I have been keenly awaiting this release, but I will chain myself to the mast to avoid installing it until at least a week has passed. This is not a minor update. I'll let my good friend Andrew do some testing first ... (Andy prides himself on installing every Apple OS and product update without hesitation ...)
Note one fix is to completely disable Quartz Extreme:
Disables Quartz 2D Extreme—Quartz 2D Extreme is not a supported feature in Tiger, and re-enabling it may lead to video redraw issues or kernel panics.Quartz extreme was a major Tiger pre-release feature. I hope this doesn't mean it's been bumped completely out of Tiger! A bitter pill indeed.
