Mac OS X Snow Leopard

Mac OS X Snow Leopard (version 10.6) is the seventh major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers.

Snow Leopard was publicly unveiled on June 8, 2009 at the Apple Worldwide Developers Conference. On August 28, 2009, it was released worldwide, and was made available for purchase from Apple's website and its retail stores at the price of US$29 for a single-user license. As a result of the low price, initial sales of Snow Leopard were significantly higher than that of its predecessors. The release of Snow Leopard came nearly two years after the introduction of Mac OS X Leopard, the second longest time span between successive Mac OS X releases (the time span between Tiger and Leopard was the longest).

Unlike those of previous versions of Mac OS X, the goals of Snow Leopard were improved performance, greater efficiency and the reduction of its overall memory footprint. Addition of new end-user features was not a primary consideration: its name signified its goal to be a refinement of the previous OS X version, Leopard. Much of the software in Mac OS X was extensively rewritten for this release in order to take advantage fully of modern Macintosh hardware. New programming frameworks, such as OpenCL, were created, allowing software developers to use graphics cards in their applications. This is also the first Mac OS release since System 7.1.1 that does not support Macs using PowerPC processors, as Apple now intends to focus on its current line of Intel-based products. As support for Rosetta was dropped in OS X Lion, Snow Leopard is the last version of Mac OS X that is able to run PowerPC-only applications.

OS X El Capitan

OS X El Capitan (el-KAP-ɪ-TAN) (version 10.11) is the twelfth major release of OS X, Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security. Following the California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park.

The first beta of OS X El Capitan was released to developers shortly following the 2015 WWDC keynote on June 8, 2015. The first public beta was made available on July 9, 2015. There were multiple betas released after the keynote. OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.

System requirements

All Macintosh computers that can run OS X Mavericks or Yosemite can run El Capitan, although not all of its features will work on older computers. For example, Apple notes that newly available Metal API is available on "all Macs since 2012".

Mac OS X Lion

Mac OS X Lion (version 10.7; marketed as OS X Lion) is the eighth major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers.

A preview of Lion was publicly unveiled at the "Back to the Mac" Apple Special Event on October 20, 2010. 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, as introduced in Mac OS X Snow Leopard version 10.6.6. On February 24, 2011, the first developer's preview of Lion (11A390) was released to subscribers to the Apple Developer program. Other developer previews were subsequently released, with Lion Preview 4 (11A480b) being released at WWDC 2011.

Lion was released to manufacturing on July 1, 2011, followed by its final release via the Mac App Store on July 20, 2011. Apple reported over one million Lion sales on the first day of its release.As of October 2011, Mac OS X Lion has sold over six million copies worldwide.

El Capitan (Arizona school)

El Capitan is a public school located in Colorado City, Arizona, serving students in the towns of Colorado City, Centennial Park and Cane Beds in rural Mohave County, and in Hildale, Utah. It is the only school in the Colorado City Unified School District.

History

The Colorado City Unified School District had about 1,200 pupils in 2000, when Warren Jeffs ordered Fundamentalist Church of Jesus Christ of Latter Day Saints members to pull children out of public schools. After that, the number dwindled to fewer than 250. Most of the remaining students came from the Centennial Park group. He said that it was because the curriculum was offensive to God. Sam Brower, the author of Prophet's Prey, said that the real reason was to extract money from non-believers.

The district had over 100 employees and 18 administrators at the time Jeffs ordered followers out of the school. Almost all of the employees retained their jobs with no pay cuts. Jeffs did not order the fundamentalist church members who made up the majority of the school district's administrators to quit their positions. These administrators bought cars and an aircraft before the district went into bankruptcy. The Arizona state government attempted to take over the district in 2005 due to mismanagement. The state government appointed an observer as all FLDS members of the Colorado City Board of Education left their posts. The Arizona Department of Education later concluded that the district improved after state intervention.
