So, I updated to 10.10.2 last night on my 13" mid-2010 MacBook Pro, and now my MacBook says that Bluetooth is not available, and it says "no information available" under the Bluetooth section of the System Profiler. Has this happened to anyone else? How can I fix this? I've already tried restarting twice. ---------- Never mind - an SMC Reset fixed the problem. Still... ugh.
