Login items installed using the Service Management framework are not visible in System Preferences and can only be removed by the application that installed them.

Login items installed using a shared file list are visible in System Preferences; users have direct control over them. If you use this API, your login item can be disabled by the user, so any other application that communicates with it it should have reasonable fallback behavior in case the login item is disabled.

The important thing is that, annoyingly, you have to copy your built, main app to the Applications folder and don't do what I do which is forget to sandbox the helper-app and add a Application is agent (UIElement) row to the helper's plist with TRUE for the value.

Adding Login Items. There are two ways to add a login item: using the Service Management framework, and using a shared file list. Login items installed using the Service Management framework are not visible in System Preferences and can only be removed by the application that installed them.

Adding Login Items Using the Service Management Framework

Applications can contain a helper application as a full application bundle, stored inside the main application bundle in the Contents/Library/LoginItems directory. Set either the LSUIElement or LSBackgroundOnly key in the Info.plist file of the helper application’s bundle.

Use the SMLoginItemSetEnabled function (available in OS X v10.6.6 and later) to enable a helper application. It takes two arguments, a CFStringRef containing the bundle identifier of the helper application, and a Boolean specifying the desired state. Pass true to start the helper application immediately and indicate that it should be started every time the user logs in. Pass false to terminate the helper application and indicate that it should no longer be launched when the user logs in. This function returns true if the requested change has taken effect; otherwise, it returns false. This function can be used to manage any number of helper applications.

If multiple applications (for example, several applications from the same company) contain a helper application with the same bundle identifier, only the one with the greatest bundle version number is launched. Any of the applications that contain a copy of the helper application can enable and disable it.

Adding Login Items Using a Shared File List

This method is available in OS X v10.5 and later. For specific details, see the appropriate functions in Launch Services Reference.

Deprecated APIs

In previous versions of OS X, it is possible to add login items by sending an Apple event, by using the CFPreferences API, and by manually editing a property list file. These approaches are deprecated.

If you need to maintain compatibility with versions of OS X prior to v10.5, the preferred approach is to use Apple events; for details, see LoginItemsAE. Using the CFPreferences API is an acceptable alternative. You should not directly edit the property list file on any version of OS X.

Your home folder contains many files and folders that apps on your Mac have permission to read or modify. If you use Get Info or other methods to change those permissions, you could experience issues such as these:

Changes that you make in System Preferences aren't saved after you quit System Preferences.
Changes that you make to the Dock aren't saved after you log out of your user account.
Windows that were open the last time you logged out or quit an app (before you changed permissions) open again after you log in or open the app.
You're asked for an administrator name and password when moving certain items in the home folder.
You repeatedly get a message that macOS needs to repair your Library to run applications.
When saving changes to an item, you get a message that the file is locked or you don't have permission to save.
Preview, TextEdit, or other sandboxed apps unexpectedly quit when opened.
You get an alert that the startup disk has no more space available for application memory.
Activity Monitor shows that Safari or SafariDAVClient is using a large amount of system resources.
Your Mac performs slowly.
iTunes says that your device cannot be synced.
Photos and videos that you import into Photos or iPhoto don't appear within the app, but do appear in Finder. Or your library needs to be updated or reselected each time you open Photos or iPhoto.
