Start from the very beginning

This is my first time hearing about patching stuff to nba live. How do I start? Am I able to do this on a Mac?

Welcome to patching its fun, really fun. Its easy at times and hard at others.
For me I suck, so I wont be able to answer ya questions apart from, Yes you can on a Mac. From what I know anyway.

Anyways welcome buddy, you will enjoy it!
