Thanks again for all your help. Although it is beyond my understanding, user WestFacingBucket on reddit posted this in response to a thread regarding choosing cards based on OpenGL. I'm not sure if it is news or has any meaningful use to you--particularly being as vague as it is--but I thought I'd pass it along anyway.

Ah, well, thanks for the help. Things like this continue to push me away from the brand. I'll avoid the disable and look into cost-free dual boot options. Does my license for PZ work across different OS?

I think you're missing a link. What are the errors so that I can report them to Apple?

It appears to have both the 4000 built in and the 650M on a PCIe. But "about..." only reports the 4000 In the summary.

I'm certain. The Intel HD Graphics 4000 was the integrated option for the unibody in 2012. TheLonestander has the same card without the same issue.

Exact same problem. Mojave 10.14.6 MBP 15 inch mid 2012 2.3 GHz Intel Core i7 4 GB 1600 MHz DDR RAM Intel HD Graphics 4000 1536 MB I also upgraded to a 500 GB SSD when this hard disk began to fail last year. Some discussion regarding Open GL and case sensitive file systems on this reddit thread.
