I have read on the Apple site about how to return the mac to factory settings. It's not something that I need to do at the moment but I was interested in how to do it and it all seems pretty straight forward. The only thing I was wondering is this: On the Apple site it says to install the snow leopard disc first followed by the applications disc which will install the bundled applications that came with a new mac. Well, I've got 3 discs that came with my macbook, snow leopard, applications and ilife. So what's on the applications disc and if it's Ilife why have I got an extra disc specifically with Ilife on it?
