If you haven't already heard, we've recently re-released AutoCAD for Mac 2013 and AutoCAD LT for Mac 2013 to combat former compatibility issues with Yosemite.
Please see the following links depending on your product:
AutoCAD for Mac 2013
AutoCAD LT for Mac 2013
This is better late than never we hope! If you have any trouble with the fresh installation, be sure to create a post on our Installation and Licensing board.
If you need any additional help, please visit us on Twitter @Autodeskhelp or if you have any other product specific questions please post a new message in one our Autodesk Community forums.
