So I just noticed that my PowerBook no longer realizes that it has a Bluetooth module installed. I get a little “broken B” icon in the menu bar, and when I open the menu it says in greyed-out text “Bluetooth: Not Available”. I fired up the Bluetooth setup assistant and it said it couldn’t find any Bluetooth hardware either. The only two noteworthy things that have happened recently are I installed the latest Apple security update, and I let the laptop drain itself of power in order to reset the power level calibration. I haven’t ever run a Bluetooth firmware update, so that doesn’t seem like it’s the problem (unless of course the problem is that the security update requires a firmware update, but nobody said anything about that).
Oh, and no, I don’t have a Bluetooth device with which I can test the Mac’s module. It still bothers me that the computer seems to have lost some of its hardware. I’d sort of like to have it found again. Has anyone else seen this problem, and if you fixed it, how did you fix it?
Update: thanks to Daniel Bergey, whose friends just recently moved to my home state, I’ve solved the problem and the Bluetooth icon is back to normal. See the comments for details and a link to a description of the procedure I followed.
