Mac OS X & Versions

Mac OS X & Versions

OS X (formally known as Mac OS X) is an Operating System designed and marketed by Apple. OS X only runs on Macintosh computers.

OS X is a UNIX-like operating system that originally ran on PowerPC-based Macs. In 2006, the first Intel Macs had a specialized version of Mac OS X v10.4 “Tiger”. in 2007, Mac OS X 10.5 “Leopard”, was the first to have UNIX 03 certification and run on both PowerPC and Intel Macs with the use of Universal Binaries. Mac OS X 10.6 “Snow Leopard” was the first version of OS X to drop support for PowerPC Macs and run solely on Intel’s x86-based processors.

Releases of OS X are named after big cats.

a Designer. a Student. a Son. a Brother. a Friend… Working as a Designer, my typical day goes all about designing. I work on Print Designs which include ads, brochures, posters, and more. I also work for Web, its not as much as compared to Print, creating webpage layouts, banners and playing with HTML and PHP sometimes.
