I would like to install the open-source vector design program called "Inkscape" on my new MBP, but it says that it requires "XQuartz"?! This leads me to many questions... 1.) Is XQuartz safe to install? 2.) Why aren't Inkscape and Mountain Lion compatible without XQuartz? (Makes either Mountain Lion or Inkscape seem "outdated"...) 3.) If XQuartz is safe, then do I need anything special to install it on Mountain Lion? (e.g. Developer Account, $$$, etc.) 4.) Where is the safest source to download XQuartz? 5.) Anything else that I should know or take into account before I "take the leap" and install XQuartz onto my new baby?! Sincerely, Debbie P.S. Does anyone use Inkscape, and if so, what do you think about it?!
