The open source track planning software XTrackCAD is a fantastic tool in anyone playing with model railways but without a stable release in 5 years it’s lagged a little behind Apple’s operating system updates. Installing on OS X 10.10 does not work out of the box but if you follow these steps you’ll have a running application in no time.

  1. Download and install the latest XQuartz

    You can get it from

  2. Download and install XTrackCAD as with earlier OS X installations

    The files are hosted on the project sourceforge page.

  3. Make sure you have allowed access to applications from any developers

    There are various instructions but try this walk through.

  4. Replace some out of date libraries in the XTrackCAD bundle

    Open a terminal and execute the following commands:

    cd /usr/lib
    cp libxml2.2.dylib  /Applications/
    cp libiconv.2.dylib  /Applications/
    cp libz.1.dylib  /Applications/

There you go – everything should be working correctly after this. Thanks for the hints from tynewydd962 in the XTrackCAD forum.
