I have a Macbook with Mac OS X 10.7.5, so I am under the impression that it shipped with Ruby already installed. How do I find it and open it up to be begin working?
Thanks!

This should tell you the latest version of Ruby. (if installed)
You can do the same for Ruby on Rails = rails -v
Once you know what version of ruby you have, install rails and off you go :)
Enjoy

If you're not that comfortable with the command-line yet, check out JewelryBox app. Not only will it manage all your gems and rubies once RVM is installed, it can actually install RVM for you too!
