How to Unlock Mac with Apple Watch
Mac users with an Apple Watch can unlock their Mac by simply wearing their watch, thereby bypassing the need to enter a password at the boot and login screens. This great feature makes logging onto and unlocking a Mac remarkably easy and quite fast for Apple Watch wearers, but you’ll have to enable it first.
Before enabling the ability to automatically unlock a Mac with an Apple Watch, you’ll need to meet a few simple requirements; you will need a Mac running Mac OS Sierra 10.12 or newer, you will need an Apple Watch running WatchOS 3 or newer, and the Mac must be a mid-2013 or later model. Aside from that, be sure the Mac and Apple Watch are using the same iCloud Apple ID, have two-factor authentication enabled for Apple ID, and have Bluetooth and wi-fi enabled.
How to Enable Unlock Mac with Apple Watch
Be sure you meet the aforementioned requirements before proceeding to enable this feature in Mac OS:
- Be wearing your Apple Watch if you are not already
- In Mac OS, pull down the Apple menu and choose “System Preferences” and then go to “Security & Privacy”
- Go to the “General” tab and then check the box for “Allow your Apple watch to unlock your Mac”
- Enter the password to the Mac to enable the feature, then wait a moment for the automatic unlock with Apple Watch ability to activate
Done! Once the “Turning on…” indicator text within the preference panel goes away the feature is enabled and you are ready to use Apple Watch to unlock the Mac.
You can immediately try this feature on your Mac to make sure it’s working. For a laptop simply close the lid on the MacBook to make it sleep, then wait a moment and open the lid again, the regular login screen will appear but in a moment it will disappear as long as you are wearing your Apple Watch – there is no longer any need to enter a password to get passed the lock screen on the Mac, it will automatically authenticate with the Apple Watch instead. Both Apple Watch and the Mac will show a message on their respective screens demonstrating the feature is unlocking the Mac.
This works quite well and is very smooth, and it makes for yet another great reason to have an Apple Watch.
Note if you are not wearing your Apple Watch, or the Apple Watch is not unlocked by entering the devices passcode, the Mac will not automatically login. Instead, the Mac will require a password to login and unlock as usual.
Unlock with Apple Watch Not Working? Troubleshooting Tips
First, be sure you have a Mac that is compatible with the automatic Apple Watch unlocking feature. Any hardware from mid-2013 onward should work fine.
Next, be sure the Mac has Mac OS 10.12 or newer installed.
Additionally, the Apple Watch must be running WatchOS 3 or newer.
Having the same Apple ID and iCloud login for both devices, along with two-factor authentication enabled for that ID is also required.
Enabling Bluetooth and wi-fi are necessary on both devices, if one is disabled the feature will not work at all.
You’ll need to be wearing the Apple Watch and have it unlocked in order for this to work. You’ll also need the Apple Watch in close proximity of the Mac, you can’t unlock a Mac that is in another room for example.
- Be sure wi-fi and Bluetooth enabled
- Update system software on MacOS and WatchOS
- Restart the Apple Watch, and restart the Mac, then try again
- Disable the unlock with Apple Watch feature on the Mac, wait a moment, then re-enable the feature in Mac OS, then try again
The most common reasons the Apple Watch is not automatically unlocking a Mac is a discrepancy in requirements and what is set on the devices. Typically this means something like Bluetooth is off on the Mac, or the OS is not updated to a modern version, or Two-factor authentication is not enabled, or the Apple Watch is not unlocked from its pincode, etc. Thus, review the above information and try the troubleshooting steps, you’ll likely get the feature working in no time.
