Quite often iTunes Helper appears in the list of Login Items but in my Mojave version is no longer does. Thanks for checking and making that clear. Whilst you can Login to many of the Apple Servers with just an Apple ID the truth is that it is becoming increasingly more difficult to do so without it being and iCloud valid ID at the same time. Go to System Preferences > iCloud and double check that it is not logged in.įor FaceTime you will have to specifically open the app then go to the Preferences and untick the 'Enable this Account' box to stop it trying to Login in. This should stop Messages Launching a Start up. You may also need to sing out if it is using an Apple ID. Untick the 'Enable this Account' box if it is active. Specifically Open Messages and go to the Preferences (from the App Menu Bar item) and then the iMessages account. However if the Mac somehow thinks attempts where made to start the apps and that the Registration has not been completed then they will continue to Start up when the Mac does. If Messages and FaceTime are here you should remove them. (these are in addition to ones the system needs.)
Top right should be a button called 'Login Items' that reveals the items that will start up when the Mac does. That should be System Preferences then User and Groups then the Account you login to on the Mac.
