[Pharo-dev] Using a newer vm with PharoLauncher, platform differences

I wanted to use a newer vm with PharoLauncher, so I added a vms directory in /Users/stephan/Library/Application Support/Pharo/ and used curl get.pharo.org/vmLatest50 | bash to install it there. In PharoLauncher I then set the vm full path to either /Users/stephan/Library/Application Support/Pharo/vms/pharo-vm/Pharo.app/Contents/MacOS/pharo or /Users/stephan/Library/Application Support/Pharo/vms/pharo-vm/Pharo.app Neither works to launch an image (Mac 10.10.5). The similar procedure on Ubuntu 15.04 works (though the apt dependencies of SDL2/Cairo/Freetype:i386 are somewhat broken). What is the vm path supposed to be? Stephan
