These types of files literally take over your disk space so they need to be disposed, and that is what Ccleaner is for. For those who are very familiar of Ccleaner, it's a free utility software that clears all unnecessary junk files to free up hard disk space, especially cache files or temporary internet files. Windows users have it very easy because they have Ccleaner. The purpose of course is to make our Mac work smoothly and efficiently. As of October 2011, Mac OS X Lion has sold over 6 million copies worldwide.

Apple reported over 1 million Lion sales on the first day of its release. Lion achieved golden master status on July 1, 2011, followed by its final release via the Mac App Store on July 20, 2011. Other developer previews were subsequently released, with Lion Preview 4 being released at WWDC 2011. On February 24, 2011, the first developer's preview of Lion was released to subscribers of Apple's developers program.

It brings many developments made in Apple's iOS, such as an easily navigable display of installed applications, to the Mac, and includes support for the Mac App Store. Mac OS X Lion (version 10.7 marketed as OS X Lion) is the eighth and current major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers.Ī preview of Lion was publicly unveiled at Apple's 'Back to the Mac' event on October 20, 2010.
