Ciao Carlo,

thanks.


As far as I know there was an issue with the older VM's on Mac OS X where the graphics subsystem changed, causing that blank/black screen.

You will probably be able to use a different VM and make it work. 

Excuse my ignorance but I have no experience in this regard.

I've got some older Pharo 1.2.2 images and either 
  • CogMT.3390.app (Squeak Cog 4.0.3390)
  • or maybe even one of the other mac vm's from around that time will work.


Where i can download a valid mac vm's ?

And where should i put it ?

The Pharo on my system have a Contents folder,

which inside has:  info.plist
MacOS folder
with: Pharo ( exec )
 Plugins folder 
Resources  folder

Do you need more information?

Thanks,

Dario
