title: Install SQL Developer mac osx 10.9.1
body: <p>i'm trying to install Oracle's SQL Developer in my macbook pro OSX 10.9.1 but I can't understand how to do it. I download a .gz file which I unzip to get an installer but all I have is an unknown file called sqldeveloper-4.0.0.13-1.80-macosx. It is not a .dmg or something so i don't know what to do whith it.</p>
  
  <p>I've read that i'm supposed to run over the extracted directory something like sh sqldeveloper.sh from the terminal but that file isn't there, just the one mentioned above.</p>
  
  <p>thanks</p>
