My 27″ iMac has been having some very strange bluetooth problems lately. As mentioned in a recent blog post, all bluetooth devices were unavailable according to the operating system. Reboots didn’t fix the problem. Checking through the console logs turned up messages about the bluetooth drivers not working properly. Fortunately I had a USB keyboard so I was able to make a full backup of the system before scheduling an appointment with the genius at the Apple Store.
Now it has been a couple weeks and I have the machine back and Apple didn’t find anything wrong. In fact, they say the bluetooth works fine. I turned everything on and it works fine here too. I had a hunch that this might be the case. Last week my 13″ MBP had the exact same issue. No bluetooth devices would work with it. In this case a full reboot did correct the problem.
So, what bluetooth devices do I have, and which one is misbehaving and causing all of these problems? I don’t know for sure, but I suspect either the new iPhone 4 or the Plantronics Bluetooth Headset I have. The Apple Bluetooth Keyboard and Magic Mouse seem to be working fine. I have noticed other issues with the bluetooth on the iPhone 4 when it syncs with the Alpine IWA-505 head unit in my truck so my money is on the iPhone 4 being the cause in all of these bluetooth problems. Time will tell.
