MacBook Version?

[Steve~Jobs]

I have a MacBook air that is: Mac OS X 10.6.8

I clicked on the software hardware update and everything is up to date.

However when I go to download an app in the App store it says it can't be downloaded because "Mac OS X version 10.7.2 or later is required"

How do I upgrade to that?

You have to buy Lion (10.7) from the Mac App Store. It's an upgrade, not an update.

Software update, upgrade--what's the difference?

Probably slow it down a bit, as Mac OS X 10.7 Lion is a bit hungry for RAM, thus 4 GB RAM might be better.

It depends on what applications you run. As you've already experienced, some apps won't run on earlier versions of Mac OS X, and some may not run on Lion. You have to do some homework and read some of the many existing threads on Lion to find out if it's best for your needs.
