Here you will find a collection of migration guides and videos as well as links to the AutoLISP and ObjectARX developer documentation that will be essential for developing AutoCAD 2012 for Mac applications.
AutoCAD 2012 for Mac is a native 64-bit Mac OS X application developed in C/C++ and Objective-C. It is built on top of a cross-platform CAD engine that was factored out of the AutoCAD codebase and is now shared between the Windows and Mac OS X versions of AutoCAD. The core CAD engine supports a cross-platform abstract host interface that is implemented in terms of platform-specific code. This design allows the application itself to support a native Mac OS X interface while using the same CAD engine that drives the Windows version - innovations in the core engine benefit versions on both platforms.
The host application for AutoCAD 2012 for Mac is implemented using the Cocoa framework.
