Do I need to upgrade my Rhino 5.5.2 for Mac

Hi, having a lot of problems using properties - model materials to render individual (selected) objects / layers. Not sure if this is because I don’t know how to or because I need to upgrade my Rhino.
Please can you advise me, if my Rhino’s ok then please point me to relevant tutorial / documentation.
Do you recommend upgrading to Rhino 6 for Mac?
Thanks
David

Rhino 6 for Mac is in a WIP stage, which means it is free to download and use as long as you have a V5 license, it is still no where near the finished product, use at your own peril :crazy_face:

you can find it here

probably wise to read this too

Thanks for this, I understand upgrading will not solve my current problem using Properties - Material Model to render individual objects / layers. Do you know of any tutorials that may help me?
Thanks
David
