Your Mac was unable to communicate with your Apple Watch.
Recently bought an iPhone 8 Pro and Apple Watch Series 8 to compliment my M1 Macbook Pro. Try as I might, I am unable to select the checkbox under Security & Privacy labeled "Use your Apple Watch to unlock apps and your Mac". My iPhone is unlocked as is my iPhone. The error reads:
"Your Mac was unable to communicate with your Apple Watch."
This previously worked on the Apple Watch Series 6 with the same Macbook Pro. I have tried every troubleshooting step I can find (and there are many) including:
- Deleting "Auto Unlock" and "AutoUnlock" entries under Keychain Manager
- Resetting bluetooth/wifi on mac and iPhone
- Resetting Handoff
- Restoring AppleWatch from backup and new
- Resetting iCloud Password
- Signing in/out iCloud from Mac
At this point I am at a loss. During all this troubleshooting I somehow managed to get the checkbox to stick once although I haven't been able to do so since. Even then, the unlock feature didn't work -- it spun and eventually timed out which is the only reason I unselected it in the first place.
Is anyone else seeing this? I realize this feature hasn't exactly been rock solid from the start judging by the posts dating back years but the fact that I had it working once with my old watch tells me there is hope. I could only find one other "recent" post from this guy who reported the same error, "Watch missing LTK for Mac" with a Series 8:
Console logs read:
