How to Unlock Mac Using Apple Watch

macOS Sierra, when released during WWDC 2016, raised many expectations from users and it has fulfilled all expectations with awesome features and updates. Among many, people have appreciated Auto Unlock feature on their Mac devices along with the latest MacBook Pro. Every time, people have to enter a password to unlock Mac.
