Im buying a used MBP and Im worried that there may be pirated software on it. Its coming with the latest OSX and Aperture 3 installed, but no discs. This will be my first time using OSX so Im not familiar with how things work. I know on my PC when I connect to windows update I am able to see if the operating system is genuine or not. Since both Aperture 3 and OSX are Apple products is there a way I can connect to the internet and verify they are not pirated before purchasing?
