I had to switch to a mac and infantry only works on windows right now, so do u guys have any solutions that'll make me able to play? Also i won't be able to play as much now because the Mac is in the living room.

Boot camp. It's built into your mac. Just get a copy of a windows os to install. I play on my MacBook Pro.

Go play on your cousin Mikec's computer troll

my mac is too old to run bootcamp and a don't have a copy of a windows OS. Does anyone know how to use a mac/windows parallel others than that?
