We bought CS3 premium a couple months ago and have tried to use the auto update from Adobe. Unfortunately after downloading the new version of RAW the updater hangs up and never completes. It is the only CS app that does this.
It's kind of an old Mac, but it has 10.4.11 on it and enough disk space.

Adobe Camera Raw 4.2 Update (never finishes install - hangs up around 40%
Adobe Updater is a piece of ****. It only works when you are the first user created on the system and it does not work when filevault is enabled. Amazing how they can get that program so crappy. It is hard to do this wrong. Just download directly and apply the updaters by hand.
