How to check for app and macOS updates in the Mac App Store

The Mac App Store is more than just a convenient way to download apps. It's also the only way to download the latest system software updates. Not just major operating system updates like macOS Sierra either, but also important security updates, incremental changes to support software, and all the apps you use every day.

Note: Before you apply any operating system updates, it's a very good idea to back up your Mac. Apple makes updating as safe and easy as possible, but accidents and problems can still happen. Backing up will give you a safe point to restore from if anything goes wrong. To find out more about backing up your Mac, check out this helpful guide:

How to check for app and macOS updates in the Mac App Store

  1. Open the Mac App Store from your Dock or the Finder.
  2. Click on the Updates tab. (You may be required to enter your Apple ID and password before you can check.) The Updates menu populates with a history of all the apps and system software you've already updated in the last month. Any new updates will appear at the top.

  3. Click the Update button to being the download, or if there are numerous downloads, click the Update All button.

Some system software updates will require you to restart your Mac before they can be applied. That's perfectly normal if the changes the updates make will affect core technologies. Just make sure you've saved all your work, or schedule the restart for when it's more convenient.
