How to Unlock Your Mac with Your Apple Watch

Now that macOS Sierra and watchOS 3.0 have been released, you can use your Apple Watch to unlock your Mac — retaining the security of your Mac, but having only to enter your password when you restart. This is one of the macOS Sierra/watchOS 3 features we have been most excited about at Big Man.

There are a couple prerequisites that must be met for the automatic Mac unlock to work. First, your Mac has to be from mid to late 2013 or newer. Here’s the list of compatible Macs. All Apple Watches are compatible. Another important prerequisite: You must have enabled two-factor authentication on your iCloud account. You can do that on your iOS device by going to Settings > iCloud > Tap your Apple ID (email address). Then tap Password & Security, then tap Turn on Two Factor Authentication. You also need to have a Passcode set on your Apple Watch.

Once you’ve met all the prerequisites, it’s as simple as opening System Preferences on your macOS Sierra Mac, going to Security & Privacy, and checking the box for the option “Allow your Apple Watch to unlock your Mac.” Once that is checked, enter your password, then everything should be all set up.
