How to Run SteamOS on Your Mac

A free, open-source app called FX Steam Launcher lets some Apple Silicon Macs run the ARM version of SteamOS in a virtual machine. It offers a way to play Windows games that no longer work on macOS, which may matter more as Apple drops support for Intel Mac applications.

The app requires macOS 15 or later and does not support Intel Macs. Users choose how much virtual disk space to allocate, install SteamOS, then log in and connect a controller; the default disk size is 64 GB. Many games worked for the author, but performance and setup varied, some titles needed tweaks, and a community compatibility list can help users check games before installing them.
