Mac OS X 10.8 Mountain Lion was released in the Mac App Store Yesterday. Here’s how to do an upgrade install from OS X 10.7.4 Lion to Mountain Lion. If you purchased Lion from the App Store prior to May 9th, 2012, you most likely have 10.7.3. To re-download Lion and update your App to 10.7.4, simply log into the Mac App Store and click Update. When the download finishes, the app will automatically open. The updated 10.7.4 Install Mac OS X Lion App can be found in the Applications folder. The Mac App Store comes as part of the update to Mac OS X v10.6.6. The minimum system requirements for the platform are: A Mac computer with an Intel processor. Mac OS X v10.6.6 or later. Internet access. An iTunes or iCloud account.
You must upgrade to Snow Leopard 10.6.8 to access the App Store. You also must have an Intel Mac.
