When trying to open an encrypted CoreML model file on a system with SIP disabled, the error message is
Failed to generate key request for <...> with error: -42187
This should state that SIP is disabled and needs to be enabled.
That seems like a reasonable request. The best way to get it to the folks who have the power to enact change is to file it officially using Feedback Assistant.
Please post your bug number, just for the record.
Share and Enjoy
