UBUNTU 10.10 64 bit:
It installs perfectly on ubuntu. Open GL won't work, use directx 9. There re little bugs, but it sees graphic card & works very fast. I wish I could manage to work version 9 as well on ubuntu.
Rank: I have to say silver. There are a little bugs when u re doing animations. it looks like almost all original plugins works well. rendering without a problem.
MAC OS X:
software don't recognises graphic card, also animation screen is hell like buggy, u need to work blindly then refresh page for see what u have done. I believe it's because X11. If 3ds max see the graphic card, I think mac os x will become greatest animation os of all time.
Rank: installs, opens, renders work. Screen & graphic card bug is very bad. but if it's working somehow, I have to say it's bronze(hardly)
