Hi nick I do use a mac but generate most of my fractals on a pc. This tells you that I feel that the pc has a better range of fractal programs. If however you only want to work on the mac then there are a number of possibilities open to you. If you have virtual pc you can look for pc fractal generation programmes that will run under it. I seem to remember someone on the apophysis beta list saying that apophysis ran fine on virtual pc. IMHO apophysis is a brilliant program and well worth a look. I must add a caveat, I have not personally run it on virtual pc so you need to check this out. There is a beta version of fractal domain that will run under osx. You can find it at the following url: http://www.fractaldomains.com/ There is a program, that I like a lot, called artmatic pro. Now this is not primarly a fractal generator. It is like an audio synthesizer where you patch components together to build modules. Some of these components are fractal in nature. Because of this you can produce fractals on it. You can also produce mixtures of fractals and other components. It will allow you to input pictures as part of a module. Hence you can create modules designed to manipulate fractal pictures. It isn't really a first fractal program niether is it cheap. You can check it out and download a trial version at the following url: http://www.artmatic.com/ Hope this helps Paul
