System Information For Mac
Your Mac includes a very useful built-in app, called System Information, that allows you to view a summary of information about your computer. This app is a system profiler included with macOS that displays hardware, network, drivers, and software information about your system. This short article teaches you how to open and use the System Information app on your Mac. This information can be viewed, saved, printed or sent to Apple.
System Information (formerly System Profiler) in OS X provides a detailed breakdown of the hardware and software configuration of a Mac, from Bluetooth information and attached USB devices to installed software and extensions.
The ability to generate system reports via the command-line using system_profiler provides a level of flexibility that System Information cannot, such as generating or scheduling reports on remote Macs via SSH. This can be advantageous when trying to determine what software is installed on which Mac or if any users are running an outdated version of OS X.
Most Mac users likely use the About This Mac feature and System Information app to get system information about a Mac, and while there is nothing wrong with that approach, some users may find it helpful to get comprehensive system information about a Mac through the command line by using Terminal. The Terminal has several advantages, ranging from remote access, to accessibility even if the GUI is misbehaving, to producing easily scannable output in text format.

If interested, you can also get system information including macOS version and kernel information using sw_vers and uname, or see everything paging through system_profiler output. You can also grab cpu info with sysctl from the command line if you only want information pertaining to the processor.
macOS (/ˌmækoʊˈɛs/;[5] previously OS X and originally Mac OS X) is a Unix operating system[6] 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[7] and after are UNIX 03 certified,[8] with an exception for OS X 10.7 Lion.[9] Apple's other operating systems (iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS.
A prominent part of macOS's original brand identity was the use of Roman numeral X, pronounced "ten" as in Mac OS X and also the iPhone X, as well as code naming each release after species of big cats, or places within California.[10] Apple shortened the name to "OS X" in 2011 and then changed it to "macOS" in 2016 to align with the branding of Apple's other operating systems, iOS, watchOS, and tvOS. After sixteen distinct versions of macOS 10, macOS Big Sur was presented as version 11 in 2020, macOS Monterey was presented as version 12 in 2021, and macOS Ventura was presented as version 13 in 2022.
The heritage of what would become macOS had originated at NeXT, a company founded by Steve Jobs following his departure from Apple in 1985. There, the Unix-like NeXTSTEP operating system was developed, before being launched in 1989. The kernel of NeXTSTEP is based upon the Mach kernel, which was originally developed at Carnegie Mellon University, with additional kernel layers and low-level user space code derived from parts of BSD.[11] Its graphical user interface was built on top of an object-oriented GUI toolkit using the Objective-C programming language.
Throughout the early 1990s, Apple had tried to create a "next-generation" OS to succeed its classic Mac OS through the Taligent, Copland and Gershwin projects, but all were eventually abandoned.[12] This led Apple to purchase NeXT in 1996, allowing NeXTSTEP, then called OPENSTEP, to serve as the basis for Apple's next generation operating system.[13]This purchase also led to Steve Jobs returning to Apple as an interim, and then the permanent CEO, shepherding the transformation of the programmer-friendly OPENSTEP into a system that would be adopted by Apple's primary market of home users and creative professionals. The project was first code named "Rhapsody" and then officially named Mac OS X.[14][15]
Mac OS X was originally presented as the tenth major version of Apple's operating system for Macintosh computers; until 2020, versions of macOS retained the major version number "10". The letter "X" in Mac OS X's name refers to the number 10, a Roman numeral, and Apple has stated that it should be pronounced "ten" in this context. However, it is also commonly pronounced like the letter "X".[16][17] Previous Macintosh operating systems (versions of the classic Mac OS) were named using Arabic numerals, as with Mac OS 8 and Mac OS 9.[18][16] As of 2020 and 2021, Apple reverted to Arabic numeral versioning for successive releases, macOS 11 Big Sur and macOS 12 Monterey, as they have done for the iPhone 11 and iPhone 12 following the iPhone X.
The first version of Mac OS X, Mac OS X Server 1.0, was a transitional product, featuring an interface resembling the classic Mac OS, though it was not compatible with software designed for the older system. Consumer releases of Mac OS X included more backward compatibility. Mac OS applications could be rewritten to run natively via the Carbon API; many could also be run directly through the Classic Environment with a reduction in performance.
Apple rapidly developed several new releases of Mac OS X.[23] Siracusa's review of version 10.3, Panther, noted "It's strange to have gone from years of uncertainty and vaporware to a steady annual supply of major new operating system releases."[24] Version 10.4, Tiger, reportedly shocked executives at Microsoft by offering a number of features, such as fast file searching and improved graphics processing, that Microsoft had spent several years struggling to add to Windows with acceptable performance.[25]
As the operating system evolved, it moved away from the classic Mac OS, with applications being added and removed.[26] Considering music to be a key market, Apple developed the iPod music player and music software for the Mac, including iTunes and GarageBand.[27] Targeting the consumer and media markets, Apple emphasized its new "digital lifestyle" applications such as the iLife suite, integrated home entertainment through the Front Row media center and the Safari web browser. With increasing popularity of the internet, Apple offered additional online services, including the .Mac, MobileMe and most recently iCloud products. It later began selling third-party applications through the Mac App Store.
A key development for the system was the announcement and release of the iPhone from 2007 onwards. While Apple's previous iPod media players used a minimal operating system, the iPhone used an operating system based on Mac OS X, which would later be called "iPhone OS" and then iOS. The simultaneous release of two operating systems based on the same frameworks placed tension on Apple, which cited the iPhone as forcing it to delay Mac OS X 10.5 Leopard.[32] However, after Apple opened the iPhone to third-party developers its commercial success drew attention to Mac OS X, with many iPhone software developers showing interest in Mac development.[33]
In 2012, with the release of OS X 10.8 Mountain Lion, the name of the system was officially shortened from Mac OS X to OS X, after the previous version shortened the system name in a similar fashion a year prior. That year, Apple removed the head of OS X development, Scott Forstall, and design was changed towards a more minimal direction.[39] Apple's new user interface design, using deep color saturation, text-only buttons and a minimal, 'flat' interface, was debuted with iOS 7 in 2013. With OS X engineers reportedly working on iOS 7, the version released in 2013, OS X 10.9 Mavericks, was something of a transitional release, with some of the skeuomorphic design removed, while most of the general interface of Mavericks remained unchanged.[40] The next version, OS X 10.10 Yosemite, adopted a design similar to iOS 7 but with greater complexity suitable for an interface controlled with a mouse.[41] 2ff7e9595c
