On your Mac, do any of the following:
- For apps downloaded from the Internet: In the Downloads folder, double-click the disk image or package file (looks like an open box). If the provided installer doesn’t open automatically, open it, then follow the onscreen instructions.
Note: If you get a warning dialogue about installing an app from an unidentified developer, see Open a Mac app from an unidentified developer.
- For apps on a disc: Insert the disc into the optical drive on your Mac or connected to your Mac.
To reinstall apps you downloaded from the App Store, use App Store. See Install purchases from the App Store on Mac.
You can remove apps that you downloaded and installed from the Internet or from a disc.
- On your Mac, click the Finder icon in the Dock, then click Applications in the Finder sidebar.
- Do one of the following:
- If an app is in a folder, open the app’s folder to check for an Uninstaller. If you see Uninstall [App] or [App] Uninstaller, double-click it, then follow the onscreen instructions.
- If an app isn’t in a folder or doesn’t have an Uninstaller, drag the app from the Applications folder to the Trash (at the end of the Dock).
WARNING: The app is permanently removed from your Mac the next time you or the Finder empties the Trash. If you have files that you created with the app, you may not be able to open them again. If you decide you want to keep the app, get it back before emptying the Trash — select the app in the Trash, then choose File > Put Back.
To uninstall apps you downloaded from the App Store, use Launchpad.
