Start Applications Automatically after Login on Your MacBook
Here’s one advantage to logins: Each account can have its own selection of applications that run automatically when that user logs in. These applications are Login Items, and they appear as a list in the Users & Groups pane.
A caveat or two:
The user setting his or her Login Items must be logged in. Only the user can modify his or her own Login Items.
Users must have access to System Preferences, or must be able to launch the application. If the person is using a standard-level account and wants to access the account’s login items, the account must allow access to System Preferences; alternatively, the user can launch the application and then right-click the application icon in the Dock and choose Options→Open at Login from the contextual menu.
Including an application in your Login Items list is easy: Click the button with the plus sign to navigate to the desired application, select it, and then click Add. (Alternatively, you can just drag items from a Finder window and drop them directly into the list.)
Note that items in the list are launched in order, so if something needs to run before something else, you can drag the item entries into any sequence.
To launch the application in hidden mode — which may or may not display it in the Dock, depending on the application itself — click the list entry for the desired item and select its Hide check box.
