 Maybe a better thing to do is to DYLD_PRELOAD `imagent` and swizzle `IMDAuditTokenTaskHasEntitlement` to always return YES. 
 
+Included in the project is "kordophoned-RestrictedEntitlements.plist", which contains all necessary restricted entitlements. 
+On production macOS builds, the kernel will kill kordophoned immediately if it's signed using restricted entitlements, so agent hook is a
+better option when running on prod machines. By default, the project is configured to ignore kordophoned-RestrictedEntitlements.plist when building. 
 
 ## Building/linking 
 If you get dyld errors running from the command line, use `install_name_tool` to update the @rpath (where @rpath points to where linked Frameworks like GCDWebServer is).
