Inoperable materials

it has been a while since this one was brought up. Anyway, I am wondering if there will be any improvement in handling several materials in Rhino for Mac? I have 20-30 materials (Rhino materials) and the model is quite laggy. What is worse, the material panel is just painfully slow. Sometimes it takes 20-30 sec, just waiting for opening this panel, assigning material is another round. Can you confirm the same behaviour or is it only my Mac here? With an increasing number of materials, it is just becoming absolutely unusable…

This sounds very slow… not the case with my RH for Mac. I mean it is not blazing fast yet, but definitely usable. You could provide a sample file, then I could check that with my machine.
