Long gone are the days when you needed to type a password to unlock a Mac. Alongside using Touch ID on compatible MacBook Pro models, customers using both an Apple Watch running watchOS 3 and a Mac purchased no later than 2013 running macOS Sierra can unlock their machine by wearing their Apple Watch.
Apple boasts that Auto Unlock allows users to log in before they even sit down, with the Apple Watch detecting when its in close proximity of the Mac, unlocking the machine without even needed to touch a single button or key. – Follow the steps before and discover how to enable Auto Unlock on your Mac and connected Apple Watch.
1) Open Settings on your Apple Watch, go to → Passcode → Turn On Passcode and enter a passcode.
2) Click on the Apple Icon () in the upper left corner of your screen and select System Preferences.
After completing the above steps, and when your Apple Watch is within a few feet, or about 1 meter, of your Mac, the Mac will automatically unlock. Unfortunately and to the disappointment of many, Apple doesn’t allow Auto Unlock on older Macintosh hardware.
It’s important to remember Auto Unlock won’t work after the Mac is shutdown or Restarted, similar to Touch ID on the iPhone and iPad.
