My Apple Magic Keyboard (A1644) suddenly won't connect to Bluetooth. But when I was trying to connect via lightning cable, it did connected. When I try to forgot the keyboard over the bluetooth setting, and I try to turn on the keyboard, it's doesn't showed. Can anyone help me?
...and it turns out, by going into the Keyboard control panel, I was able to set it up again, and it works. When I get to work later this week I'll try with my Apple keyboard, but you might try that.
I have the same problem with a Ubotie keyboard; happened when I updated to 12.6.2. All my keyboards are now shown as "Connection rejected" in the Bluetooth preferences.
