I'm having a pretty bizarre problem in OSX Mavericks. I'm attempting to install a fresh version of the OS, so I boot to OSX Utilities (Cmd+R). The option that I'm looking for is listed (re-install operating system), but I can't select it or anything else from the list.
I can move the mouse around, but clicking does not work. I tried with both the trackpad as well as a USB mouse. I can navigate through the options with the arrow keys, but pressing enter has no effect.
How the heck am I supposed to do anything from the utilities?
