Hi Dario

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. 
I've got some older Pharo 1.2.2 images and either 

Cheers
Carlo

Ciao,

i have a old

Pharo1.4
Latest update: #14445

run on MacBook with Mac OS X 10.7.5 ( Lion ).

In this system the Pharo image run fine.


I copy the relative folder on a MacBook  with Mac OS X 10.14.6 ( Mojave ).

Now in this system,

when i double click on the relative folder icon  the system open a empty black foreground window.

The System Application don't  report any Pharo application.

I need to register - install a Pharo application?


In this last system i also copy  a Pharo GemTools-1.0-beta.8.7-3101 folder.

It run without problem.

Any consideration is welcome.

Thanks,

Dario
