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):

http://files.pharo.org/vm/pharo/mac/

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:

https://bintray.com/opensmalltalk/vm/cog/201703051406#files

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.

Best,
