I think this happened after an automatic update to macOS and couple of weeks ago. I'm running macOS 10.13.4 on a 2017 15" MacBook Pro and my Apple Watch 3 is running watchOS 4.3 (15T212). Everything used to work perfectly but now the watch won't unlock the Mac.
If I go to System Preferences > Security & Privacy the "Allow your Apple Watch to unlock your Mac" option is not checked. If I check it, I get prompted to enter my account password (which I do). I then get the following message dialog:
When I go to the Apple Watch app on my iPhone and tap my watch's name I can see the "Find my Apple Watch" option which is working. Also if I log into iCloud in a browser I can find the watch so I know it's signed in.
I have tried unpairing the watch, restoring it from a backup and setting it up as a new watch but it stubbornly refuses to let me unlock my Mac. This is driving me nuts!
Does anyone have a solution?
Thanks
