Latest Version Of Mac Software

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

How to get updates for macOS Mojave or later

If you've upgraded to macOS Mojave or later, follow these steps to keep it up to date:

1. Choose System Preferences from the Apple menu , then click Software Update to check for updates.
   
2. 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.
   
3. When Software Update says 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, iTunes, Books, Messages, Mail, Calendar, Photos, and FaceTime.

To find updates for iMovie, Garageband, Pages, Numbers, Keynote, and other apps that were downloaded separately from the App Store, open the App Store on your Mac, then click the Updates tab.

To automatically install macOS updates in the future, including apps that were downloaded separately 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 later.

How to get updates for earlier macOS versions

If you're using an earlier macOS, such as macOS High Sierra, Sierra, El Capitan, or earlier,* follow these steps to keep it up to date:

1. Open the App Store app on your Mac.
2. Click Updates in the App Store toolbar.
3. Use the Update buttons to download and install any updates listed.
4. When the App Store shows no more updates, the installed version of macOS and all of its apps are up to date. That includes Safari, iTunes, iBooks, Messages, Mail, Calendar, Photos, and FaceTime. Later versions may be available by upgrading your macOS.

To automatically download updates in the future, choose Apple menu  > System Preferences, click App Store, then select ”Download newly available updates in the background.” Your Mac will notify you when updates are ready to install.
