Your Mac was unable to communicate with your Apple Watch WatchOS 7

No matter what I do, I keep getting this error. It was working before WatchOS 7. Now its not working at all.

Restarted all devices (iPhone, watch, iMac 2015 and iMac 2020)

Restarted internet

restarted bluetooth and WiFi on all devices

Re-paired watch to iPhone

Erased and paired watch to iPhone

Signed out and back in to iCloud

Deleted bluetooth plist

Literally everything I found online has not worked.

Macbook is unable to communicate with Apple Watch I have a Macbook Pro (2015) and an Apple Watch Series 4. Until yesterday, the 'unlock the Mac with the watch' feature worked seamlessly. Yesterday, I upgraded to an iPhone 12. It paired with the watch with no difficulty, but now I can't re-enable the 'unlock the Mac' feature. I get the error message that the Mac can't communicate with the watch. I've tried unpairing and repairing, restarting all three devices, turning bluetooth and wifi on and off (all are on the same wifi network), but with no success. Same error message.

macOS Unlock with Apple Watch not working I recently found that unlocking my Mac with my Apple Watch was no longer working and when I tried to turn on the feature I would get an error. Here is the checkbox for the feature: And here is the error: "Your Mac was unable to communicate with your Apple Watch" I have tried to follow all of the steps outlined in many of the other similar questions. These include: Restarting all of the devices. Re-pairing the watch. Removing entries from the keychain. None of these fixed the problem. The problem started sometime in the last month. Previously I was able to unlock my Mac with my watch. My devices are as follows: MacBool Pro on macOS 12.6 Monterey, iPhone 14 Pro Max on iOS 16.0.2, Apple Watch series 6 on watchOS 9.0. Another possibly related bit of info is that when I ran Console.app and tried to turn on the unlock feature an error "Watch missing LTK for Mac" appeared in the log.
