All the 3 Tomato Builds for mac CRASH for me ¿?

So , i got a macbookpro from 1 year ago, osx 10.5.8,

then i go to graphicall.org, search tomato for mac…

they appear 3 builds, i download then, they finish downloading and they unzip into a blender icon , i press them and :

Crash

with all of them , what am i doing wrong ?

Anyone, experiences on mac ?

No crashes specifically with Tomato or Salad builds. OSX 10.6 or 10.7
