After searching the internet for anyone with a simiar problem, I was unable to find a definitive answer. I use an external monitor with my MacBook Unibody, along with a Bluetooth mouse and keyboard. The Bluetooth has been unstable for a while, with the mouse lagging all the time and sometimes not even connecting, but now my MacBook does not even recognize that it has a Bluetooth module at all. I can't select the Bluetooth pane in System Preferences, and attempting to open it from Spotlight warns me that I do not have any Bluetooth devices installed. Also, under About This Mac, there is nothing under Bluetooth. Any ideas? It's been this way since a restart today, and I have since tried restarting the MacBook multiple times. I would like to avoid bringing my Mac to the shop, because the only local shop is an authorized reseller, and I'm going out of state on Monday for the week and would like to have my MacBook with me.
