Since updating my Apple Watch series 2 to the latest firmware (5.1.2) it's stopped unlocking my Touch Bar MBP. I've checked security and privacy on my MBP and the 'allow your Apple Watch to unlock your Mac' is still checked. They are both signed into the same iCloud account and bluetooth is turned on.

Any ideas how to fix this?

This has not happened to me in awhile, but I seem to remember that rebooting phone, watch, MBP seemed to fix this. This is assuming that all other parameters are set correctly, such as BT.

have the same problem. Any soltuions? I tried everything.
On the Mac I went into preferences > security and unchecked unlock with Apple Watch. Restarted both watch and Mac and checked the unlock with Apple Watch again. Been working fine since :)

It's been broken/inconsistent with my Series 5 for awhile. It's not the Mac, since my 3 works fine. Today it said 'unlocking with Apple Watch' for a few seconds then said 'Touch ID or use Password'

Two weeks ago, it was broken completely, just went right to 'Touch ID or use Password' didn't even act like it was looking for the watch. Again, Series 5 problem, Series 3 unaffected.

Or not: had same issue with my 3 a few weeks back.

Unfortunately, can't recall if simple reboot, toggling of Bluetooth, or signing in/out of iCloud fixed the issue.

It comes and goes for me. Reboot never fixed mine being inconsistent. I'm blaming my Series 5. The darned thing has been half baked since I bought it. Should have stuck with the series 3. Might go back to it. I've been quite unhappy with the 5.

I have found that using a USB-A (USB3) port on my Mac mini interferes with the Bluetooth connection between the Watch and the Mac. Once I stopped using the outermost USB3 port, I had no more problems with auto-unlock.

Mine has the USB-C ports so that's not it.

If I disable Wifi on either watch it breaks auto-unlock completely, even though it's actually using Bluetooth to actually do it. I don't understand that.

It first establishes a link via Bluetooth LE then uses Wi-Fi to determine your range.

Guys your right. I factory reseted the watch. I worked for like 5 times and then it failed again. Solution was to uncheck the autounlock feature on the mac and restart both devices. It work 2 out of 5 times now. It would be great if the autounlock feature had the same reliability as handoff now.

I'm seeing threads that mention some failings of the S4 that match some of the failings of my S5. I thought the S4 would have been the way to go until stock was deleted and they only carried the S5.

I still have my S3, and it's still much faster and more responsive than my S5, and the microphone actually works. The screen goes out when I turn my wrist away like it should, While my S5 tends to keep the screen awake (not AOD, but wide awake like you're looking at it) indefinitely unless you catch it and jiggle your wrist. I have been caught at least once with a dead battery out of nowhere until I caught mine staying full awake after a couple minutes a few times.

When auto-unlock works, it's slower--much slower with my S5 vs the S3. Also, Siri is dead slow on my S5. It's like a core on the CPU is dead.
