Unable to rename Magic Keyboard name
There is a 2017 thread with the same issue, relating to OSX Sierra. The suggested procedures in that thread did not solve the problem. I have the same issue with an older Magic Keyboard (the style that takes two AA batteries). The old thread appears closed so I started a new one.
2018 MacMini, OS 10.15.4 latest update April 11, 2020.
Renaming procedure appears to work initially, but as soon as I close Bluetooth preferences, the keyboard name reverts to the old name. Tried the Debug / Factory reset all BT devices, to no avail. Connected the keyboard to a different Mac, not any better. This is more an annoyance, but I would like to get this resolved.
TIA for any help from the Community.
