Published on July 21, 2011

In case you are wondering if you need to pay $29.99 for every Mac that you own, you don’t.

Purchase a single copy using the same iTunes account, and all your authorized Macs would be able to install. This was actually mentioned in WWDC 2011 keynote.

So, go Mac App Store and download Lion now!
