The current installer for Mac failed to execute permissions as the last 
step.. 
So to make "Penrose Studio.app" double clickable, you need to execute 
this: 

sudo chmod a+x /Applications/Penrose\ Studio/Penrose\ Studio.app/Contents/MacOS/* 

We are going to work on a DMG-based installer for Penrose Studio that is native to Mac OS X.

We created a DMG-based installer. To install Penrose Studio, you just simply mount the dmg and drag/drop the Penrose Studio to your Applications Folder.

This is fixed. Macos X has a separate installer that is based on DMG
