    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.

    Right now your Bluetooth hardware, for whatever reason is not detected by the system.
    Try a PRAM reset:
    Try an SMC reset:

    Both are hardware resets of various levels.

    If that doesn't help, I would suggest a reinstall of OS X. If you did a simple update (and you were already running Yosemite), then a reinstall would assure that everything in the system software is correctly installed.
    Since 10.7 and later OS X versions, a reinstall is pretty quick. Install to an SSD from a USB device will probably take less than about 15 minutes. Then a simple check for additional updates (there will be a couple), and you are done, likely in less than 30 minutes.

    Get the full Yosemite installer from the App Store. Don't let the installer begin the install before you backup the installer app, and make a bootable USB flash drive. There's steps available for how to do that (using some terminal commands), or, easier, is to use the DiskmakerX app that you can download.
    DiskmakerX makes a nice Yosemite installer to keep on an 8GB flash drive.

    After all that - Still no bluetooth? You will need support from Apple (and you are out of warranty, too) Likely just needs the bluetooth card...
    And, that's not as simple as it sounds. Just checked in a service manual, and the bluetooth is inside the display assembly (the clamshell) The wiring runs through the hinge area, and you can try reseating the camera connecter on the logic board, as camera/wifi/bluetooth connections all run through that connector.
    Well, I hope the PRAM reset fixes it first !
