Compatibility :

Version 3.6 (Windows) and Version 4.0 (PC/Mac) are not compatible with each other.

mccPILOTLOG requires OS X  (Mavericks / Yosemite / El Capitan / Sierra / High Sierra).  The application does not run on Catalina or above !

Version 4.0 is a cross-platform application, hence the 3-step installation procedure :

1) Install MONO Version 3 Installer

2) Install Xquartz for Mac OS

3) Run the Installer Package for Mac

Important Note :

mccPILOTLOG – Version 4.0 is built on 32-bit technology.  It cannot run on macOS Catalina (or above) !

As from the release of Catalina, Apple decided to block all 32-bit apps. In case you upgrade your Mac to Catalina (or above), mccPILOTLOG will stop working! We cannot be held responsible for this, this is a decision by Apple.  Windows is also a 64-bit operating system, but continues to support 32-bit apps for a much longer time.

If your Mac is Catalina or above, you must switch to CrewLounge PILOTLOG. Our new logbook is a 64-bit application.

The mobile apps for mccPILOTLOG are companion tools to the main desktop application. The mobile apps cannot and should not be used as an autonomic pilot logbook.
