Hello, Since I own an iPhone, my boss has decreed that I am to become The Guy when it comes to the 5 Mac computers we have here in our company. Because we're mostly Windows based (and it will stay that way), the Macs are pretty much taken care of by hand, which means I will be responsible for upgrading their software when needed. They all run Leopard (10.5.6), but I'd like to get them up to Snow Leopard. My question is this: Is it possible to get a stand-alone, fresh-install license for Snow Leopard, instead of the 29 upgrade? If something were to happen to the machine and it needed to be reinstalled, would I need to have the old license for 10.5.6 or would I simply be able to wipe the drive completely clean and install the upgrade without any preexisting OS or without having to insert an old disc or something like that?
