Gatekeeper (Mac OS X)
Gatekeeper is a security feature of the macOS operating system by Apple Inc., Apple. It enforces code signing and verifies downloaded applications before allowing them to run, thereby reducing the likelihood of inadvertently executing malware. Gatekeeper builds upon File Quarantine, which was introduced in Mac OS X Leopard (10.5) and expanded in Mac OS X Snow Leopard (10.6). The feature originated in version 10.7.3 of Mac OS X Lion as the Console application, command-line utility . A graphical user interface was originally added in OS X Mountain Lion (10.8) but was backported to Lion with the 10.7.5 update. Functions Configuration In the security & privacy panel of System Preferences, the user has three options, allowing apps downloaded from: The command-line utility provides granular controls, such as custom rules and individual or blanket permissions, as well as an option to turn Gatekeeper off.

Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Mac (computer), Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the PARC (company), Xerox ...

Mac App Store
The Mac App Store (also known as the App Store) is a digital distribution platform for macOS apps, often referred to as Mac apps, created and maintained by Apple. The platform was announced on October 20, 2010, at Apple's "Back to the Mac" event. Apple began accepting app submissions from registered developers on November 3, 2010, in preparation for its launch. The Mac App Store was launched on January 6, 2011, as part of the free Mac OS X 10.6.6 update for all current Snow Leopard users. After 24 hours of release, Apple announced that there were over one million downloads. Regulations Like the App Store on iOS and iPadOS, the Mac App Store is regulated by Apple. To submit an app for consideration, the developer must be a member of the Apple Developer Program. the membership fee is US$99 a year.

Disk Image
A disk image is a snapshot of a storage device's content typically stored in a file on another storage device. Traditionally, a disk image was relatively large because it was a bit-by-bit copy of every storage location of a device (i.e. every sector of a hard disk drive), but it is now common to only store allocated data to reduce storage space. Compression and deduplication are commonly used to further reduce the size of image files. Disk imaging is performed for a variety of purposes including digital forensics, cloud computing, system administration, backup, and emulation for digital preservation strategy. Despite the benefits, storage costs can be high, management can be difficult and imaging can be time consuming. Disk images can be made in a variety of formats depending on the purpose. Virtual disk images (such as VHD and VMDK) are intended to be used for cloud computing, ISO images are intended to emulate optical media, such as a CD-ROM. Raw disk images are use ...

Context Menu
A context menu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which the menu belongs. Usually the available choices are actions related to the selected object. From a technical point of view, such a context menu is a graphical control element. History Context menus first appeared in the Smalltalk environment on the Xerox Alto computer, where they were called ''pop-up menus''; they were invented by Dan Ingalls in the mid-1970s. Microsoft Office v3.0 introduced the context menu for copy and paste functionality in 1990. Borland demonstrated extensive use of the context menu in 1991 at the Second Paradox Conference in Phoenix Arizona. Lotus 1-2-3/G for OS/2 v1.0 added additional formatting options in ...

