After receiving the error message Unapproved Caller - SecurityAgent may only be invoked by Apple software, my Mac became unstable. It was unable to boot in safe mode. Eventually I erased the machine and did a total restore from time machine. Two days later I have received the same message again and my Mac crashed. All suggestions welcome.

Greetings shayw,
Thanks for visiting the Apple Support Communities! I understand that after receiving an alert on your Mac, which mentions an unapproved caller and that SecurityAgent may only be invoked by Apple software, your Mac becomes unstable. Further, you mentioned you were unable to start your Mac in safe mode.
To see if this is isolated to your macOS user account, I suggest testing the behavior with a different user account: How to test an issue in another user account on your Mac
Additionally, I suggest using First Aid with Disk Utility to help troubleshoot not being able to start in safe mode: Repair a disk using Disk Utility on Mac
Let me know how it goes from here.
Cheers.
