Mac Patro (Now Open Source!)

I’m excited to announce that Mac Patro, the simple and lightweight menu bar app for the Nepali calendar, has been completely rewritten in Swift and is now fully open source!

This new native version offers significant improvements over the original Electron app, including:

  • Better Performance: It’s faster and uses fewer system resources.
  • Smaller Size: The application is much more lightweight.
  • Universal Binary: A single download works on both Intel and Apple Silicon Macs.

A Fun Disclaimer: This app was rewritten in Swift (a language I don’t know) with about 80% of the code generated by AI. I was constantly in the loop, guiding and reviewing, but as a non-Swift developer, I welcome any and all feedback on the source code! It’s a testament to how AI can help us build what we love.


Downloads and Source Code

Important: Before you download, please read the installation instructions to ensure the app runs correctly on macOS.


Installation and Troubleshooting

  1. Download the Mac.Patro.vX.X.X.dmg file from the GitHub Releases page.
  2. Open the .dmg file.
  3. Drag the Mac Patro.app icon into your Applications folder.

A Quick Heads-Up for macOS Users

Because the application is not yet notarized by Apple, you might see an error message like this the first time you open it:

macOS security error message

This is a standard macOS security measure.

To fix it, just open the Terminal app and run this command:

xattr -cr /Applications/Mac\ Patro.app

After running the command, the app will open without any issues.
