Same issue here. Invalid code signing entitlements. Your application bundle’s signature contains code signing entitlements that aren’t supported on macOS. Specifically, the “[TeamID.mydomain, group.mydomain]” value for the com.apple.security.application-groups key in “mydomain.pkg/Payload/MyApp.app/Contents/MacOS/MyApp” isn’t supported. This value should be a string or an array of strings, where each string is the “group” value or your Team ID, followed by a dot (“.”), followed by the group name. If you're using the “group” prefix, verify that the provisioning profile used to sign the app contains the com.apple.security.application-groups entitlement and its associated value(s). My macOS App contains two group "group.mydomain" and "TeamID.mydomain". Last release version, Xcode uploading works, but today Xcode send me the "Validation failed" error. Even I Validate my last release version in Xcode Organizer, it returns the same error. I have try the manual provisioning profile, it does not works. Maybe it's a server-side validation issue.
