Friday before I left work I kicked off the upgrade to Mac OS 10.6.3 on the MacBook Pro (MBP)  I use at work. I’d already upgrade my personal MacBook at home (that I got a deal on at MicroCenter) and I didn’t have any observeable problems or issues and I was confident that I could upgrade and not bork my work environment.

When I arrived back into work on Monday it looked like the upgrade had completed. I logged into the MBP and  my Bluetooth MagicMouse wasn’t working, and all  bluetooth settings were unavailable and grayed out (both on the status bar, and in System Preferences).

I figured something had gotten out of sync during the upgrade and I thought a reboot would fix the problem. Rebooting didn’t fix the problem, but manually reinstalling the upgrade did solve the problem and Bluetooth is active and settings are accessible.

However, when I tried to sync with my phone, a Sony Ericsson C902, the connection keeps dropping. So Bluetooth in 10.6.3 might be a bit flaky.
