I think I've followed everything correctly but CDLC will still not be recognized. Took some doing in steam to even show Cherub Rock and other DLC after buying the game on this platform(I have it as well on XBONE but wanted access to CustomsForge so got it on Mac too.) I've changed Mac Patch files to read and write(all 3), I've done all the installation and placed 2 m.Psarc files in my DLC folder, which I've dragged to desktop for easy access. I can see the other DLC files in there and they look different than my m.psarc files. Mine look like a sheet of paper with a folded corner. Others look like an executable file(black screen with exec in it). Both read as a "document" but I can see no other discernable difference. I'm not sure what I'm missing.
