Uninstall MacRuby
macos, macruby, ruby, uninstallation
Solution
I believe everything for MacRuby is installed into /Library/Frameworks/MacRuby.framework. While I haven't tried it myself, removing that directory should remove MacRuby from the system.
MacRuby shouldn't interact with RubyCocoa in such a way as to cause it to stop working. It maybe the case that something else on your system changed at about the same time as the MacRuby install.
Problem
Does anyone know how to uninstall MacRuby? I was using RubyCocoa then decided to try out MacRuby, after installing MacRuby, RubyCocoa has stopped working. So I would like to remove MacRuby, but I cannot find any documentation on how to uninstall it.
