MacID, a cool app by developer Kane Cheshire that lets you lock and unlock your Mac using Touch ID on your iPhone, or your passcode, is now available on the Apple Watch.
If you want to unlock your Mac right from your wrist, and own an Apple Watch, you should grab the new MacID 1.2 for iPhone, a $3.99 download from the App Store. You can even use the Apple Watch app to see what's playing on iTunes or Spotify, and start screensavers on your Mac.
