How to Update macOS on Your Mac

To maintain your computer’s security, stability, and compatibility, Apple recommends using the latest macOS that is compatible with your Mac. macOS updates and upgrades also include the latest features and built-in apps such as Safari, Mail, and Apple Music.

Using the built-in Software Update feature is the easiest way to keep your Mac up to date. Software Update finds, downloads, and installs Apple software updates and upgrades that are compatible with your Mac model.

Before installing new software, it’s a good idea to back up your Mac. Once done, simply follow the steps below.

1. Open Software Update:
   • Use Spotlight in the menu bar to search for “Software Update,” then click to open it from the search results.
   • Or choose System Settings from the Apple menu  in the corner of your screen. In the window that opens, click General in the sidebar, then click Software Update on the right.
   • If your older Mac doesn’t have Software Update, use other ways to download and install macOS.
2. When Software Update opens, it automatically checks for new software. If new software is available for your Mac, click the Update, Upgrade, or Restart Now button to install it.
3. If no new software is available for your Mac, Software Update says that your Mac is up to date. To check again, click Check for Update, press Command-R on your keyboard, or close and reopen Software Update.
4. Before installation begins, you’re asked to enter your administrator password. It’s the password you use to log in to your Mac. Forgot your password
5. Allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar or blank screen several times.
