Apple launched the ninth version of its Mac operating system, OS X Mountain Lion Wednesday.

Apple previously revealed the OS X 10.8 in June at its annual Worldwide Developers Conference (WWDC) where the company shared what some of the system's offerings would be, priced the system at $19.99, and left consumers at the edge of their seats, saying that it would ship sometime during the summer, but giving no specifics.

The operating system is made accessible through download from Apple's online store. Mac users can go about downloading it using Apple's app store Wi-Fi network or do so through public hotspots.

To use Mountain Lion user must have a Mac with an Intel Core 2 Duo, Core i3, Core i5, Core i7 or Xeon processor, however some of the machines do not allow updating. Those using Snow Leopard dated prior to June 2011 have to update their devices before attempting to use the Mac App Store.

Customers are now able to request free copies of Mountain Lion from Apple if they bought a new Mac on or after June 11.

For those who do not qualify for free copies, the price is reasonable, costing less than what it was for last year's Lion.

Downloading Mountain Lion is made easy through a three-step guide of how the upgrade works, which can be found on Apple's site.
