First of all a big thank you to ranch hand David Mason for pointing me to this site. The cattle drive will give me the challenges I need to learn, something a book on its own can't do. But before I can go for it I need to know if I can do this course with my Mac. I'm running MacOS 10.2.5 which has Java 1.4.1 as standard. I think this will let me do the Java and OOP assignments but I don't know about this Orion or MySQL stuff thats mentioned later on (If I ever get that far!). Will it work?
