Since I have a Mac I have to use a virtual machine to run Windows on it. I have Parallels and ri-un Windows XP. It works well and I can use Apo or FE etc. Still it's a bother to open and I prefer Mac programmes like UF for Mac. Apo is so slow to render, I've no patience with it any more. FE is not as nice as UF.
My Mac is an older version. I could update it easily for only a little expense. I must get round to it one of these days. It's not very expensive.
well dunno... i use chaotica mostly as a renderer for apo flames (its compatible for 2d stuff, faster and better render quality)... And well dunno about the version, im not very fond of macs due to compatibility issues =/
