I have developed a backup application in Java. In it, users can configure whether they want it to autostart or not. If they do, a plist file is being written to ~/Library/LaunchAgents so that my app starts at login. This works perfectly so far.
I've not submitted it to the Mac App Store. But for that, it needed to be sandboxed. And with that, I had to add a "com.apple.security.temporary-exception.files.home-relative-path.read-write=/Library/LaunchAgents/" to my entitlements so that the plist file could still be written to ~/Library/LaunchAgents. However, they do not approve this.
Is there another solution to launch my application at login?
Must work with sandbox-mode
Must work from Java/Shell/... (I found "SMAppService", but this seems only available in Swift/Objective-C)
