I have an app that is currently in the Mac App Store. It consists of the main app, and a bundle in the PlugIns folder (/Contents/PlugIns) as well as a Luncher helper /Contents/Library/LoginItems/

With Xcode 12.4 I am able to build but when I upload it to Apple I get a error:

ERROR ITMS-90296: "App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [( "com.xericdesign.earthdesk.mas.pkg/Payload/EarthDesk.app/Contents/Library/LoginItems/EarthDesk Launcher.app/Contents/MacOS/EarthDesk Launcher" )] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app."

The sandbox IS enabled for the Launcher.

This is very frustrating.
I responded on the other thread where you raised this.

Share and Enjoy
