After booting my Mac Mini the keyboard doesn't work until I unplug it and plug it in again. It's NOT LOOSE, it just doesn't see the keyboard after boot until I plug it in again.
I've tried it in a Winblows, works fine. It's strange. I also got a pipe cleaner w. some rubbing alcohol and hit the contacts. Still does it. Next I might try some holy water! lol Thanks for the response.
