Hi,
You need a VM with the SqueakV3 memory manager and compiled in the past few months for Mac OS X Sierra support.
All recent Pharo VM are compiled with the Spur memory manager leading to this error ���This interpreter (vers. X) cannot read image file (vers. 6505)���.
I would try the latest VM from this repository (latest.zip):
If you get the second error ( [NSPathStore2 stringByAppendingPathExtension:]: cannot append extension 'bundle/Contents/MacOS/' to ��� ), it means the VM is too old and does not support Mac OS X Sierra.
In this case, try instead the VM named:
cog_macos32x86_squeak.cog.v3_201703051406.tar.gz
present at:
It should work but it is not a Pharo VM hence some features may be disabled (specific VM plugins, etc.). Depending on your use-case it may be enough or not.
