Mac OS X is the operating system that runs on the Apple Mac hardware. The current version is 10.6, code named Snow Leopard.
Today, the new version, 10.7 "Lion", is being released.
Previously, the way to get the upgrade was to go to the store or order it online. You get a DVD, insert it into your computer, click a few times and then, voilà!
That's all changed. You can *only* buy it online via the Mac App Store that's found in Snow Leopard. This means, if you haven't upgraded to Snow Leopard already, you must do so before you can upgrade to Lion.
Also, if you have bought a Mac in the last 30-90 days, find your receipt and contact the Apple Store - you *should* be eligible for a free upgrade to Lion.
FYI, the price of Lion is about $30, just as Snow Leopard was $30.
As always, if you have any questions or concerns about this upgrade, or indeed anything computer related, let me know. Just send me a PM.
(can't wait, can't wait, can't wait!)
