Borderlands 2

Cross-Platform

Because somebody decided not to update the mac version of BL2, you need to downgrade the PC version for cross-platform play to work.

  1. Grab the downgrade files from here.

  2. Overwrite the contents of %ProgramFiles(x86)%/Steam/steamapps/common/Borderlands 2 (or %ProgramFiles%/Steam/steamapps/common/Borderlands 2 on a 32-bit OS).

  3. Open ../../appmanifest_49520.acf and change the value of StateFlags to 4.
