Ok. so i knew there would be a learning curve in using inkscape and SCAL but i didn't think it would be this bad. I am trying to download inkscape onto my mac and am already doing something wrong...

My mac says i have a version 10.4.11 so downloaded Mac osx 10.4. is that right? When i try to open inkscape it says where is .11? what did i do wrong?
thanks for your help...
