To check for Mac software updates, open the App Store app on your Mac. Click Updates in the App Store toolbar, then use the Update buttons to download and install any updates listed. Updates installed in the last 30 days appear below this list.
If you don't see an expected update for Mac:
- Install any updates that are listed, then return to the Updates tab to check again. If you still don't see an expected update, use the Search field to find the app that you want to update.
- Updates for Safari and Mac firmware might not appear, because you get them as part of macOS updates.
- If you didn't get an app from the App Store, check with the maker of the app for updates.
- If you're using OS X Snow Leopard or Lion, get OS X updates by choosing Software Update from the Apple () menu.
Learn how to upgrade to the latest macOS, which includes the latest Safari and App Store.
- Get updates for iPhone, iPad, or iPod touch.
- Redownload apps that you previously downloaded.
- You can set your App Store preferences to ”Download newly available updates in the background.” If you're using OS X El Capitan v10.11.5 or later, these updates include major new macOS versions, such as macOS High Sierra. Your Mac then notifies you when the updates are ready to install.
Large automatic updates don't occur when your Mac is using a Personal Hotspot, and if your business or school network doesn't allow secure connection to Apple's software-update servers, you might need to download updates manually.
