I am new to the Mac System so I need advice concerning OSX downloads. Is the OS download the same for both the Notebooks and Desktops? I know the drivers are going to be different, so I'm wondering if the OS will contain the drivers for both. I'm asking this because I placed Snow Leopard, Lion, and Mountain Lion on individual Flash drives using my 2009 vintage MacMini. I plan on fully updating a friend's Macbook with one of these. Thank You.
