Hi Esteban,

    you'll find that my Mac VMs as of r2519 do "the right thing", agreeing with the linux VM.  See

Hi,

I was trying to fix this, but seems to be a problem (besides the "'-psn_0_528513'", which is an error).
According SmalltalkImage>>#getSystemAttribute: comment, getSystemAttribute: 0 shouldn't answer the executable name, but the VM path:

     0               the full path name for currently executing VM
                      (or, on some platforms, just the path name of the VM's directory)

...so... getSystemAttribute: 0 is answering fine... and -1 should answer nil (or the vm parameters, if present), not the executable name. Real problem then is:

we don't have a way  to get the executable name

or

getSystemAttribute: comment is wrong :)

what's the audience opinion?

cheers,
Esteban
