I've downloaded the source and can successfully compile it on MacOS Sequoia. I modified the Font.cpp for vgui and was able to make a menu_amd54.dylib. Honestly, I'm in the dark as to how to implement this so TFC will run on MacOS 64bit. I tried just copying that dll into the dll folder, but when I run the game, I can change to TFC but have no option for New Game or Multiplayer/Create game.
I'm happy to work on making this work in any way I can. My goal is to play "The Hunted" on MacOS 64bit. It "works" using wine but super clunky and sometimes just show a black screen. I'm more interested in working to get it to run native.
