ND9 is only supported* in OSX 10.7 or 10.8.
I do know that 9.0.1 has Maverick fixes, but I don't have any official details on if it will be supported or not (or I'd point you to do that).
* Supported doesn't automatically mean support will not address the issue if you open a PMR. If you can reproduce the same issue on a supported platform, then it would be investigated further.
