Some more exploring

- downloaded cog_macos32x86_squeak.cog.v3_201608171728.tar.gz, started 
it and pointed it to a 4.2 image. Squeak stayed up, but the desktop 
never appeared.

- downloaded Squeak-4.6-All-in-One.zip and it runs, but warns it can't 
write the changes file (see attachment). Not sure how to deal with this 
or how to make this into a VM I can use for other images.

We have some image version checking in checkImageVersionFromstartingAt() that at least looks like it ought to be working out if the image format is correct and exiting cleanly if not, but I  don’t know what happens to plain ‘print()’ statements on macOS. Hmm, ok, try loading a 4.3 image in a spur vm - the console does actually show an exit from there with error 1, so it does work but boy is it failing to be helpful. How many people even know there is a console and to filter for ‘squeak’?
