How is this the solution or any real resolution? 

It's not compatible with Yosemite?? Well I already upgraded my Mac to Yosemite. I can't go back to the old OS. And I guess I can't upgrade my Autocad LT 2013? But I alerady can't really use it because it crashes SO OFTEN. 5 times in the past hour. It's almost hopeless.

AUTODESK I need a solution to this problem!! How can I get Autocad to work properly again on my Mac with Yosemite??
