The Bluetooth on my late 2008 Unibody MacBook suddenly stopped working a few days ago. My mouse is the only thing I use Bluetooth for, and it works perfectly with my iMac - so it's not the mouse. All looks fine - no error messages and that. It can find the mouse, but it either wont connect, or it will say its connected, but nothing works. This is the case for both Mac and Windows on Bootcamp. I first reset the PRAM, and it solved it. When I booted it up the next time I used it, it went back to the way it was. I took it to the Apple store and the Genius hooked my MacBook to one of their portable HD's and the Bluetooth worked instantly. Back on my hard drive they then deleted com.apple.bluetooth.plist and restarted, which solved the problem. When I got home and turned it back on, it again went back to the way it was. I was wondering if anyone else knows of this problem and a possible fix. I've looked around and I can't find any problems like mine. I'm also thinking of seeing if a full wipe and reload works before going back to Apple. Any thoughts?
