Greetings Keepers of the Scheme,
First timer on MacOS...
I downloaded 9.2 to a 10.9.2 MacOS machine, installed and checksum'd without issue.
Double clicking on the icon resulted in nothing happening.
Via the terminal, after digging into the package, the 'start' binary gave a display of edwin but interaction caused a crash. After a few minutes the process started spinning and gobbled up all CPU.
I downloaded 9.1 and installed it without issue. It did however prompt me to install X11.
