How i change the shortname on a 2007 Macbook Pro
So I have received my friends 2007 MacBook pro and need to change the shortname to my own. Now I had previously a 2010 MacBook pro, and I'm now learning that most of my newer software that was on there is not compatible with this computer, so I have to upgrade the system to snow leopard. Do I need to change the shortname before I upgrade to the snow leopard or will I be able to do so once I reinstall? Yes I am down grading, from a 2010 MacBook pro to a 2007 MacBook Pro its not a typo.
MacBook Pro, Mac OS X (10.5.8)
