I got a error when validate App as flow Asset validation failed 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.***.yyy.pkg/Payload/***.app/Contents/MacOS/zzz" )] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app. (ID: dc264017-f236-4e89-a100-e69c7f0fb318) zzz is a command tool build by make, I need codesign it. #1. use two lines below, run succes, but get 'App sandbox not enabled' problem codesign -s "TTT1" -f -v --timestamp --options runtime dist/m_arm64/zzz codesign -s "TTT1" -f -v --timestamp --options runtime dist/m_x64/zzz #2. use two lines below, reduce 'App sandbox not enabled' , but run zzz get 'zsh: trace trap' codesign -s "TTT2" -o runtime --entitlements zzz.entitlements -f dist/debug/zzz codesign -s "TTT2" -o runtime --entitlements zzz.entitlements -f dist/debug/zzz lipo -create dist/m_arm64/zzz dist/m_x64/zzz -output dist/zzz lipo -archs dist/zzz otool -L dist/zzz the zzz.entitlements content is the Info.plist embedded in zzz is #codesign both success codesign -d -vvv ./zzz #use method 2, the sandbox poblem ok codesign --display --entitlements - ./zzz why when codesign with entitlements, the zzz cant run success? if I upload to appstore, the client will get the zsh error? Has anyone encountered this kind of problem before? Reference: https://developer.apple.com/documentation/xcode/embedding-a-helper-tool-in-a-sandboxed-app
