Spotlight helps you search and find anything on your Mac. It indexes the contents of your Mac's hard drive to make it easier to find documents, emails, apps, music, contacts, and other information.
Click on the Spotlight button in the menu bar on the top right. It looks like a magnifying glass. Or, use the Command + Space keyboard shortcut.Â
The Spotlight search field will appear in the middle of your screen. Type in your search query. Spotlight will return results as you type.
