Two words come to mind here, "Machintosh" and "ram". In reviewing the message board here and trying to gain an insight to this community I would like to say that Adobe and Apple are good friends, and have been from the beginning. I have the same software installed on both formats, with 5 times the ram on my mac. Invariably, it runs better. (meant in a good way, I hope I didn't offend anyone). :) Rick
