Thanks for reaching out to us. I am happy to answer your question regarding OS X Mavericks/Mountain Lion compatibility with our USB 3.0 to HDMI/DVI adapter.
The biggest thing to keep in mind when trying to use any of our DisplayLink based products like the USB 3.0 to HDMI/DVI on OS X is that the experience will not be as good as that on Windows.

As to using the USB 3.0 HDMI/DVI adapter on Mavericks, there are a lot more unknowns. As of right now, DisplayLink is in the process of testing out a new driver for Mavericks, there are already some known limitations.

I would suggest that you take a look at the release notes if you would like to know more about the specific issues with DisplayLink and Mavericks:
If you have any other questions, please let me know.
