Unlocking Macbook with Apple Watch

Hello


I have been able to use my Apple Watch (SE) to unlock my MacBook Pro (M1) in the past. Yesterday, I added another user to the Mac (signed in with a different Apple ID). The user switching is quick and effortless and everything else seems to be working as usual.


Although, now I can no longer unlock even my original user account with the same Apple ID as used on the watch. the dialog box says that the Mac is unable to communicate with the watch, even though both are unlocked and even the iPhone is unlocked as it says. I understand that my watch can not unlock the Mac for the other user with a different Apple ID, but why is not working with the original account as well?


Please let me know if you need more details. Looking forward to a solution soon, and MERRY CHRISTMAS! 🎄

MacBook Pro 13″, macOS 11.1

Update to watchOS 7.2



If that does not work, it should, but if it does not work, then read the following threads

And


I also found that it took awhile for the iCloud Keychain records to propagate and merge on all the systems. More so when you have multiple devices sharing the keychain (I have 4 Macs, the iPhone, and the Apple Watch). I followed both of the above threads, but it was not reliably working until the next day, when I tried again. And I did have to click the enable check box twice the next day, but then it stuck.


And this thread says they also had to toggle the Apple Watch -> Settings -> Siri -> Listen for "Hey Siri" option off then on

Hints (you will understand when you read the first and second threads):

Applications -> Utilities -> Keychain Access


Finder -> Go menu -> ~/Library/Sharing/AutoUnlock


System Preferences -> iCloud -> Keychain

Hey viral5,


It sounds like you're having some issues with Auto Unlock for your Mac and Apple Watch. We can understand wanting to get that resolved. We want to help.


First, we'd recommend checking for and installing any updates that may be available for your Mac and Apple Watch:


How to update the software on your Mac


Update your Apple Watch


We'd then recommend restarting all of your devices, including the iPhone that's paired with your Apple Watch to see if that helps.


W'ed also suggest ensuring your password meets the requirements for Auto Unlock.


 Auto Unlock supports the use of the following characters in the your user password:

  • Uppercase or lowercase letters A to Z
  • Numbers 0 to 9
  • Underscores
  • Hyphens
  • Periods


If any characters other than these are used in the password, change your password in System Preferences > Users & Groups to a password that only contains these supported characters, restart, and test.


Thanks!
