Question: Unlock with Apple Watch Not Working
I am running a mid-2013 MacBook Air with macOS Sierra, with a 2nd Gen Apple Watch running watchOS3. I am on the same Apple ID for my Air, Watch, and iPhone (6S).
But, unlock with Apple Watch is not working on my Air. I have enabled 2 Factor Authentication. I have checked the box that enables unlock with Apple Watch. Everything seems to be kosher.
When I close and reopen my Air, "Unlocking with Apple Watch" appears for about 10 seconds, then I have to enter my password.
MacBook Air, macOS Sierra (10.12), null
