NewImageAutodesk has issued a support document outlining which of its products do not work with the just-released OS X Mountain Lion:

The following products are currently NOT supported on the Mac OS X 10.8 (Mountain Lion) operating system:

- AutoCAD 2013 for Mac
- AutoCAD 2012 for Mac
- AutoCAD LT 2013 for Mac
- AutoCAD LT 2012 for Mac

If any of these products are installed on Mountain Lion, undesirable side effects can occur, including issues with Installer re-start, resetting applications, cursor missing when printing to PDF, and more. Our engineers are working round the clock to support Mountain Lion for these products, however no support is currently available.

Until such time as a service pack is available, we highly recommend NOT installing Mac OS X 10.8 (Mountain Lion) on any machines where AutoCAD 2013 for Mac, AutoCAD 2012 for Mac, AutoCAD LT 2013 for Mac, or AutoCAD LT 2012 for Mac is required.

Autodesk also says that a Beta program adding support for Mountain Lion to AutoCAD 2012 and 2013 will be coming shortly, though doesn't include any specifics about a timeline.

As always, it is recommended that those using their computers in a professional, production environment should hold off on any upgrades to either software or operating systems until the makers of all the products they use confirm that everything works as it should.

Software companies aren't used to OS makers releasing products WHEN they are announced. That's like crazy talk in the Biz.

That is for testing Autocad 2014! Silly rabbit.

Heaven forbid Autodesk have to keep up with a yearly release of an OS. I mean it's enough work getting a 2012 AND a 2013 version out... Now they have to support a new OS? The oppression !!!
