I'm also a Mac user and my Epi program primarily used SAS. I was commuting quite a ways for my degree so using the schools computer lab wasn't an option.
What I wound up doing was downloading VMWare Fusion and partitioning my hard drive, running Windows on the partitioned drive with SAS. It was easy to set up as I'm not super computer savy. It worked well at first but SAS takes up the ton of space along with the partitioned drive so as I used my laptop more space became an issue and my laptop fan would be going nuts. But I think you have a decent amount of memory, probably 75-100 gigs just for the partitioned drive, SAS, and all your programs, you can do okay.
I used the Mac side for everything else. It's an 8 year old laptop, only major issue I had was the battery bit the dust on year 6.
I've run R and R studio on my Mac a bit and haven't noticed any issues or heard of any. Love R. Seems most of my grad classmates used Macs and the rest used Asus computers.
Part way through I stopped bringing my mac and mostly just used my ipad at school and the Mac for assigments at home.
