I grabbed my dad's 2ghz white MacBook thinking I would upgrade it to lion for him, but.... the App store is missing. It's not in the dock, it's not in the applications folder, and I can't find it with spotlight. It's running 10.6.8, and I just went and updated all the software and still no signs of the App store. Any idea how I can get it on this machine? Or will it just not work on a late 2007 macbook (3,1)?
