Xamarin Mac Enable sandboxing

Question

I have used FFMPEG for Xamarin Mac project to compress the video.

But I am facing the issue as below.

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.amit.CVLive.pkg/Payload/CvLive.app/Contents/MacOS/CvLive", "com.amit.CVLive.pkg/Payload/CvLive.app/Contents/Resources/FFMPE3/ffmpeg", "com.amit.CVLive.pkg/Payload/CvLive.app/Contents/Resources/ffmpeg" )] Refer to App Sandbox page at https://developer.apple.com/devcenter/mac/app-sandbox/ for more information on sandboxing your app."

Answer 1

I was having the same issue, On the "Mac Signing" option make sure:

• Choose a custom etitlements file
• Enable the option "Sign the installer packer"

before archiving the App for publishing
