Startup items are applications, documents, shared volumes, or other items that you want to open automatically when you log in to your Mac. For example, you might want Apple Mail, Safari, or Messages to always open when you use your computer. Instead of manually launching these items, designate them as startup items and let your Mac do the work for you.

You have a wide range of options when adding startup items through your Mac's System Preferences. Here's how:

Log in to your Mac with your account information.

Select System Preferences from the Apple menu. You can also click the System Preferences icon in the Dock.
