I have the same trouble. Sometimes I get SMAppServiceStatusNotFound status. I noticed that my macOS app is not in the System Preferences/Login Items/Allow Background apps list. So I did run a terminal command sudo sfltool resetbtm I rebooted, and my app was in that list. I had to turn back off all the apps in the Allow Background list, which turned on since the Terminal command. You would agree with me, this is not the way to distribute the app to the customers. I can't ask my customers to run the Terminal command, reboot then turn off all the unwanted apps from the "Allow Background" list. I guess I miss something. Any idea? How to get my app in that list just after I copied the app within the /Applications folder?
