System Extension Redistributable Entitlement
A Boolean value that indicates whether other development teams may distribute a system extension you create.
Discussion
Add this entitlement to a system extension that you create and sign using your development team credentials, but which other development teams distribute in their apps. This extension allows a distributing app to have a different team ID than the one associated with the system extension. If this entitlement isn’t present, the team ID of the app and system extension must match.
