Hey all, I installed 10.6.7 as soon as I heard the news this morning. Thinking that nothing could go wrong as I haven't had any problems that people have posted about. Anyway, I've been using a Griffin Video Display Converter perfectly under the 10.6.6 that came with my Early 2011 15" 2.2 MBP. After the update, plugging in the cable changes the display as normal, but the external screen (Samsung P2350) doesn't pick it up and stays blank. VNC confirms that extended mode is indeed on. I'm going to go through the paces (reset PRAM/SMC etc) to see if anything will help. Anyone else having problems with third-party display connectors?
