spangfract works in the classic mode of OS X and with OS 9 ... you can actually use M$ Virtual PC on the mac, get Ultra Fractal and other wintel programs to get working, but on a 800MHz Mac it reduces the speed and acts like a PII 366MHz ... for OS X i recommend the program i use, which is artmatic from UI Software, which fractals are easy to import to photoshop for it generates PCT files ... the program artmatic also has the ability to import photo's ,,, and if the man in question isn't all mac minded like i am, he can connect a wintelly to the mac, and share the files merry xmas Harmen
