Auto unlock: unintended behavior
I have enabled Auto Unlock on MacOS Sierra. I assume that Auto Unlock is intended to work as follows: I open the lid of my MacBook, and my Apple Watch (running WatchOS 3) unlocks it wirelessly.
However, if I am in the vicinity of the Mac, my Apple Watch unlocks the Mac even when the lid is closed and the system is sleeping. In fact, the Watch unlocks my Mac over and over again, with a frequency of more or less once every minute, when the Mac is sleeping. That is both annoying, since every time I get a notification on my Watch, and it wakes up the computer with the lid closed, which is not supposed to happen.
If this is how it works in general, Auto Unlock is very poorly implemented.
