Discussion

In rare cases, an app might need to override or patch C code, use the long-deprecated NSCreateObjectFileImageFromMemory (which is fundamentally insecure), or use the DVDPlayback framework. Add the Allow Unsigned Executable Memory Entitlement to enable these use cases. Otherwise, the app might crash or behave in unexpected ways.

To add the entitlement to your app, first enable the Hardened Runtime capability in Xcode, and then under Runtime Exceptions, select Allow Unsigned Executable Memory.
