This is the download directory for McXtrace for Mac OSX. Please download the tarball appropriate for your version of OSX. You will need Xcode and XQuartz to run the installer. If you are unable to run either of these you might try to install the UNIX source packages instead (see http://downloads.mcxtrace.org/UNIX). If you need McXtrace for and older version of OSX please don't hesitate to contact the maintainer erkn_AT_fysik.dtu.dk, and we'll figure it out. Please also see http://www.mcxtrace.org/documentation/installation for detailed installation instructions
