Is your Apple Watch strapped to your wrist? Is it unlocked? If not, do both before you attempt to re-activate Auto Unlock. Also, it’s a good idea to unlock your iPhone.

2. Disable and Enable WiFi and Bluetooth

Random connectivity issues with Wi-Fi and Bluetooth can stop your Mac from communicating with your Apple Watch. The quickest way to fix that is to reboot the Wi-Fi and Bluetooth modules on both devices.

Disable and Enable Bluetooth and WiFi on Mac

1. Select the Control Center icon on your Mac’s menu bar.
2. Expand the Bluetooth and Wi-Fi categories.

4. Restart Your Mac and Apple Watch

Restarting your Mac and Apple Watch is a quick way to resolve persistent software glitches stopping you from turning on Auto Unlock.

Restart Your Mac

1. Open the Apple menu and select Restart.
2. Clear the box next to Reopen windows when logging back in.
3. Select Restart again to confirm.

2. Select Software Update.
3. Select Update Now.

Update Your Apple Watch

1. Open the Launchpad and select Other > Keychain Access.

1. Select View > Show Invisible Items on the menu bar.

1. Type Auto Unlock into the search box at the top right of the Keychain Access window.

3. Open Finder and select Go > Go to Folder on the menu bar.

1. Visit the following directory:

~/Library/Sharing/AutoUnlock

1. Delete all files inside the AutoUnlock directory.

1. Restart your Mac.

8. Sign Out and Back Into iCloud on Your Mac

2. Tap All Watches.
3. Tap the Info icon next to your Apple Watch.
4. Tap Unpair Apple Watch.
5. Tap Unpair [Your Name] Apple Watch again to confirm.

After the reset procedure, set up your Apple Watch from scratch and choose to Restore from Backup after pairing it with your iPhone.

10. Check For Apple ID Mismatches

This isn’t a problem for most people, but if you use multiple Apple IDs, your Mac will not communicate with an Apple Watch you’ve signed into with a different account. Here’s what you must do to check the Apple ID on both devices.

Check Apple ID on Mac

1. Open the System Preferences app.
2. Select Apple ID.
3. Check your Apple ID in the top left corner of the window.

1. Press the Digital Crown on your Apple Watch.

To fix an Apple ID mismatch on a Mac, you must sign out of iCloud and back in with the correct account credentials. On an Apple Watch, you must reset and pair it to an iPhone with the same Apple ID as your Mac.
