Hey guys, I have a 2010 13" MBP, and I would like to do a fresh install of OSX. Now I don't have my CD where I'm staying at the moment, so I would like to use a colleague's who just bought a 2010 17" MBP. Will I need some sort of license code, or can I just use his CD to do a clean install? Also, if I need a license, is it possible to extract it from my mac in a way? I hope somebody can help me with this.
