If you want to upgrade your Mac to OS X Lion, you don’t have to worry about going to the store and having to install a bunch of discs from a box; you can just go to the Mac App Store and buy Lion for $29.99. You also need to prepare your Mac for Lion. Your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor for your Mac to be able to run Lion. You can check to see what processor your Mac has by clicking the Apple icon on the top left of your display and choosing About This Mac. Your Mac must also be up to date with the latest version of OS X Snow Leopard. Click the Apple icon and choose Software Update to install version 10.6.8 if you haven’t done so already. After you have done those steps, you can open the Mac App Store and purchase OS X Lion.
There have been questions about the pricing and availability of OS X Lion to business customers and education customers. Apple decided to give business users Volume License contracts at the same $29.99 per license with a minimum of 20 users. Maintenance contracts for extra support will be available for $49.99 with a minimum of 20 users. For education customers, Lion will be included in the Apple Software Collection. The Apple Software Collection will contain Mac OS X Lion, iLife, and iWork for $39 per license with a minimum of 25 licenses.
You are still able to use the same mass installation techniques people use today to deploy Mac OS X. To install Lion on multiple systems on a network, you can simply copy the Install Mac OS X Lion application to the target system and run the installer. Administrators will also be able to use the System Image Utility included in OS X Lion Server to create a NetInstall or NetRestore image.
If you bought a Mac on or after the June 6, 2011, you are eligible to request an up-to-date upgrade. The upgrade will allow you to upgrade to Lion for free. You must request your Up-to-Date upgrade within 30 days of purchasing a new Mac computer.
