- After the upgrade, the login screen showed all my users, but it refused my password. This issue is described on Apple Support: Unable to log in to account after an upgrade install. Repairing it requires booting to single user mode (press cmd-S during boot) and then enter this non-trvial sequence of commands:
mount -uw / launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist dscl . -delete /Users/curioso AuthenticationAuthority passwd curioso
and type in twice the password that you already had.
- After the upgrade the user interface freezes of my new iMac 24 inch got very bad. I had one or two freezes before the upgrade, which was not too bad. But now the freeze seemed to happen anytime I went to the dock to unhide it. I set the dock to not hide automatically, which seems to help.
Update: dock hiding probably has nothing to do with it. I booted in safe mode, and this disables the ATI graphics card device driver.
- Quartz Composer does not seem to recognize my video card, so most screen savers do not work. Still struggling with this one.
Update: this is because I booted in safe mode, and then the graphics driver is disabled.
Update (3-nov-2007): I applied the iMac 1.3 update, but the freezes persist. The problem is clearly related to the ATI Radeon HD 2600 GPU that is used in the iMac.
Update (15-nov-2007): Freezes were fixed by the Apple iMac graphics firmware update 1.0.
