Mac OS 


mccPILOTLOG - Version 3.6 is developed for Windows PC only.  To run this Version on Mac OS, you need to install a virtual Windows System, like Bootcamp or Parrallels.

mccPILOTLOG - Version 4.0 is a crossplatform application developed for Windows PC and for Mac OS.  You do no longer need any virtual Windows anymore. 

In order to run, the application requires the following 3 components to be installed on Mac OS :

  • MONO Framework

  • XQuartz

  • mccPILOTLOG executable

These components are automatically installed with the installer package.  However, modifications to the OS environment, such as upgrading to Yosemite, may disrupt the installation, resulting in a failure to launch the application.

This solution focusses on the re-installation of the first 2 components.

MONO Framework

1) Open Finder and browse to the /Applications/Utilities folder

2) Double-click the Terminal icon to open a Terminal window

3) Type "mono --version" (without the quotes) at the command prompt and press the Enter/Return key

4) The output from Terminal should say "Mono JIT compiler version 3.2.x" along with some other miscellaneous information

5) If the above output was confirmed, continue with XQuartz...

If the Terminal output states otherwise, continue with the following steps to install the MONO version 3.2 :

1) Install the MONO Framework 3.2

2) Open Finder and browse to the location where you have saved the installer PKG file

3) Double-click on the downloaded MONO framework file and install the framework

4) After installation, you could run the earlier listed Terminal check again, just to make sure


1) Browse to the XQuartz landing web page

2) Install the latest version of XQuartz

Some pilots reported that they had to reboot the Mac in order to get all components and the application up-and-running.

Should the application still not launch after these fixes, contact the Helpdesk for further investigation.
