While battling iMac M1 forgets it has a TouchID key I found Reset Mac OS X Bluetooth service? which reveals a helpful strategy to reset not simply the Bluetooth service from throughout the Mac, but additionally a way, by holding Shift ⇧ Choose ⌥ while opening the Bluetooth menu, to reset related {hardware} to manufacturing unit circumstances.
Sadly, this convenient debug menu is gone in current macOS, to get replaced by this simplified model.
Does anybody know the place it went?
Previous to it being on this menu, it was within the Xcode toolkit. I haven’t got or use Xcode to have the ability to rapidly discover it if that is the place it is gone, however I am fairly prepared to obtain/set up needed components if that is what’s required.
