I just did the latest System software update and it was to adjust the level of the sleep light. When I restarted my iMac after, Bluetooth had completely vanished, no evidence of it ever being on my computer! What do I do? Thank goodness I had an old keyboard and mouse kicking around....
I am using the flatscreen iMac with 10.4.2
