I was finally able to afford a second hand cinema display, but when it arrived there was no power cord or install disc. My fault for not asking if it included the power supply, (that's a whole other search I have to do). I've spent the day searching for a download of the install disc, but can't find it anywhere on the web or Apple support. Maybe I've been using the wrong search tags, but I'm ready to give up. Anyone have any suggestions where I can get it?
