-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 For what it is worth (I'm fairly confident that indeed this is not the cause of the problem you are seeing, but better checking than missing the point):
The current MacBook Pro also have two GPU, one integrated in the chipset and a more powerful dedicated one. By default only the chipset integrated one is on (to save on power consumption), so if you're doing graphics it is worth going in "system preference" -> "energy saver" and at the top preference window check that "Graphics" is set to "Higher performance"... A bummer is that it is currently necessary to restart one's session to go from one setting to the other, and I'm not 100% sure that this setting is preserved upon reboot of the machine...
