MacOS Sierra
macOS Sierra (version 10.12) is the thirteenth major release of macOS (formerly known as and ), Apple Inc.'s desktop and server operating system for Macintosh computers. The name "macOS" stems from the intention to uniform the operating system's name with that of iOS, watchOS and tvOS. Sierra is named after the Sierra Nevada mountain range in California and Nevada. Its major new features concern Continuity, iCloud, and windowing, as well as support for Apple Pay and Siri. The first beta of macOS Sierra was released to developers shortly following the 2016 WWDC keynote on June 13, 2016. The first public-beta release followed on July 7, 2016. It was released to end users on September 20, 2016, as a free upgrade through the Mac App Store and it was succeeded by macOS High Sierra on September 25, 2017. System requirements macOS Sierra requires at least 2 GB of RAM and 8 GB of storage space and is designed to run on the following products: *iMac (Late 2009 or later) * MacBook ...

MacOS
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac computers. Within the market of desktop and laptop computers it is the second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X 10.7 Lion. Apple's other operating systems (iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS. A promi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Po ...

MacBook Air
The MacBook Air is a line of ultrabook computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, and, in the more modern versions, a thin light structure. The Air was originally positioned above the previous MacBook line as a premium ultraportable. Since then, the original MacBook's discontinuation in 2011, and lowered prices on subsequent iterations, have made the Air Apple's entry-level notebook. In the current product line, the MacBook Air is situated below the performance range MacBook Pro. The Intel-based MacBook Air was introduced in January 2008 with a 13.3-inch screen, and was promoted as the world's thinnest notebook, opening a laptop category known as the ultrabook family. Apple released a second-generation MacBook Air in October 2010, with a redesigned tapered chassis, standard solid-state storage, and added a smaller 11.6-inch version. Later revisions added Intel Core i5 or i7 processors and Thunderbolt. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IMac (Intel-based)
The Intel-based iMac is a discontinued series of Macintosh all-in-one desktop computers designed, manufactured and sold by Apple Inc. from 2006 to 2022. While sold, it was one of three desktop computers in the Macintosh lineup, serving as an all-in-one alternative to the Mac Mini, and sat below the performance range Mac Pro. It was sold alongside the Xeon-based iMac Pro from 2017 to 2021. Pre-2009 iMac models featured either a white polycarbonate enclosure or an aluminum enclosure. The October 2009 iMac model featured a unibody aluminum enclosure, a version of which could had been seen on the latest models before the launch of the Apple silicon colourful iMacs. The iMacs released in October 2012 also featured a much thinner display, with the edge measuring just 5 mm. The Intel-based iMac was succeeded by the iMac with Apple silicon beginning in 2021 as part of the Mac transition to Apple silicon. On April 20, 2021, Apple discontinued the 21.5-inch Intel iMac with 4K Retin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random-access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working Data (computing), data and machine code. A Random access, random-access memory device allows data items to be read (computer), read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older Magnetic tape data storage, magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexer, multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gigabyte
The gigabyte () is a multiple of the unit byte for digital information. The prefix ''giga'' means 109 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid state drives, and tapes, as well as data transmission speeds. However, the term is also used in some fields of computer science and information technology to denote (10243 or 230) bytes, particularly for sizes of RAM. Thus, prior to 1998, some usage of ''gigabyte'' has been ambiguous. To resolve this difficulty, IEC 80000-13 clarifies that a ''gigabyte'' (GB) is 109 bytes and specifies the term ''gibibyte'' (GiB) to denote 230 bytes. These differences are still readily seen for example, when a 400 GB drive's capacity is displayed by Microsoft Windows as 372 G ...

End User
In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, Information technology (IT) experts, software professionals and computer technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact easily overlooked and forgotten by designers: leading to features creating low customer satisfaction. In information technology, end users are not "customers" in the usual sense—they are typically employees of the customer. For example, if a large retail corporation buys a software package for its employees to use, even though the large retail corporation was the "customer" which purchased the software, the end users are the employees of the company, who will use the software at work. Certain American defense-related pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Worldwide Developers Conference
The Worldwide Developers Conference (WWDC) is an information technology conference held annually by Apple Inc. The conference is usually held at Apple Park in California. The event is usually used to showcase new software and technologies in the macOS, iOS, iPadOS, watchOS, and tvOS families as well as other Apple software. WWDC is also an event hosted for third-party software developers that work on apps for iPhones, iPads, Macs, and other Apple devices. Attendees can participate in hands-on labs with Apple engineers and attend in-depth sessions covering a wide variety of topics. The first ever WWDC was held in 1983 with the introduction of Apple Basic, but it was not until 2002 that Apple started using the conference as a major launchpad for new products. Beginning in 1987, WWDC was held in Santa Clara. After 15 years in nearby San Jose, the conference moved to San Francisco, where it eventually became Apple's primary media event of the year and regularly sold out. WWDC retur ...

Siri
Siri ( ) is a virtual assistant that is part of Apple Inc.'s iOS, iPadOS, watchOS, macOS, tvOS, and audioOS operating systems. It uses voice queries, gesture based control, focus-tracking and a natural-language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. With continued use, it adapts to users' individual language usages, searches and preferences, returning individualized results. Siri is a spin-off from a project developed by the SRI International Artificial Intelligence Center. Its speech recognition engine was provided by Nuance Communications, and it uses advanced machine learning technologies to function. Its original American, British and Australian voice actors recorded their respective voices around 2005, unaware of the recordings' eventual usage. Siri was released as an app for iOS in February 2010. Two months later, Apple acquired it and integrated into iPhone 4S at its release on ...

Apple Pay
Apple Pay is a mobile payment service by Apple Inc. that allows users to make payments in person, in iOS apps, and on the web. It is supported on these Apple devices: iPhone, Apple Watch, iPad, and Mac. It digitizes and can replace a credit or debit card chip and PIN transaction at a contactless-capable point-of-sale terminal. It does not require Apple Pay-specific contactless payment terminals; it can work with any merchant that accepts contactless payments. It adds two-factor authentication via Touch ID, Face ID, PIN, or passcode. Devices wirelessly communicate with point of sale systems using near field communication (NFC), with an embedded secure element (eSE) to securely store payment data and perform cryptographic functions, and Apple's Touch ID and Face ID for biometric authentication. Apple Pay can also be used to ride some public transport networks either through the use of credit/debit cards (open loop) (for example across TfL in London, SL in Stockholm, and at OM ...
