if you are looking to buy a brand new laptop, then anything will work. they do not require you to buy a PC. the D12 class did have 2 dental programs to load on our computers and there was a separate mac version. but a count was taken at the beginning of school to see how many PC and mac versions they had to order. i do not think they will continue this for your class because its very expensive and most of the people in our class agreed that although it was an awesome program, it was just too much info, too expensive, and we didn't have the time to run through all of its capabilities.
some of our professors teach off their mac's so you will def be fine if you decide to go that route.
