macOS 10.12.2 appears to have brought with it some GPU issues

I run Einstein@Home, using both CPU cores & my GPU.  Other than a few month period where Einstein@Home was issuing broken GPU work units, I’ve been successfully doing this for years, I think.  Longer than I can really remember, in any case.
