Before you submit your macOS app to the Mac App Store, test the installation process to verify that your app installs correctly. Do this by exporting your macOS app and selecting the “Save for Mac App Store Deployment” option. Then run this test using the installer command before you upload your app to iTunes Connect. The installer command verifies that your app will be installed correctly when it’s purchased from the Mac App Store.
In a Terminal window, execute the following command:
sudo installer -store -pkg path-to-package -target /The output of the installer command should be similar to:
rpatel$ sudo installer -store -pkg ../Documents/TrackMix.pkg -target /WARNING: Improper use of the sudo command could lead to data lossor the deletion of important system files. Please double-check yourtyping when using sudo. Type "man sudo" for more information.To proceed, enter your password, or type Ctrl-C to abort.Password:installer: Note: running installer as an admin user (instead of root) gives better Mac App Store fidelityinstaller: TrackMix.pkg has valid signature for submission: 3rd Party Mac Developer Installer: Ravi Patel (7U3X8B3P5Z)installer: Installation Check: Passedinstaller: Volume Check: Passedinstaller: Bundle com.example.rpatel.TrackMix will be installed to /Applications/TrackMix.appinstaller: Starting installinstaller: Install 0.0% completeinstaller: Install 90.8% completeinstaller: Install 100.0% completeinstaller: Finished installrpatel$ If the installer finds a bundle with the same bundle ID as the one it’s installing, it upgrades the existing app. Users can then install upgrades even if they have moved your app. If you have a copy of your app installed (for example, in your build products directory), you may want to remove it so that the installer installs your app in /Applications. Other options include archiving the existing version in a ZIP file or moving it to another volume and unmounting that volume.
