I had a similar situation due to a deprecation warning generated by my startup script. I aborted from the debugger, and the image worked normally, but when I saved, quit and tried to restart the image, it wouldn't open (VM icon in list of active apps, but window never appeared macOS high Sierra). ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
