One macOS Sierra feature that like the most at WWDC 2016 was “Auto Unlock.” Done with entering passwords every time I have to unlock my Mac, I had been waiting for this smart feature to arrive for a long time.

Fortunately, Auto-Unlock has gone live with macOS Sierra beta 2. Excited by this elegant feature, I rushed to give it a quick try. And from what I have experienced, I can say that it has really impressed a person like me who can’t help using Mac.

Step #6. Up next, lock your Mac and try to wake it wearing your smartwatch.

If you try to unlock your Mac without wearing your Apple Watch, password screen will appear as usual.

If you use a desktop Mac, Auto Unlock will be invoked just by waking the machine.

You will need to press the Cancel button to invoke Auto Unlock if the Mac is already awake.
