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.
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.
