Most of the Apple apps that come with a new Mac were installed as part of the Mac operating system (macOS). These include apps such as Safari, iTunes, Books, Messages, Mail, Calendar, Photos, and FaceTime. To update them, just follow the steps to update the software on your Mac.
To update preinstalled apps that aren't part of macOS, you might first need to accept those apps in the App Store:
- Open the App Store app on your Mac.
- If you're using macOS Mojave, click the sign-in button or your photo in the lower-left corner of the window. If you're using an earlier version of macOS, click the Purchases tab at the top of the window. You might be asked to sign in with your Apple ID.
- If you have any unaccepted apps, the App Store should now show an Accept button, followed by a list of those apps. Click the Accept button. You might be asked to sign in again with your Apple ID.
You can now use the Updates tab of the App Store to check for updates to each app you accepted, as well as any apps you downloaded from the App Store. You can also redownload your apps, if necessary.
