Just lucky, I guess. The main reason I’ve seen the spinning rainbow pizza of time is memory. If I'm using all my RAM and the machine has to page to the hard drive to free up some space, I'll often see the rainbow pizza. This paging can be greatly slowed by a nearly full hard drive causing the swap file to be fragmented. I hardly ever let my boot drive get more than 80% full. If you run a directory repair tool on the boot drive, you must quit all the programs causing the memory pressure. So, is it the directory repair or the lack of memory pressure that makes the rainbow pizza scarcer? I don’t know the answer. L^2
