[QUOTE="mokjok, post: 639377, member: 25972"] [b]The plot thickens[/b] Sorry to re-post to my own thread, but maybe someone can shed light on all of this. The video display issue has seemingly vanished after a power interruption and subsequent reboot. Is it possible that this has reset the PMU, and the original problem was caused by the video card not correctly being activated? However, the same reboot now has Bluetooth working again, and my Console filled with the 'non-mach-based version' error messages. I've attached a screenshot of the Console as an example. What I don't understand is, why do I get these error messages when Bluetooth is working, but no error messages when Bluetooth is not working? The only thing I can think of is that there is some error in the Bluetooth component of OS X that sometimes causes it to work with lots of errors but other times to not work at all. If anyone has any ideas about how to actually FIX this, I'd be really grateful! [ATTACH=full]8520[/ATTACH] [/QUOTE]
