Apple’s latest release of Mac OS X 10.7 – also known as Lion – brings with it some really interesting changes, such as gesture controls, an iPad inspired menu, and an easy way of sharing files wirelessly between Macs. But with Snow Leopard cited as one of the basic requirements for Lion, how do you install the new OS if you’ve got a really old Mac?

If you’ve got 10.6 – Snow Leopard – the upgrade path is really easy. All you need to do is visit the App Store on your Mac and grab a copy of Lion, priced at$31.99, effectively giving you an easy upgrade path.

But if you’ve got a version of Mac OS that’s below 10.6 – such as 10.5 “Leopard”  or 10.4 “Tiger” – you’ll need to head to Apple’s store (either online or in person) and grab a physical disc to install Snow Leopard before you install Lion.

Once you’ve installed 10.6, you can grab Lion from the Mac App Store and upgrade like everyone else.
