Hi, David, Speaking of which, Treehouse just released a new workshop Installing a Ruby on Rails Development Environment in OS X 3 hours ago. You should definitely check it out.

Hi David, the installation instructions available on https://teamtreehouse.com/library/installing-a-ruby-development-environment/installing-a-ruby-development-environment/installing-ruby-on-mac should get you going. It's currently mentioned in the course notes for the Build a Simple Ruby on Rails Application.

It will assume however that you do have Git installed on your machine so you can download certain applications to get things going. On a Mac git does come installed by default.

Another resource that might be helpful, depending on your comfort level with terminal would be https://gorails.com/setup/osx/10.10-yosemite but I think the first link should get you through it without any issue.

On a Mac git does come installed by default.

I'm not sure here. Does git come preinstalled on a Mac by default or is it distributed as part of the Xcode command line tools?

I've used git on a fresh installation of mac before prior to Xcode. I believe however that Mac will update your version with Xcode command line tools. Mac does however come with a lot of development tools built in like git, Ruby, Rails, and Python... most however aren't the most current version.

That being said I think it's always a good idea to grab the Xcode command line tools. For those users not familiar with creating an Apple Developer account you can just grab Xcode from the App Store to install it. There is a great link at https://railsapps.github.io/xcode-command-line-tools.html that can help those unfamiliar with that process.

thanks Tim for the clarification. This question has been bothering me for quite some time.

For a long time, I assumed that those tools were preinstalled on a Mac as default.

But you see, some students mentioned during forum posts that on their fresh-installed Yosemite, when entering commands such as git, ruby in the Terminal, they got the command not found message.

And I just have no idea why, Xcode and its command line tools are the first things I install on a new OS X; and it's not like I can just reinstall my Mac only to test whether their saying is true.
