Query: Expensive Paperweight

On a PC - this thing rocks... Cinema 4d takes some creative work arounds which is pretty lame tho - so it gets at least one star. The major disappointment however - is when you're on what is now the major player in our industry - a MAC. Absolutely no support. Wait for years - and their developers still say "Oh yeah - we've been asking companies to help us but they're busy". This is just as it sounds - pure BS.They've released a product that has become a paperweight for many people who bought it only to realize that something so unthought of is actually true: they don't support Mac OS. Crazy - but true.Very disappointing product. STAY away from all of 3dconnexion if you're a mac user. They may say they support it - but wait until you get all the fine print.
