I've setup Hercules on my Mac before. Fun tool, since I last touched OS2/MVS 40 years ago. Best part is many of the old OS's (MVT, MVS, vm/370) are all still available since IBM never saw the need to copyright them.
The ARM Mac version crashes instantly upon launch with a window reporting a broken pipe error, and attempts to 'report and send diagnostics' gets the same problem.
Well, I tried to try it. I guess I'll just bookmark it and try again at a later date.
