After updating to 27.2, I can’t unlock my MacBook Pro with Apple Watch

After updating to 27.2, I can no longer unlock my MacBook Pro using my Apple Watch. Has anyone else seen this, or is there a fix?

This happens occasionally after a macOS update, though unlock with Apple Watch is working fine for me on 27.2. When it happens, you need to either toggle the setting off then back on with a restart in between, or sign out of then back into your Apple Account. Try those in order.


Toggle Setting

  • Open System Settings
  • Click on Touch ID & Password
  • Toggle the setting to unlock with your Apple Watch to OFF

  • Restart your Mac
  • Return to the settings pane and toggle it back ON (then enter your password when prompted)

Usually, the above is sufficient. If not, then sign out of your Apple Account then sign back in.

Thank you for the help. I tried the steps you suggested, and they worked. I can unlock my MacBook Pro with my Apple Watch again.

For me, my apple watch doesn't even show up under "Touch ID & Password" in System setting. Never had this before. Updated to MacOS 27.2 this morning and problem started immediately after.
