How to unlock your MacBook with your Apple Watch
With MacOS 10.12 (MacOS Sierra), Apple advertised that it will be possible to unlock your MacBook with your Apple Watch. You also need iOS 10 and WatchOS 3. I couldn’t wait to try it out, followed all the steps you could read in various articles online but I just didn’t get it to work. I managed to get to the lock screen and had this little animation spin looking to unlock the Mac with an Apple Watch but eventually, it didn’t unlock and I had to enter the password. As this process took me much longer than just immediately entering the password, I reversed the “unlock with Apple Watch” setting and contacted Apple Support on Twitter. They sent me the same instructions that I had already gone through (enable two-factor authentication, check “Allow your Apple Watch to unlock your Mac” in the Security & Privacy settings and then all the troubleshooting: un-pair and repair Apple Watch, sign out and into iCloud etc.). Nothing helped. They wanted me to open an official case with them but I was convinced it was a bug and they will fix it.
Today was the magic day! Not doing anything my boyfriend got a notification on his Mac that it will now be possible to unlock the Mac with the Apple Watch. He texted me and I thought, maybe Apple did something and now it works for me, too! And tadaa, it worked – on both my MacBooks, private and work! I’m a happy person!
