Additional information

I tried reproducing the issue using a clean Electron app but with no luck:

1. Initialize the app

npm init electron-app@latest my-app
cd my-app

2. Edit forge.config.js and add DMG maker:

    {
      name: '@electron-forge/maker-dmg',
      config: {
		  icon: 'assets/studio-app-icon.icns',
	  },
    }

3. Run the build:

FILE_ARCHITECTURE=x64 node_modules/.bin/electron-forge make --arch=x64 --platform=darwin

There were bugs with node-gyp and having a system Python version that didn't include setuptools. The newest version of Forge (containing @electron/rebuild@^3.7.0) should fix this issue.
