Can't launch Mini vMac on Catalina

Post by GeorgeJ »

When I try to launch Mini vMac on my new iMac running Catalina (10.15.7), I get an error message ("The application 'Mini vMac' can’t be opened.") If I right-click or control-click on Mini vMac and select "Open" (such as to enable launching an application that is not registered with Apple), I get the same error message.

However, I can successfully launch Mini vMac on my MacBook Pro running High Sierra (10.13.6).

'Any ideas?

Thanks,
George

P.S. My ultimate goal is to get a copy of SonyTest 7.0 onto my Macintosh SE to help me diagnose a floppy drive problem. I think the floppy drive heads need alignment, but the drive might have another problem. (It is not as simple as the eject motor needing cleaning, lubrication or a replacement gear. All that has been done.) I do not have an alignment floppy, but I do have fairly serious electronic diagnostic equipment (o'scope, etc.) Any hints on diagnosing problems with 800K floppy drives, schematics, etc. would be welcome, too.

Mini vMac runs fine here on Catalina.
Could it be that you you have an old 32-bit only version of Mini vMac? Try a newer Mini vMac build.
