I'm wondering if anyone has a suggestion for clearing this problem that cropped up recently. I was away on business last week and disconnected my iMac and stored it in my basement because my office was in the process of being painted. Upon returning and getting everything connected I have observed that every time my early 2009 iMac boots up, I see a message that the Bluetooth Manager is looking for a keyboard because no keyboard is detected. After about 15 seconds a 2nd notification pops up that the keyboard has been found and the bluetooth manager can close. This is annoying to say the least. The keyboard I have is the standard WIRED one that came with the iMac. Does anyone have thoughts on this? Is there some way to clear out the system's knowledge of the keyboard location so that this stops occurring? Thanks.
