OK folks, are you ready to upgrade your Mac OS X Snow Leopard to Lion? I think you have to update your software first before you can upgrade to Mac OS X Lion! See that Apple icon on very top left of your screen? Click on that and move down till you see Software Update, and click on that to update your software. Done? Go check Apple App Store to see if Mac OS X Lion is ready for you to download (i.e., purchase). The news is all over the web that Apple will release Mac OS X Lion today (July 20th, 2011).
Alright, go upgrade your Mac to Mac OS X Lion! Have fun!
