Hi All,
whoever is building the dmg files on binary, the 64-bit dmg file is fine and mounts OK. The 32-bit one isn't and refuses to mount on my 10.10.5 Yosemite Mac Mini. To reproduce, use the getGoodSpurVM.sh and getGoodSpur64VM.sh scripts in the image directory on MacOS. The former produces
"LSOpenURLsWithRole() failed with error -600 for the file /Users/eliot/oscogvm/image/squeak.cog.spur_macos32_x86_201808230550.dmg."
