Get yourself an old Macbook Air. AKA the one I have, a Macbook Air 1.8GHz Intel Core i5, 8 Gbs of RAM and 128 GBs SSD Storage. Costs about 350$. Best one I could find.

I second that as a mac player im using wine to run the beta but i rather give money to you for the full version.

do a linux version since its free
