Prevent app re-adding itself to "open on login" list I have an app ("Android File Transfer"), that adds itself to the System Preferences → Users &amp; Groups → Login Items list. If I delete it with the "minus" button, the app re-adds itself next time it's launched. There is no option for controlling this in the app.

Is there any way to prevent an app from doing this?
Its kind of annoying but you can try locking the plist that controls login items.


Navigate to `~/Library/Preferences/loginwindow.plist
Select the file and press Command + I
Check "Locked"



Note: This will prevent all applications (and you) from adding or removing login items, so remove the application from login items and then lock the file.
