[Inkscape-user] Installing Inkscape on new Macbook

Hello, I just purchased a new Macbook and have installed the Universal platform version but when I open the application I get an error message saying that I need X11 to run Inkscape. When I installed X 11 from the Apple website, I get another message saying my computer has a more recent version of this software already installed. I used Inkscape on my Dell PC and I hate to give it up now that I've switched to Mac! I'm desparate to get my Inkscape back! Any advice?

Thanks!!
