Hi, I just installed the 1.1 update on my iMac and since then I have freezes when the machine awakes. It is only the graphics because I can shutdown the machine using the remote control. The cursor still works but there are some distortions in the graphics. It might also relate to the fact that I tried to run the OpenGL profiler which asked for some changes which I did not make and then crashed. Does anyone else have the same problem? It is only for wake ups, not cold starts or restarts, yet. Reverting to 1.0 For those that have as many problems with the update like I did, here is a way to restore your old driver. I guarantee for nothing. Download the 1.0 update from: http://www.fileavenue.net/index.php?...s&cat=1&pl=mac Download Pacifist if you do not yet have it installed: http://www.charlessoft.com/ Drag the update package onto pacifist. Select the root named: Contents of iMacSoftwareUpdate1.0.pkg. Press install. It will override all files that have been updated with 1.1. Since then I did not have any further trouble. Reset the PRAM if some problems remain.
