ohh....... well ur only left with BLENDER, that is the only sculpting thingie for mac!!!!
try to type some form of english/americanish?
what is so called "ur" sounds like er, and what's a "thingie"? do you mean thingy?
and macs are weird, but you should be able to replace the text in the script, and not sure if modeling programs still work on macs, i bet they do though
