Snow Leopard sells for just £26, and Lion is even more affordable at a penny shy of £21. But if you're in this situation, you need to buy two operating systems to run the latest version of OS X Snow Leopard for the App Store, then Lion. You can then purchase, download and install Lion direct from the App Store, which can be launched from the Dock, your Applications folder or from the Apple pull-down menu.Īs Snow Leopard was so cheap, we doubt there are many Macs capable of running Lion that still using Tiger or Leopard. The App Store was introduced to Snow Leopard with the 10.6.6 upgrade, so if you're running 10.6.5 or older, run Software Update or download the combo updater from Apple's support site. This means if you're still running Leopard, or even Tiger, you must upgrade to Snow Leopard before you can install Lion.

Intel Macs with Core Duo chips cannot run it. Snow Leopard could be installed on any Intel Mac, but with Lion, you must have a Core 2 Duo, Core-i series or Xeon processor. Support for PowerPC-based Macs was dropped with OS X 10.6: Snow Leopard, so an Intel-only Lion was inevitable.Īlso inevitably, Lion makes greater demands on your computer than its predecessor. ![]() If you're going to install OS X 10.7: Lion, your Mac must meet the operating system's minimum system specs.
