At a glance
Terraria has a Mac version: Steam sells it for macOS. Install it in Steam for Mac; it doesn’t need Uncork.
Terraria came out on Steam on 16 May 2011, made by Re-Logic.
What your Mac needs
Minimum macOS in the Steam requirements: 10.9.5.
Steam requirements list at least 2.5 GB of memory for Terraria; 4 GB recommended.
Allow about 0.2 GB of disk space for the Mac version.
How to play
Open Steam for Mac and install Terraria 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 Terraria from there (0.2 GB). We have not tested it ourselves.
The Windows version through Uncork needs a Mac with Apple Silicon (M1 or newer).
Terraria uses DirectX 9.0c: Uncork renders it with its built-in graphics.
