How can I use a .dmg file to distribute my Mac game build?

Using a .dmg File for Mac Game Distribution

Distributing a Mac game build effectively involves creating a .dmg (Disk Image) file, a common format for compressing and packaging software for macOS. Here’s a step-by-step guide:

Step into the world of gaming!

Step 1: Prepare Your Game Build

• Ensure your game is correctly compiled for macOS, utilizing tools like Unity’s build settings to export a Mac compatible version.
• Test your game thoroughly on macOS to confirm functionality.

Step 2: Create a .dmg file

1. Use hdiutil, a command-line utility, to create the .dmg file. This tool is native to macOS and provides flexibility in disk image creation.
2. Open Terminal and navigate to your game’s directory, then execute:

   hdiutil create -volname "YourGameName" -srcfolder "/path/to/your/game/" -ov -format UDZO YourGame.dmg

   This command creates a compressed, read-only .dmg image with the application’s files.

Step 3: Customizing Your .dmg file

• For a professional touch, use tools such as DMG Canvas or Disco to create a custom disk image background and layout.
• Place a shortcut to the Applications folder inside the .dmg to encourage users to drag and drop the app for installation.

Step 4: Distribute Your Game

• Host the .dmg file on your website, or utilize digital distribution platforms that support macOS games.
• Ensure that your hosting service is reliable and capable of handling the bandwidth needed for downloads.

Additional Considerations

• Sign your .dmg with an Apple Developer certificate to prevent gatekeeper issues during installation.
• Test the download and installation process before release to identify potential user issues.
