For the last week or so, my bluetooth will break after my computer goes into standby or sleep. It will work perfectly fine, but as soon as my computer goes into standby, when I bring it back up, the icon is greyed out like bluetooth is off, but I can't turn it on. Choosing "Turn Bluetooth On" does nothing, no matter how many times I try it. I read elsewhere that turning off wifi and turning it back on might kickstart it, but no luck. I also read that devices with an apostrophe in the name or just a device that got corrupted might throw things off, so I deleted all bluetooth devices. I have also reset SMC and PRAM with no improvement. Curiously, one time the computer came back from sleep and I had a squiggly line through the bluetooth icon and it said 'Bluetooth not available." I currently do this in terminal every time to get it working. sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport After I do this, bluetooth works perfectly until the next time I sleep. I have to think this is a software issue since unloading and reloading the kernel fixes things temporarily. Any suggestions before I wipe out my OSX and start from fresh?
