Install (macOS)
1. Download
Download TSArmsRace-macos.zip below.
2. Extract into game folder
In Steam, right-click Twilight Struggle → Manage → Browse Local Files. This opens the game folder (the Library folder is hidden by default in Finder, so this is the easiest way to find it).
Extract the zip contents into that folder. You should see libu6inject.dylib, run_bepinex_u6.sh, BepInEx/, and dotnet/ alongside TwilightStruggle.app.
3. Set Steam launch option
Right-click Twilight Struggle in Steam → Properties → General → Launch Options:
"/Users/YOUR_USERNAME/Library/Application Support/Steam/steamapps/common/Twilight Struggle/run_bepinex_u6.sh" %command%
Replace YOUR_USERNAME with your macOS username. If you're not sure, open Terminal and run whoami.
4. Play
The first launch takes 1-2 minutes while support files are generated. The game may appear frozen — don't close it.
After that, create a game and cycle through the timer options — you'll see 20 min, 30 min, 45 min, 60 min, and the rest.
Uninstall
Clear the Steam launch options. The game runs vanilla.
Windows support coming soon.
