Customize DMG Window

Tauri exposes bundle configuration options allowing us to customize this

{
  "bundle": {
    "active": true,
    "targets": ["dmg"],
    "macOS": {
      "dmg": {
        "background": "./src-tauri/dmg-background.png",
        "windowSize": {
          "width": 700,
          "height": 460
        },
        "appPosition": {
          "x": 180,
          "y": 220
        },
        "applicationFolderPosition": {
          "x": 500,
          "y": 220
        }
      }
    }
  }
}
