Apple Watch will unlock one MacBook but not another
I have 2 MacBook Pros. A personal one and one from work. My watch was working fine to unlock my 13" 2018 MBP but not my 16" 2021 MBP. The most recent software update, my watch disappears from the 13". I was able to add it to the 16" but he 13" give an error now:
"Your Apple Watch must be signed in to iCloud to allow it to unlock your Mac" I've tried most things I can find online with keychain, etc and it's not working. Anyone encountered this?
