How to upload app to macOS

1. Open Terminal

• Press Cmd (⌘) + Space, type Terminal, and hit Enter.

2. Navigate to Your Build Output Directory

Your .app file is likely located in the publish folder within your project directory. Run:

 cd /path/to/your/project/bin/Release/net8.0-macos/publish

Replace /path/to/your/project with the actual location of your project.

3. Run the productbuild Command

Now, create a .pkg file:

productbuild --component YourApp.app /Applications YourApp.pkg

Replace YourApp.app with your actual .app file name.

4. Verify the Output

After running the command, you should see YourApp.pkg in the same directory.
