At a glance
We tested ASTRONEER on a Mac ourselves: 5 October 2026, MacBook Pro 14″ with M3 Pro, Uncork 1.0.5. The 3D intro scene renders correctly; not played further.
ASTRONEER came out on Steam on 5 February 2019, made by System Era Softworks.
Will ASTRONEER run on a Mac?
Players ran ASTRONEER on Apple Silicon Macs through the same kind of compatibility layer Uncork uses:
| Date | Mac | macOS | Rating | Played |
|---|---|---|---|---|
| 17 Oct 2026 | M4 | 26.7.1 | 5 / 5 | 13 min |
Graphics in the reports: D3DMetal.
What your Mac needs
You need a Mac with Apple Silicon (M1 or newer): Uncork does not run on Intel Macs.
Steam requirements list at least 4 GB of memory for ASTRONEER; 8 GB recommended.
Any Apple Silicon Mac has enough memory for the listed minimum.
Allow about 2 GB for the game and another 5 GB for Uncork and Steam (their size in our fresh-install check in October 2026).
ASTRONEER uses DirectX 11: Uncork renders it with D3DMetal.
