macOS Code Signing Guide

To sign a macOS installer (.dmg), you need:

• A Mac
• A subscription to the Apple Developer Program, which costs $99 per year

Once you have these, watch this detailed video to learn how to sign apps for macOS:

The video covers:

• Enrolling in the Apple Developer Program
• Creating a certificate
• Configuring your app for code signing
• Building and signing your app
• Using GitHub Actions and S3 for upload

Note

While the video demonstrates general Electron macOS signing, you will need to adjust the steps specifically for Botasaurus Desktop, which is easy. A dedicated tutorial is coming soon.

Tip

If you are a nonprofit organization or educational institution, you may qualify for Apple's Developer Program fee waiver. The waiver removes the $99 annual charge, saving you about $1,000 over a decade.
