go to System Preferences > Startup Disk and choose the drive on which Sierra will run after restart.
