I am having an issue every so often with my Magic Keyboard. Every once in awhile, it will act like a key is stuck. If I turn off the keyboard and turn it back on, it doesn't work at that point. If I reboot the computer with the keyboard turned on, it will reboot to the FileVault password recovery. If I turn the keyboard off before rebooting, it will reboot normally, then I can turn the keyboard on and it will work properly. That is, until the next time it does it. It's really sporatic when the problem occurs, but when it does, it's a pain. Has anyone esle experienced this?
