On the Bluetooth menu, my new iMac has entries for the Magic Keyboard and the Mouse Mouse 2, and also for the wireless keyboard and mouse I used with my earlier iMac. I can’t find a way to delete the earlier keyboard and mouse.
There are two ways to get rid of unwanted entries.
- Open the Bluetooth system preferences pane.
- Hover over any entry and click the X that appears to the right or right-click the entry and select Remove.
- Confirm you want to remove the device.
You can also hold down the Option key and select the device from the Bluetooth menu and choose Remove; confirm as you would via the preference pane.
