Repair Permissions
Repairing disk permissions is a troubleshooting activity commonly associated with the macOS operating system by Apple. The efficacy of repairing permissions to troubleshoot application errors has been debated. Overview The BSD layer in macOS is responsible for file-system security, including the management of the Unix (POSIX) permissions model. Applications depend on the correct assignment and interpretation of permissions in order to function properly. Repairing permissions involves checking the permissions of a set of files and folders on a volume with macOS installed against a list of correct POSIX permissions and correcting any discrepancies. The list of correct permissions is compiled by consulting the various bill-of-materials (.bom) files. Typically, these files are stored within reduced-size Installer package (.pkg) files in the Receipts folder in the local Library directory () on the volume being checked. Whenever a user installs software that uses the macOS Installer p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troubleshooting
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state. A strategy is an organized set of activities expressing a plausible way of achieving a goal. Strategies should not be viewed as algorithms, inflexibly followed to solutions. Problem solvers behave opportunistically, adjusting activities within a strategy and changing strategies and tactics in response to information and ideas. Diagnostics In general, troubleshooting is the identification or diagnosis of "trouble" in the management flow of a sys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Third-party Software Component
In computer programming, a third-party software component is a reusable software component developed to be either freely distributed or sold by an entity other than the original vendor of the development platform. The third-party software component market is supported by the belief that component-oriented development improves efficiency and quality when developing custom applications. Common third-party software includes macros, bots, and software/scripts to be run as add-ons for popular developing software. In the case of operating systems such as Windows XP, Vista or 7, there are applications installed by default, such as Windows Media Player or Internet Explorer. See also * Middleware * Enterprise Java Beans * VCL / CLX * KParts (KDE KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that enable collaborative work on its projects. Its products include the KDE Plasma ...

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 unify 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. Specifically, Lone Pine Peak is the location for macOS Sierra's default wallpaper. Its major new features concern Continuity, iCloud, and windowing, as well as support for Apple Pay and Siri.

System Partition And Boot Partition
The system partition and the boot partition (also known as the system volume and the boot volume) are computing terms for disk partitions of a hard disk drive or solid-state drive that must exist and be properly configured for a computer to operate. There are two different definitions for these terms: the common definition and the Microsoft definition. Common definition In context of every operating system, except those developed by Microsoft, the system partition and the boot partition are defined as follows: * The ''boot partition'' is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. For example, in the standard Linux directory layout (Filesystem Hierarchy Standard), boot files (such as the Linux kernel, kernel, initrd, and boot loader GRUB) are mounted at /boot/. Despite Microsoft's radically different definition (see below), System Information, a utility app included in Windows NT family of operating systems, ...

Console Application
A console application or command-line program is a computer program (applications or utilities) designed to be used via a text-only user interface. A console application can be used with a computer terminal, a system console, or a terminal emulator included with a graphical user interface (GUI) operating system, such as the Windows Console in Microsoft Windows, the Terminal in macOS, and xterm in the X Window System on Unix-like systems. Console applications can be run from a command-line shell. Overview A user typically interacts with a console application using only a keyboard and display screen, as opposed to GUI applications, which normally require the use of a mouse or other pointing device. Many console applications such as command line interpreters are command line tools, but numerous text-based user interface (TUI) programs also exist. As the speed and ease-of-use of GUIs applications have improved over time, the use of console applications has greatly diminis ...

Disk Utility
A disk utility is a utility software, utility program that allows a user to perform various functions on a computer disk, such as disk partitioning and logical volume management, as well as multiple smaller tasks such as changing drive letters and other mount points, renaming volumes, disk checking, and disk formatting, which are otherwise handled separately by multiple other built-in command (computing), commands. Each operating system (OS) has its own basic disk utility, and there are also separate programs which can recognize and adjust the different filesystems of multiple OSes. Types of disk utilities include disk checkers, disk cleaners and disk space analyzers Disk cleaners Disk cleaners are computer programs that find and delete potentially unnecessary or potentially unwanted files from a computer. The purpose of such deletion may be to free up disk space, to eliminate clutter or to protect privacy. Disk space consuming unnecessary files include temporary files, trash ( ...

System Integrity Protection
System Integrity Protection (SIP, sometimes referred to as rootless) is a security feature of Apple's macOS operating system introduced in OS X El Capitan (2015) (OS X 10.11). It comprises a number of mechanisms that are enforced by the kernel. A centerpiece is the protection of system-owned files and directories against modifications by processes without a specific "entitlement", even when executed by the root user or a user with root privileges (sudo). Apple says that the root user can be a significant risk to the system's security, especially on a system with a single user account on which that user is also the administrator. SIP is enabled by default but can be disabled. Justification Apple says that System Integrity Protection is a necessary step to ensure a high level of security. In one of the WWDC developer sessions, Apple engineer Pierre-Olivier Martel described unrestricted root access as one of the remaining weaknesses of the system, saying that " nypiece of malwa ...

Superuser
In computing, the superuser is a special user account used for system administration. Depending on the operating system (OS), the actual name of this account might be root, administrator, admin or supervisor. In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser .e., uid=0 regardless of the name of that account; and in systems which implement a r model, any user with the role of superuser (or its synonyms) can carry out all actions of the superuser account. The principle of least privilege recommends that most users and applications run under an ordinary account to perform their work, as a superuser account is capable of making unrestricted, potentially adverse, system-wide changes. Unix and Unix-like In Unix-like computer OSes (such as Linux), ''root'' is the conventional name of the user who has all rights or permissions (to all files and programs) in all mod ...

Package Format
Package format is a type of archive containing computer programs and additional metadata needed by package managers; an instance of this type of archive is called a package. While the archive file format itself may be unchanged, package formats carry additional metadata, such as a manifest file or certain directory layouts. Packages may contain either source code or executable files. Packages may be converted from one type to another with software such as Alien. Software supply chain and security Packages are an important component in managing the security and integrity of the software supply chain. Packages containing executables and configuration can be digitally signed to establish the integrity of running software and protect against tampering. Package formats that support code signing include .deb (Debian), .msi (Microsoft Windows), .apk ( Android) and .ipa (IOS, IPadOS).
