Can't rename Apple Keyboard or Magic Mouse -Solved-

Amigos tuve problemas para cambiar el nombre de mi Magic Mouse 1 en Catalina OS, tiene un BUG en esa Version de SO, tuve que ir a mi MacMini que tiene HighSierra y desde ahí renombrar mi Mouse, luego al volver a enlazarlo a dispositivo con Catalina OS toma el nombre que definí en HighSierra, Saludos espero les sirva.

Nice work-around! I verified it works.

Hopefully they can fix it in the next update, since this work-around works, it shouldn't be that hard.

Now, if they can get the iSight mic to work again.....

Thanks

Thank you so much!! I had to connect a mouse in order to select rename (for some reason I couldn't tab to it) and had to take the batteries out of the trackpad, as it wouldn't disconnect.... but in the end I had success!!

Yes, I too cannot rename my mouse or keyboard. Seems it should be an easy fix, but Catalina certainly has its quirks.

Anybody have an answer? I don't have availability to an older Mac running Leopard or El Capitan.

Same problem here but I was able to solve it.

Got a used Magic Mouse 1 under the name of its original owner. Tried renaming it in BT setting running Catalina 10.15.6 was successful in the BT setting but under:

About This Mac - Overview - System Report - Hardware - Bluetooth, name remains the same from the old owner. Opening the BT again, mouse goes back to original name.

Connected the mouse instead to my other MacBook running Snow Leopard, was detected and still with original owners' name. Renamed it under System Preferences - Mouse - Setup Bluetooth Mouse, Right Click on the Mouse - Rename.....

Successfully renamed the Magic Mouse 1.

Reconnected it again to OS Catalina, new name appeared. Tried renaming it again in Catalina, no success.

Solution: Renaming the Magic Mouse 1 on older OS X, Snow Leopard works.... - Partly SOLVED (since renaming should work in Catalina) sorry for those who do not have access to older OS..... :-(

Rafasiqueira's solution is the only one so far that works perfectly! Not sure why renaming it after a power off works, but it does!

The factory reset solution did not work for me. It reset my mouse, but it still had the same (customized) name as before the factory reset when reconnected.

This worked for me too! I was lucky enough to have an old MacBook Pro (early 2011) hanging around with macOS High Sierra 10.13.6. After pairing the mouse with that old computer I was able to rename it in the Bluetooth Preferences screen and the name change actually persisted.

This solution actually works you will probably need a laptop Macbook in order to do this fix because you have to be able to click on rename after you turn off the mouse. I used my MacBook Pro in order to rename it.

Well, after all these Catalina bug fixes, and they still can't fix it, don't expect it to still work on the actual release once it's out of beta.

The mic is still dead on my iSight too. Worked in Mojave, dead in Catalina....

No, you do not need a laptop. I verified that this work-around does work on a desktop.

I did it on my Mac Pro.

Only the MagicMouse. I don't have an Apple wireless keyboard in use right now.

Hopefully Apple will eventually fix it, so we don't have to use this work-around, but it's great that someone was able to figure it out.

The earlier reply of opening the "right click" menu while turning off the device didn't work, and I don't have a suitable device handy running an older version of MacOS. So I tried this one. Here are my results:

A. It made all my older battery-powered Apple Bluetooth devices no longer able to connect (they show up in the list and the "connect" option is there but neither keyboard nor mouse will connect now).

B. It did not accomplish the task of renaming the keyboard.

However, after about 5 minutes, I went back up to the Bluetooth menu and found that the missing "rename" option is now in the menu for these devices!

So the only downer here is that I can no longer use my older non-rechargeable devices, and y'all need to be aware. If you don't have rechargeable (or wired), you'll be out of luck here! Careful.

I'd like to improve upon the solution's instructions

1 Connect Device

2 Go to settings, right click on device, don't click the menu, leave it open

3 Turn off device

4 Select "rename" in the still open right click menu

5 rename the device (type the new name with your macbook's built-in keyboard or alternate keyboard, if renaming a wireless keyboard) and close the pop up by clicking the Rename button (with a 2nd mouse or trackpad, if renaming a magic mouse).

6 Turn device back on and connect

Thanks a lot. This worked like a charm. I tried it normally so many times but when I did this, it got sorted from the first go.

I just had to turn off my mouse before clicking rename and actually renaming my mouse.

This worked for me. However, on step 6. when I connected, it showed the old name. I was just about ready to fire up an old MacBook for the other method, when I exited system preferences then called it up again, voila! my mouse now has the new name. Finally. Thank you Rafasiqueira

Thank you, thank you, thank you rafasiqueira!! I'm on Catalina and gave up, months ago, on changing the name of the secondhand Magic Mouse I have. Decided to give it another go and found this post. So happy I did :) For anyone having the same issue, definitely try rafasiqueira's method!
