macOS How to create an app that has no dock icon.

[jinksys]

I want to create an app that only runs in the status bar. I know how to create the icon and develop the app, but I don't know how to remove the dock icon and other menu items. I think this kind of program is called an agent?

Try adding the LSUIElement key to your Info.plist file with value 1. See Apple's documentation.
