Wireless connection is too weak to unlock with apple watch

I have a new(ish) MacBookPro 16in M1. I am getting "Wireless connection is too weak to unlock with apple watch" whenever waking it up. Usually it works if I click 'Cancel' and try again (as others have suggested) - but sometimes it needs several attempts. I don't think it's a watch issue as it unlocks my iMac (which is further away) reliably.


Is the connection via wireless LAN or bluetooth? No issues here with either otherwise.


Is this likely to be a hardware issue with the MBP or software?


OS 12.3.1; Apple Watch Series 4 OS8.5.1; iPhone !2 Pro OS 15.4.1

Apple Watch, watchOS 4

Thank you @WinsC1


  • I had already done everything you suggested (and the watch was unlocking my iMac fine so had to be a issue with my MBP.) The final suggestion in the Unlock your Mac with your Apple Watch article - "In Security & Privacy preferences, deselect ”Use your Apple Watch to unlock apps and your Mac,” then restart your Mac and turn this setting back on" does seem to have worked. Perhaps advice to restart after selecting that option in Preferences would help others.

I just got a MBP 2021 Apple M1 Pro and have an old Series 2 Apple Watch.


Solid failure on unlock. Never works. Messed around on checking/unchecking option on Mac. Restarted watch several times.


I have an old MBP 2014 and rock Solid acceptance on unlock with watch (and an older Mac mini too). Could my Watch be too old to support this on new MBP? Did somebody drop some function on option on new MBP and old watches ?


Hate to upgrade watch just for this?
