It's the Bryce program that is important, not which OS it is running on, although I do sympathise with Mac users for being let down by Corel. But if we all have a great love for this little app then we all got to pull together so that in the future people can still buy Bryce and fall in love with it too. I'm just a big sentimental thing, ie. falling in love with inanimate objects, or 3ds, or cob, or lwo, etc. etc. 8) Catlin
