Use Software Update
- Choose System Preferences from the Apple menu , then click Software Update to check for updates.
- If any updates are available, click the Update Now button to install them. Or click “More info” to see details about each update and select specific updates to install. You may be asked to enter your administrator password.
- When Software Update informs you that your Mac is up to date, the installed version of macOS and all of its apps are also up to date. That includes Safari, Music, Photos, Books, Messages, Mail, Calendar and FaceTime.
- To install future updates automatically, including for apps that you've downloaded from the App Store, select “Automatically keep my Mac up to date”. Your Mac will notify you when updates require it to restart, so you can always choose to install those updates later.
