I just downloaded Steam and Borderlands 2 on my mac, but I have two user accounts on this Mac. With apps from the app store they are available to use from either user account. Steam is available from either account, but I have to download Borderlands 2 again to the 2nd user account, so now I have two copies on my computer it seems. Am I doing something wrong? Is there a way around this so that Steam games are available from either user account? (I use the same Steam account on both user accounts) Thanks!
