Cannot rename bluetooth device on my mac
It looks like this is bug that show only up for few users. There is no current solution, I event tried manually changing alias name in plist file but it is short term(until you connect next time).
There is more and more people that are having this issue.
In my company we use Macs mostly and I am the only one having this issue. There are already some support questions opened on apples forum: https://discussions.apple.com/thread/7904717 https://discussions.apple.com/thread/7927709
I have even spent 2 hours on phone with apple and they are saying it is not a bug XD
I bought a second hand magic keyboard A1314, which uses AA batteries.
I found the following advice on https://discussions.apple.com/thread/251116009?answerId=252423285022#252423285022
- Click on the properties of your Magic Keyboard and click on "change name".
- Remove the batteries from your keyboard, causing the connection to be disconnected (Or turn it off, according to Gal Bracha's comment)
- Type in your new name. The old name will remain but that is only for a while.
- Click "done" and put the batteries back in.
- Connect your keyboard and check the name.
(Reworded the text a bit for clarity)
I suspect this only works per machine, because I tried it on another macbook and it still had the old name. I repeated the process there and it now has a new name.
Not the perfect solution, but I have no old mac to change the name of the device with :(
I also have the same issue with my current macOS Catalina. I could not change the name of my Magic Mouse. Tried resetting with debug mode, turn on and off, delete bluetooth.plist.
Then I tried to connect the same Magic Mouse to my MacBook Pro running on macOS El Capitan, and voila... I could rename it without a problem.
So, it's definitely a bug with the macOS. Not sure since which macOS version the bug existed. But I know for sure that it is okay with macOS El Capitan, and it's not okay with macOS Catalina.
But it might also be a bug combined with the hardware
