I am referring to the Message+ application for macOS. I use the Message+ app, available from the Apple App Store, on my iMac desktop computer. 'Login Items' is a feature of user accounts in the macOS operating system. In the macOS System Preferences, under the category Users & Groups, there is a 'Login Items' tab, which permits the owner or administrator of that user account to add or remove applications or other processes to a list a items that will start up automatically whenever the machine is started up. If Message+ is not in that list, it does not automatically run when the iMac and started, and it will remain in that state as long as I don't manually run Message+. The second I run Message+ to check messages on my iMac, it adds itself to the Login Items list, without asking me for permission to do that, and without giving me the option to opt out of that default behavior. After running the app, the next time I shut down and restart the iMac, the Message+ app automatically runs and pops up on my screen. I have to go into my Login Items list to manually remove it from there, so that it doesn't start up automatically again. I want a way to PREVENT the app from adding itself to my Login Items.
