Bluetooth connection works wonders. It connects my Jawbone to my phone and allows me to use the mouse and keyboard – all done wirelessly…until it stops working.

After getting my MacBook Air several months ago, I’ve been infested with random Bluetooth disconnects that I couldn’t figure out the reasons for. The Bluetooth status would tell me that my mouse is still connected but proved otherwise when I tried to move the mouse around.

Bluetooth Connected - Not!

Just before and after disconnecting, I noticed a long list of Console error messages starting with:

E:[AppleUSBBluetoothHCIController][StartInterruptPipeRead] ClearPipeStall failed with error 0xe000404f.
E:[AppleUSBBluetoothHCIController][StartBulkPipeRead] ClearPipeStall failed with error 0xe00002ed.

After trying a number of suggestions on the Apple Support Communities, here’s what’s worked for me so far:

  • When the disconnect happens, turn off your Bluetooth device and wait for it to disconnect – you should see the following Notification

Bluetooth Connection Lost

  • The Bluetooth status will probably still be marked as ‘connected’

Bluetooth Connected - Not!

  •  Click on the Bluetooth icon and turn it off


  • From here, Restarting the computer does the trick for me. Some have reported success after just logging out of the computer instead, but it hasn’t been a consistent resolution for me.


Other methods

There are quite a few methods that people have tried and here are a few that’s reportedly worked for others but not myself.

  • Reset PRAM and NVRAM
  • Put your Mac into Suspend mode – wait – log back in
  • Deleting the Bluetooth device from the computer (System Preferences -> Bluetooth -> Select device -> Click on ‘-‘ at the bottom to delete)

Here are a few links to check out if you’re still having problems:
