Very strange Mac OS crash in one of my apps

Targets macOS

We’re only seeing this at one location, and I’ve never seen anything like this ever in my life of developing for the Mac platform.

May 4 08:35:37 amcintyre-pc BRU PE[79842]: The application quits now due to an unhandled NSInternalInconsistencyException.

The curiosities are the NSInternalInconsistencyException and the unsupported compressor errors.

Any ideas in Mac Land?

Are you using any declares or plugins?

I saw crashes like this with early releases of 10.13, I haven’t seen one for a while. They seemed to clear up when either a customer does a clean install or updates to the next release of HS.

I’ll have to see what the full version of Mac OS this is. The user just reported 10.13 and the crash segment he sent us was incomplete.

The unsupported compressor sounded familiar: https://forum.xojo.com/42076-high-sierra-applefscompression-unsupported-compressor/0

Thanks, Trixie, that does seem to be consistent with what is being reported. I’ve sent the user a message asking WHICH version of 10.13 they are using. Since this is only one user of literally 1,000’s of users, I’m not to concerned about it being BRU PE or Xojo.

It turns out that the user had locked that machine on a developer pre-release version of 10.13.0 because it was the last version of 10.13 that would still run his Final Cut Pro 7.

He’s installing a second drive so that he can run 10.13.4 normally, and then reboot into the pre-release when he has to open an old FPC 7 project.
