File Quarantine
Gatekeeper is a security feature of the macOS operating system by 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 and expanded in Mac OS X Snow Leopard. The feature originated in version 10.7.3 of Mac OS X Lion as the 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. Quarantine Upon download of an application, a particular extended file attribute ("quarantine flag") can be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer 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 Xerox PARC Xerox Alto, Alto computer, which ...

Mac App Store
The App Store (also known as the Mac App Store) is a digital distribution platform for macOS apps, often referred to as Mac apps, created and maintained by Apple Inc. 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. As of June 2019, the membership fee is US$99 a year. Apps must be approved by Apple before becoming available on the store. Disallowed types of apps revealed by Apple include apps that: * change the native user int ...

Disk Image
A disk image, in computing, is a computer file containing the contents and structure of a disk volume or of an entire data storage device, such as a hard disk drive, tape drive, floppy disk, optical disc, or USB flash drive. A disk image is usually made by creating a sector-by-sector copy of the source medium, thereby perfectly replicating the structure and contents of a storage device independent of the file system. Depending on the disk image format, a disk image may span one or more computer files. The file format may be an open standard, such as the ISO image format for optical disc images, or a disk image may be unique to a particular software application. The size of a disk image can be large because it contains the contents of an entire disk. To reduce storage requirements, if an imaging utility is filesystem-aware it can omit copying unused space, and it can compress the used space. History Disk images were originally (in the late 1960s) used for backup and disk clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 1991 ...

Trash (computing)
In computing, the trash is a graphical user interface desktop metaphor for temporary storage for files set aside by the user for deletion, but not yet permanently erased. 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. In the file manager, the trash can be viewed by the user as a special 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 to undelete those that were deleted by mistake. In macOS, the Trash folder links to hidden folders on each mounted drive where the files are actually stored. Within a trash folder, a record may be kept of each file and/or directory's original location, depending on the implementation. On certain operating systems, files must be moved out of the ...

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 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 base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
