At a glance
SOMA has a Mac version: Steam sells it for macOS. The Mac requirements list only Intel: on Apple Silicon Rosetta 2 runs it, and old Mac versions sometimes do not start on current macOS. Try it in Steam for Mac first.
SOMA came out on Steam on 21 September 2015, made by Frictional Games.
What your Mac needs
The Mac requirements list only Intel.
Minimum macOS in the Steam requirements: 10.9.
Steam requirements list at least 4 GB of memory for SOMA; 8 GB recommended.
Allow about 25 GB of disk space for the Mac version.
How to play
Open Steam for Mac and install SOMA as usual.
If the Mac version will not start, you can install the Windows version through Uncork: download Uncork, sign in to Steam and install SOMA from there (25 GB). We have not tested it ourselves.
The Windows version through Uncork needs a Mac with Apple Silicon (M1 or newer).
SOMA uses OpenGL 3.3: Uncork renders it with its built-in graphics.
