Unlocking a Mac with Apple Watch 5

sagaman04 wrote:

Unlocking works following an upgrade of the Mac and/or of the Watch. There are several users on our Mac. Unlocking my user account with the Watch stops working once another user has logged in which usually happens either before or after one of my own sessions. For instance, my Watch automatically upgraded overnight recently. Unlocking started working again after a period when it failed to work. Once my partner had logged into her account and logged out again unlocking of my account stopped working. Should this happen?

If not, is there anything I can do about it short of buying another Mac for my own exclusive use.

Sounds like a bug in the macOS.

This sounds like a good idea.
