Missing Bluetooth module?
Mac Mini (3.1 - mid 2009) wouldn't recognize wireless keyboard today - am now missing any Bluetooth icon or options in System Preferences - Internet & Wireless. Bluetooth under Hardware in system profiler just says "no information found", and bluetooth icon in menu bar says "Bluetooth: Not available". Bluetooth firmware update says "your computer's bluetooth firmware is up-to-date". Bluetooth file exchange error says "in order to use this application, you must have a Bluetooth module..." This worked a week ago (I've been out of town). Any suggestions how I re-install Bluetooth?
Mac Mini 3.1, Mac OS X (10.6.5)
