Curious Labs can use a big cash infusion right now, but it's a bad time economics-wise. Hi-tech investment is flat (or still dropping) in that area. If there's no Mac version, it's understandable. The amount of profit associated with Mac sales (about 4% of total) is probably not even enough to pay the programmers in India or Israel, so where are they going to get the money and how are they going to justify the expense? I just don't see it, frankly. They're on a shoestring budget as it is. It's the same thing that happened with UVMapper Pro. They did the math and the numbers weren't good enough to proceed with a Mac version, then OSX came along and made everything 10 times harder for them.
