Unity setup for macOS

Unity is a 3d engine for game development. Installation on a Mac isn't difficult but there are a few hurdles.

  • Install Unity.

  • Install dotnet and mono. These packages are for C# scripting on a mac and may be required. I like to use Homebrew for new installs. Homebrew is a cleaner way to add (and later remove) packages. With Homebrew installed run the following commands in your Terminal:

    brew install dotnet
    brew install mono

    If you want to learn more about a package before installing it run brew info [packagename] like brew info dotnet.

    You can also install dotnet and mono without Homebrew.

  • Install an IDE. You need an app to edit C# files. I recommend Visual Studio Code (VSCode). It's free and lightweight.

    • Install the C# helper. If you're using VSCode, install the C# extension by Microsoft. It will add suggestions and hints to your code.

  • Set your default script editor. In Unity go to Preferences > External Editor and select VSCode (or your editor of choice). This will open script files in the context of your Unity project.

  • Configure build settings. In the Unity Hub go to Installs, find the Unity version you're using, and click on the three dots (options menu) next to it. Select Add Modules and choose the platforms you want to build for.

You're ready to make a game!
