Modding:Installing SMAPI on Mac
Player's guide to using mods 
This page explains how to install SMAPI (the tool which lets you use mods) on macOS.
See instructions for: Android • Linux • Steam Deck • Windows.
Install
Minimum requirements
- Newer versions of the game use NET 6.0, which is supported on macOS 10.15 Catalina or later. Unfortunately there's no way to use SMAPI on older versions of macOS (including Sierra, High Sierra, or Mohave) since it doesn't work with the compatibility branch.
Enable macOS security permissions
- Go to System Settings > Privacy and Security.
- Make sure Developer Tools is visible (see screenshot). If you don't see it, open Terminal through Spotlight and enter this command:
spctl developer-mode enable-terminal
- Click Developer Tools.
- Add Terminal to the list, and enable it (see screenshot).
- Restart your computer.
Install SMAPI
- Download the latest version of SMAPI (see a pictorial guide).
- Extract the .zip file somewhere (but not in your game folder!).
- Right-click install on Mac.command and choose open.
- Follow the on-screen instructions.¹
That's it! Just launch the game to play with mods. If you play on Steam, make sure to launch the game through the Steam client to avoid issues.
You don't need to change your Steam launch options (that's only needed on Windows).
¹To install manually instead, see instructions in the installer's readme.
Update
Just install the new version; the installer will automatically clean up previous versions.
Uninstall
- Launch the installer again (see install steps).
- When prompted, choose the uninstall option.
Troubleshooting

To fix that error:
