Hello, We have a jenkins job, running on a linux machine, that is responsible for building and outputing a Pharo 4 development image + vm ready to be used on mac machines. We use this command line to download the VM and archived it as output of the job: curl -O http://files.pharo.org/vm/pharo/mac/Pharo-VM-mac-latest.zip On my mac (10.12.1), when i open the pharo image with this vm , I am facing what seem to be some known issues for Mac OS sierra: Pharo[13048:431565] *** -[NSPathStore2 stringByAppendingPathExtension:]: cannot append extension 'bundle/Contents/MacOS/' to path ... Now, when I try to download a Pharo 4 vm directly from my mac sierra machine, with a zeroconf script (get.pharo.org/vm40), It works: I am able to open the pharo image with this vm. Is there a script that allows to download a pharo 4 vm working for mac os sierra, from a linux machine ? -- Cyrille Delaunay
