SPSS 11.5 on Mac OS X 10.4
Installs perfectly.
Using tutorial files with Descriptive Statistics works fine, speed is very good. Will test with a real file from work soon.
Issue: shortcut keys work using alt-option key which is great, but if apple-command key accidently used, there's an issue with the GUI (screen doesn't refresh, some menus don't show up, things hovered over stay blue, etc). Restarting SPSS/Crossover solves it...
