General Information about Mac OS X Lion (10.7)


In July, 2011, Apple released the newest version of it Mac OS X operating system, Mac OS X Lion. This new version has all of the old features that Mac users expect as well as some new ones that make OS X Lion enjoyable and more useful. 


Multi-Touch Gestures—This takes the gestures that we have all become accustomed to using our iPods and iPhones and transports them to your computer. To zoom in or out you either pinch or expand two fingers. You can also navigate your web browser by swiping two fingers from side to side. 

Full Screen Apps—Have you ever been trying to write a paper or read a long article for class but get distracted by programs running in the background? Well now you don't have to. With full screen apps you have the ability ot make programs take up the entire screen limiting the number of distractions visable to you while you work. 

Mission Control—This feature allows you to zoom out of your desktop and see all the windows currently running on your mac and switch between the seamlessly with a single click. 

Resume—This may be the single most innovative feature in OS X Lion. It allows you to restart a program or your computer with all the screens running that were running before you restarted. This means that there is no longer a need to shut everything down for system updates because after it restarts the windows that you had open previously will be wating for you. 

System Requirements
