Hi, I purchased the game from the MAC App Store and completed the true vault hunter mode and I am at level 50. I would like to buy the package that allows me to play up to level 61 and/or buy the season pass. I do not see that option at the App Store and was wondering how I can purchase the additional games and unlock UVHM. Thanks, I do have the option to buy the "in app" extra missions but they do not include the up to level 61 option as far as I can tell. Dave Ps I am playing on a 2012 IMac in osx.
