Though the Mac isn't officially supported at CSU, there's probably and IDE that you can download for your Mac that looks very similar to the one we use in class.

Note: if you're not a Unix guru, don't sweat it. You can change directories by typing 'cd' and then the directory you want to go to. If you've set it up correctly (by creating the csci1301 folder), before you compile the first time, you can type cd /csci1301 and you will be in the right directory.
You may want to check out the Mac site for a program called Eclipse. It seems to be pretty powerful, and I think it's free.
