Mar 18, 2013 4:13 AM in response to Grant Bennet-Alderby SSeed1994,Thank you, that's a relief! Does that mean it's likely to be a problem with my external bluetooth device instead?

Mar 18, 2013 7:02 AM in response to SSeed1994by Grant Bennet-Alder,Those are ordinary kernel panic (access to non-existent memory) that occurred in routines called by Bluetooth Audio drivers in the kernel. You have no non-Apple kernel extensions present.
Candidate causes are:
* external Bluetooth devices sending junk
* corrupted Mac OS X
* RAM Memory errors

Mar 18, 2013 1:34 PM in response to Grant Bennet-Alderby SSeed1994,Thanks for your help, I'm hoping that it's just a problem with my bluetooth device rather than a corrupted Mac OS X, but is there any way of determining definitively? Also, I had a fourth kernel panic today, again when I was turning my bluetooth device off. The panic report is shown below, although I imagine it is the same problem as before.
