Why I made this
The non-steam version of Borderlands 2 works perfectly fine on Snow Leopard, but the steam version won't launch unless you have at least Mac OS 10.7.5! BLEH! I was stubborn about updating past 10.6.8 (Snow Leopard) but I stillwanted to play Borderlands 2 on Steam. So I made this script to trick Steam into thinking I was running a newer version of OSX, which allowed Borderlands 2 to run in Steam just fine!
SUCCESS!

REMEMBER TO RUN THIS SCRIPT AGAIN TO CHANGE YOUR VERSION BACK TO 10.6.8 WHEN YOU ARE DONE PLAYING BORDERLANDS!
That means: run this script again but instead of choosing option 2, choose option 1. That's it!
Some programs will not launch while your system version has been hacked, you will get errors that give you the impression things have been corrupted/damage. Do not worry, you just need to revert your system version back to the way it was.
You might run into problems if you reboot the computer while your system version has been hacked, but I have never encountered an unbootable state by using this method/script.
