Hi, I just bought a Macbook pro 15inch mid 2015 with AMD gpu, I've always been a WIndows user, and now I've switched to Mac mainly beacuse I need a portable but productive machine for the adobe suite. I am not a gamer, however, there are 2 games that I used to play sometimes on my windows pc : pes6 and GTA san andreas (both with mods). Since I would like to still play with them sometimes, I was thinking about installing a windows virtual machine (xp or 7) on my macbook. but I didn't want to waste my ssd memeory (also beacasue these 2 games don't require any particular fast memory) so I was thinking about installing the virtual machine on an external SD card (maybe a 64/128gb one) and put it on my macbook just when I want to play. do you think it's possibile? has someone tried it? thank you!
