Reinstall apps that came with your Mac
If you delete an app, you can reinstall it.
To reinstall an app that came with macOS (for example, iTunes, Photos, Calendar, Safari, and more), reinstall macOS.
Reinstalling macOS doesn’t erase your information.
To reinstall an app from the App Store, see the App Store User Guide.
If the apps came on a disc, and don’t appear in the App Store, use the disc to reinstall them.
Thanks for your feedback.
