Thanks goodness that the version# is part of the dmg file’s name. So please go ahead to and download XQuartz-2.7.4.dmg. You should use XQuartz version 2.7.2 or later. Which in turn led me to XQuartz project: Link. Tried to install the version for OSX ( evtx_view.v.0.69.), but the system barked at me, that I needed X11 server and client libraries for OS X Mountain Lion. So what to do, tried using the App Store. I need to send Windows Event Viewer Log files (*.evtx) to a colleague whose primary work computer is a Mac OSX. As always, it is one inter-operability problem or another.
