Which is why human App Reviewers ensure that the apps on the App Store adhere to our strict app review standards.Is it possible to install the app store from another source? Could I do a factory reset without my startup disks? Or could I just purchase and install OS X Lion and upgrade from there? Also, my start up disks were lost in my last move, so reinstalling snow leopard to regain the app isn't an option. Apparently, I cannot access the store without the app to download any upgrades. I would like to upgrade my OS from 10.6.8, however the APP Store application is missing from my computer.
