Hi, I am a fan of the game Borderlands. I have already completed the main story line of the game. I would really like to play the add-ons the DLC levels. The problem is that I do not know how to istall them on my mac. I have the Borderlands Data.dmg and the Borderlands Add-On.dmg but i do not know how to run the Add-On.dmg. Could someone help me and write me a way how to istall or run the DLC levels (Add-On.dmg file). Because the game works perfectly and this is the only problem. I am a novice with mac, so please if you will write me a way how to do it, be simple . Thank you very much !
