Question: I'M SIGNED OUT, KEYBOARD NOT CONNECTING TO BLUETOOTH
I'M SIGNED OUT, and KEYBOARD NOT CONNECTING TO BLUETOOTH.
ANSWER: I found the solution. i turned off the mac and unplugged it. when i turned back on it asked me to press some numbers to reconnect the keyboard to bluetooth. and it worked without logging into Mac. Make sure Keyboard is on or light is blinking.
