I cannot see "Allow your Apple Watch to Unlock Your Mac"

I too did not have/see the option in Preferences-->Security and Privacy to "Allow your Apple Watch to unlock your Mac." So, I signed out of iCloud on my MAC (not my iPhone as I would then have had to activate all my Apple Pay credit cards again). Sadly, doing just this did not work.

Now, I am aware that one of the reasons why the option to allow my Apple Watch to unlock my Mac does not appear is because your Watch is not paired with your iPhone. But, I knew my watch WAS paired with my iPhone and I did NOT want to unpair and repair b/c that is a huge hassle. By the way, when you unpair and repair I believe the Health and Fitness app treats the Watch as a new device and it no longer retains your exercise data from the Watch before unpairing. That is a BUMMER. So, beware of unpairing and repairing if you actively use your Watch for fitness.

ANYWAY...what finally did work, (after signing out and then back into iCloud on my Mac) was to do a HARD reset of my Watch. Simultaneously hold down the digital crown and side button. Keep holding both down until the Watch screen goes black. KEEP HOLDING DOWN. Wait for the white Apple logo to appear. Let go. It will take a while for the Watch to reboot. Cook a turkey or something to pass the time. But, when my Watch did reboot I received a message on my Mac that it was connected to a "new" Apple Watch. I then went to preferences-->Security and Privacy and what to my wondering eyes should appear but the checkbox with the option to "Allow your Apple Watch to unlock your Mac."

Maybe this will work for some others. Good luck.

Well, darn! Do you live near an Apple Store to avail yourself of a Genius?

I have the same issue using: WatchOS 4.0, MacBook Air (13-inch, Early 2015), macOS Sierra 10.12.6.

• Mac has both Bluetooth and Wi-Fi turned on.
• using two-factor authentication.
• Mac and Apple Watch are signed in to iCloud with the same Apple ID.
• Your Apple Watch is using a passcode.

I do not see the "

Allow your Apple Watch to Unlock Your Mac" check box.

Mr Luigi - yes I did. FYI the unlock works flawlessly on my iMac (Retina 5K, 27-inch, Late 2015). I only have this issue on my MacBook Air.

I think is because we don't have the right model of Mac. I have an early Macbook Pro 2013.
If you go to the apple logo and you open System Report, then you go to wifi in the left column, if you don't see Apple Watch Unlock Supported, then means it doesn't support it.

I wonder if there is a way around it, but so far I didn't find a valid solution.

Hi DJ Droogie, Just curious, did you do a HARD reset of your Apple Watch as I suggest in my post above?

To initiate a Hard Reset:

• Simultaneously hold down the digital crown and side button.
• Keep holding both down until the Watch screen goes black.
• KEEP HOLDING DOWN.
• Wait for the white Apple logo to appear.
• Let go.

Hi

The feature is available for Mac models from mid-2013 or later:

Automatically unlock your Mac with your Apple Watch - Apple Support

Check the supported Mac model here: macOS Sierra: Unlock your Mac with Apple Watch

Does your Mac meet all the requirements listed in Automatically unlock your Mac with your Apple Watch - Apple Support ?

You need to have set up two-factor authentication, not the older two-step authentication - that is easily confused.

Your mac needs to be a Mid-2013 or newer mac, your Apple Watch is using a passcode..

Check that:

• Your Mac has both Bluetooth and Wi-Fi turned on.
• Your Apple ID is using two-factor authentication.

  Note, however, that having two-step verification set up currently would not prevent the unlocking option from being displayed.

• Your Mac and Apple Watch are signed in to iCloud with the same Apple ID.
  • On your Mac, choose Apple menu () > System Preferences, then click iCloud.
  • On your iPhone, open the Apple Watch app, then go to General > Apple ID.
• Your Apple Watch is using a passcode.

  On your iPhone, open the Apple Watch app, then tap Passcode.

I have same issue. After updating to macOS Sierra i went to security and privacy and the option was there. I ticked it and was told i had to move to two factor authentication. Which I did- the second I did that the option to use watch disappeared. This was on a 2015 MBP. Then I went home to my imac (late 2013) updated to Sierra and everything was set up the way it should be and the option is not there either.

I have signed out of iCloud. I have made sure my watch is all configured properly. When i go to <Manage Apple ID (dot com)> i can see that the settings are correct as well as icloud system prefs i can see all my devices.

I'm having this exact problem too
