I have a 2008 mac pro with the aluminum bluetooth wireless keyboard. Everythings been fine for over a year now and then after working in windows today and rebooting into OSX my keyboard wouldn't respond. What I've tried/observations: - I know the hardware is working because it still works in windows and for selecting the boot partition (holding option upon start). - I tried a few restarts and reset the keyboard - The bluetooth icon isn't showing up at all on my system preferences or my menu bar. If I check "show bluetooth status in the menu bar" it appears and disappears immediately and then unchecks its dialog box - If I search for bluetooth in my system preferences, I can find the main bluetooth dialog to check the status of existing devices and add new devices. If I try and add a new device I get the message "No bluetooth hardware found: in order to use this application, you must have a bluetooth module. Please verify that your bluetooth hardware is properly attatched to the computer." I don't believe that this is a hardware issue because of the hardwares functioning in windows/boot, although I don't have any ideas for a solution - Under "about this mac" bluetooth is listed under the hardware contents but if selected displays the message "no information found" Thanks all for looking, any thoughts would be much appreciated.
