Rhino MAC - Standard Materials are not available

After buying Rhino for Mac and a new Installation (old one was deleted), the materialbrowser lost all the pictures for material. I am also not able to find the folder for standard material on my mac. how can i install the standard materials and where do I get them for download?

in this example the texture cherry.png is missing

I see that you are using a German version - see this discussion:

Hi Wim,
thank you for your answer - this is exactly the problem I have. I can confirm, if I change the Language to English, the materialbrowser works fine and no more missing textures. I will wait for an update.
thank you so much - marc
