Most of the unlocked discussions are with folks who have MacBooks. I've got issues with my Mac mini. At one point, I had automatic unlock with my late 2014 Mac mini and Apple Watch. It took a unpair and re-pair to get it working. However, I just went from a 6 plus to 7 plus (clean install) and am stuck at macOS trying to unlock with the watch and eventually failing and asking for my password. Don't know what to do. Suggestions?
