That way, you'll be able to easily switch back and forth between different Ruby and Rails versions. However, it's best not to mess around with the system-installed Ruby as it's intended to be used by the operating system and apps installed by Apple.So we'll use RVM to install a separate user-level Ruby environment, rather than mucking around with the system-installed Ruby.As I expected I ran into some trouble, though it wasn't as bad as I had feared.I had done a bit of research before I took the plunge so I knew pretty much what was going to break.Now you have the latest versions of Ruby and Rails installed!

Now that we have all the required software installed, let's create your first Rails app to make sure everything is working in harmony.

Never, ever, do a full version upgrade without at least one reliable backup of the disk you are installing to.

I use Time Machine for continuous backups, but to be extra safe I used Carbon Copy Cloner to make a bootable clone on a separate disk. With the backups checked and verified, I turned off Time Machine in the control panel and unplugged both of the external drives.

We'll create a simple application for managing a list of todos. Now you have everything you need to start building your own Rails apps.