Trash (computing)
In computing, the trash, also known by other names such as trash bin, dustbin, wastebasket, and similar names, is a graphical user interface desktop metaphor for temporary storage for computer file, files set aside by the user for deletion, but which are not yet permanently erased. This lifts the burden from the user of having to be highly careful while selecting files for deletion, since a trash bin provides a grace period to reverse unwanted deletions. The concept and name is part of Mac operating systems; a similar implementation is called the Recycle Bin in Microsoft Windows, and other operating systems use other names, sometimes suffix, ending with "-bin". In the file manager, the trash can be viewed by the user as a special Directory (computing), file directory, allowing the user to browse the files and retain those still wanted before deleting the others permanently (either one by one, or via an "empty trash" command). It may still be possible using third party software t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gatekeeper Alert
A gatekeeper is a person who controls access to something, for example via a city gate or bouncer, or more abstractly, controls who is granted access to a category or status. Gatekeepers assess who is "in or out", in the classic words of management scholar Kurt Lewin. Various figures in the religions and mythologies of the world serve as gatekeepers of paradisal or infernal realms, granting or denying access to these realms, depending on the credentials of those seeking entry. Figures acting in this capacity may also undertake the status of watchman, interrogator or judge. In the late 20th century the term came into more metaphorical use, referring to individuals or bodies that decide whether a given message will be distributed by a mass medium. Gatekeeping roles Gatekeepers serve in various roles including academic admissions, financial advising, and news editing, along with many areas of the fine arts. An academic admissions officer might review students' qualifications b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macworld
''Macworld'' is a digital magazine and website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG. History ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It began as a print magazine in 1984, with its first issue distributed at the launch of the Macintosh computer. As a print magazine, it had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, '' MacLife''. In 1997, the Ziff-Davis-owned '' MacUser'' magazine was consolidated into ''Macworld'' within the new Mac Publishing joint venture between IDG and Ziff-Davis. In 1999, the combined company also purchased the online publication MacCentral Online, because ''Macworld'' did not have a powerful online news component at the time. In late 2001 IDG bought out Ziff-Davis' share of Mac Publishing, making it a wholly-owned subsidiary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (BitTorrent Client)
Transmission is a BitTorrent client which features a variety of user interfaces on top of a cross-platform back-end. Transmission is free software licensed under the terms of the GNU General Public License, with parts under the MIT License. Features Transmission allows users to quickly download files from multiple peers on the Internet and to upload their own files. By adding torrent files via the user interface, users can create a queue of files to be downloaded and uploaded. Within the file selection menus, users can customise their downloads at the level of individual files. Transmission also seeds, that is, it will automatically share downloaded content. Transmission allows the assigning of priorities to torrents and to files within torrents, thus potentially influencing which files download first. It supports the Magnet URI scheme and encrypted connections. It allows torrent-file creation and peer exchange compatible with Vuze and μTorrent. It includes a built-i ...

BitTorrent
BitTorrent is a Protocol (computing), communication protocol for peer-to-peer file sharing (P2P), which enables users to distribute data and electronic files over the Internet in a Decentralised system, decentralized manner. The protocol is developed and maintained by Rainberry, Inc., and was first released in 2001. To send or receive files, users use a Comparison of BitTorrent clients, BitTorrent client on their Internet-connected computer, which are available for a variety of computing platforms and Comparison of BitTorrent clients#Operating system support, operating systems, including BitTorrent (software), an official client. BitTorrent trackers provide a list of files available for transfer and allow the client to find peer users, known as "seeds", who may transfer the files. BitTorrent downloading is considered to be faster than HTTP ("direct downloading") and File Transfer Protocol, FTP due to the lack of a central server that could limit bandwidth.

Email Client
An email client, email reader or, more formally, message user agent (MUA) or mail user agent is a computer program used to access and manage a user's email. A web application which provides message management, composition, and reception functions may act as a web email client, and a piece of computer hardware or software whose primary or most visible role is to work as an email client may also use the term. Retrieving messages from a mailbox Like most client programs, an email client is only active when a user runs it. The common arrangement is for an email user (the client) to make an arrangement with a remote Mail Transfer Agent (MTA) server for the receipt and storage of the client's emails. The MTA, using a suitable mail delivery agent (MDA), adds email messages to a client's storage as they arrive. The remote mail storage is referred to as the user's mailbox. The default setting on many Unix systems is for the mail server to store formatted messages in mbox, within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Browser
A web browser, often shortened to browser, is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers can also display content stored locally on the user's device. Browsers are used on a range of devices, including desktops, laptops, tablets, smartphones, smartwatches and consoles. As of 2024, the most used browsers worldwide are Google Chrome (~66% market share), Safari (~16%), Edge (~6%), Firefox (~3%), Samsung Internet (~2%), and Opera (~2%). As of 2023, an estimated 5.4 billion people had used a browser. Function The purpose of a web browser is to fetch content and display it on the user's device. This process begins when the user inputs a Uniform Resource Locator (URL), such as ''https://en.wikipedia.org/'', into the browser's address bar. Virtually all URLs on the Web start with either ''http:'' or ''h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
