Fallout: easy(ish) installation on macOS (Apple Silicon)

Having just finished the TV series of the same title, I figured it would be a good time to replay one of my favorite games from my teenage years: Fallout, but I don't own a Windows computer and the game was never released for macOS. Fortunately, the excellent Fallout Community Edition project faithfully reimplements the game, although the installation instructions for macOS are, for the moment, a mess. While those instructions are being ironed out in the issue tracker, I'm hoping this guide can help anyone who just wants to play the game on a Mac with minimal fuss.

NOTE: This guide still requires you to purchase the game. Presently it's going for $10 on Steam (and $2.99 on GOG, but I couldn't get the GOG artifacts working on macOS).


  1. Install the Steam macOS client install steam

  2. From the terminal, run Steam with the -console flag: /Applications/ -console. This will give you a new CONSOLE tab at the top beside the STORE, LIBRARY, etc tabs.

    $ /Applications/ -console

  3. In the CONSOLE tab of the Steam client, run download_depot 38400 384091. After a moment, the console should report that the download has begun and when it completes, it will print the download path. Optionally move or copy the depot directory somewhere more accessible, like ~/Games/Fallout download game from steam

  4. Download the Fallout CE installer (the macOS .dmg file) from the Fallout CE releases page if you haven't already. Running the installer should open a Finder window with just the Fallout Community Edition app; drag that into your depot directory (e.g., ~/Games/Fallout). drag fallout-ce to depot

  5. Open your depot directory in a Finder window and double-click the Fallout Community Edition application to start the game. fallout

I was able to piece this together thanks largely to this comment on r/macgaming. That's probably a good place to look for more general advice or help with playing games on macOS.

  1. I got the app ID and depot IDs from the Fallout page on The app ID was 38400 and the English language depot ID was 38409--you can find more depots on the 'depots' tab on the left of that page)
