Apple Maps is a web mapping service developed by Apple. As the default map system of iOS, iPadOS, macOS, tvOS, visionOS, and watchOS, it provides directions and estimated times of arrival for driving, walking, cycling, and public transportation navigation. A "Flyover" mode shows certain urban centers and other places of interest in a 3D landscape composed of models of buildings and structures.

First released in 2012, Apple Maps replaced Google Maps as the default map system on Apple devices. At launch, it drew criticism from users and reviewers for incorrect directions, sparse data about public transportation, and various other bugs and errors. Apple has since further developed the software to address the issues raised by such criticism.

Krita (/ˈkriːtə/ KREE-tə) is a free and open-source raster graphics editor designed primarily for digital art and 2D animation. Originally created for Linux, the software also runs on Windows, macOS, Haiku, Android, and ChromeOS, and features an OpenGL-accelerated canvas, colour management support, an advanced brush engine, non-destructive layers and masks, group-based layer management, vector artwork support, and switchable customisation profiles.

The software is also available as paid software, distributed on Microsoft Store, Steam, Epic Games Store, and Mac App Store. Payments support the development of the software. The paid version has automatic updates.

Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, macOS, Linux, BSD, Haiku, and IRIX. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating models for video games.

Blender was used to produce the Academy Award-winning film Flow (2024).

Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Versions were later released for Linux, macOS, iOS, iPadOS, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, on which it serves as the platform for web applications.

Most of Chrome's source code comes from Google's free and open-source software project known as Chromium, but Chrome is licensed as proprietary freeware. WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine; all Chrome variants except iOS used Blink as of 2017.

Safari is a web browser developed by Apple. It is built into several of Apple's operating systems, including macOS, iOS, iPadOS, and visionOS, and uses Apple's open-source browser engine WebKit, which was derived from KHTML.

Safari was introduced in an update to Mac OS X Jaguar in January 2003, and made the default web browser with the release of Mac OS X Panther that same year. It has been included with the iPhone since the first-generation iPhone in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support for Apple Pay, and authentication with FIDO2 security keys. Its user interface was redesigned in Safari 15, Safari 18, and Safari 26.

Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 or later versions of Windows, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, and other operating systems, such as ReactOS. It is the default, pre-installed browser on Debian, Ubuntu, and other Linux distros. Firefox is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version was also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser, until April 30, 2021, when Firefox would be discontinued on that platform. Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998, before its acquisition by AOL. Firefox was created in 2002 under the codename "Phoenix" by members of the Mozilla community who desired a standalone browser rather than the Mozilla Application Suite bundle. During its beta phase, it proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet Explorer 6. It was released on November 9, 2004, and challenged Internet Explorer's dominance with 60 million downloads within nine months. In November 2017, Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface.

Firefox usage share grew to a peak of 32.21% in November 2009, with Firefox 3.5 overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole; its usage then declined in competition with Google Chrome. As of February 2025, according to StatCounter, it had a 6.36% usage share on traditional PCs (i.e. as a desktop browser), making it the fourth-most popular PC web browser after Google Chrome (65%), Microsoft Edge (14%), and Safari (8.65%).

A screen reader is a form of assistive technology (AT) that renders text and image content as speech or braille output. Screen readers are essential to blind people, and are also useful to people who are visually impaired, illiterate or learning-disabled. Screen readers are software applications that attempt to convey what people with normal eyesight see on a display to their users via non-visual means, like text-to-speech, sound icons, or a braille device. They do this by applying a wide variety of techniques that include, for example, interacting with dedicated accessibility APIs, using various operating system features (like inter-process communication and querying user interface properties), and employing hooking techniques.

Microsoft Windows operating systems have included the Microsoft Narrator screen reader since Windows 2000, though separate products such as Freedom Scientific's commercially available JAWS screen reader and ZoomText screen magnifier and the free and open source screen reader NVDA by NV Access are more popular for that operating system. Apple Inc.'s macOS, iOS, and tvOS include VoiceOver as a built-in screen reader, while Google's Android provides the Talkback screen reader and its ChromeOS can use ChromeVox. Similarly, Android-based devices from Amazon provide the VoiceView screen reader. There are also free and open source screen readers for Linux and Unix-like systems, such as Speakup and Orca.

Flyover is a feature on Apple Maps that allows users to view select areas in a 3D setting. Flyover also allows users to take "tours" of these locations through the City Tours feature, showcasing various landmarks in the area. Imagery is provided through the use of planes, which collect fine data on buildings. Flyover is available on all Apple devices which also support Maps, including iOS and macOS.

Initially founded in 2012, along with Apple Maps itself, Flyover has expanded from its initial 10 locations in the US and Europe to now include over 300 cities, landmarks, and parks across all six inhabited continents through a series of multiple expansions, notably in 2014, 2019 and 2024. Upon release, Flyover was criticized for various visual issues, as part of a larger criticism of the overall release of Apple Maps, however, Flyover has also been praised for its detail and uniqueness.

Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS. It was created in 1987 by Thomas and John Knoll. It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become genericised as a verb (e.g., to "photoshop" an image, "photoshopping", and "photoshop contest") although Adobe disapproves of such use.

Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed independently of Photoshop that run inside it and offer new or enhanced features.

Mac is a brand of personal computers designed and marketed by Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to the McIntosh apple. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOS operating system, which is not licensed to other manufacturers and exclusively bundled with Mac computers. This operating system replaced Apple's original Macintosh operating system, which has variously been named System, Mac OS, and Classic Mac OS.

Jef Raskin conceived the Macintosh project in 1979, which was usurped and redefined by Apple co-founder Steve Jobs in 1981. The original Macintosh was launched in January 1984 at US$2,495 (equivalent to $7,600 in 2024), after Apple's "1984" advertisement during Super Bowl XVIII. A series of incrementally improved models followed, sharing the same integrated case design. In 1987, the Macintosh II brought color graphics, but priced as a professional workstation and not a personal computer. Beginning in 1994 with the Power Macintosh, the Mac transitioned from Motorola 68000 series processors to PowerPC. Macintosh clones by other manufacturers were also briefly sold afterwards. The line was refreshed in 1998 with the launch of the iMac G3, reinvigorating the line's competitiveness against commodity IBM PC compatibles. Macs transitioned to Intel x86 processors by 2006 along with new sub-product lines MacBook and Mac Pro. Since 2020, Macs have transitioned to Apple silicon chips based on ARM64.

Steam is a digital distribution service and storefront developed by Valve. It was launched as a software client in September 2003 to provide video game updates automatically for Valve's games and expanded to distributing third-party titles in late 2005. Steam offers various features, such as game server matchmaking with Valve Anti-Cheat (VAC) measures, social networking, and game streaming services. The Steam client functions include update maintenance, cloud storage, and community features such as direct messaging, an in-game overlay, discussion forums, and a virtual collectable marketplace. The storefront also offers productivity software, game soundtracks, videos, and sells hardware made by Valve, such as the Valve Index and the Steam Deck.

Steamworks, an application programming interface (API) released in 2008, is used by developers to integrate Steam's functions, including digital rights management (DRM), into their products. Several game publishers began distributing their products on Steam that year. Initially developed for Windows, Steam was ported to macOS and Linux in 2010 and 2013 respectively, while a mobile version of Steam for interacting with the service's online features was released on iOS and Android in 2012.

The Epic Games Store is a video game digital distribution service and storefront operated by Epic Games. It launched in December 2018 as a software client, for Microsoft Windows and macOS, and online storefront. Android and iOS versions of the store launched in August 2024, with the iOS version only available for European users. The service provides friends list management, game matchmaking, and other features. Epic Games has further plans to expand the feature set of the storefront but it does not plan to add as many features as other digital distribution platforms, such as discussion boards or user reviews, instead using existing social media platforms to support these.

Epic began offering digital distribution for game publishers after the success of Fortnite, released in 2017, which Epic distributed using their own software channels to players on Windows and macOS systems. Tim Sweeney, founder and CEO of Epic Games, stated in August 2017 that the revenue cut of Steam, the dominant game storefront from Valve, was unreasonably high at 30%, and suggested that they could run a profitable store with as little as an 8% cut. By launch, Epic Games had settled on a 12% revenue cut for titles published through the store, as well as dropping the licensing fees for games built on their Unreal Engine, normally 5% of the revenue.

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.

DaVinci Resolve is a proprietary application for non-linear video editing, color correction, color grading, visual effects, and audio post-production. It is developed by the Australian company Blackmagic Design for macOS, Windows, iPadOS and Linux. The software was originally created by the American company da Vinci Systems and released as da Vinci Resolve. In 2009, da Vinci Systems was acquired by Blackmagic Design, which has since continued the software's development.

DaVinci Resolve is available in two editions: a free version, and a paid version known as DaVinci Resolve Studio. The Studio edition includes support for resolutions beyond 4K (up to 32K) and frame rates up to 120 frames per second, as well as 10-bit video processing, multiple GPU acceleration, stereoscopic 3D, HDR grading, collaborative workflows, additional plug-ins and AI-driven features.

A color picker (also color chooser or color tool) is a graphical user interface widget, usually found within graphics software or online, used to select colors and, in some cases, to create color schemes (the color picker might be more sophisticated than the palette included with the program). Operating systems such as Microsoft Windows or macOS have a system color picker, which can be used by third-party programs (e.g., Adobe Photoshop).

MythTV is a free and open-source digital video recorder and media center application with a simplified "10-foot user interface" design for the living room TV. It turns a computer with the necessary hardware into a network streaming digital video recorder, a digital multimedia home entertainment system, or home theater personal computer. It can be considered a free and open-source alternative to TiVo or Windows Media Center. It runs on various operating systems, primarily Linux, macOS, and FreeBSD.

Rocket League is a 2015 vehicular soccer video game developed and published by Psyonix. A sequel to 2008's Supersonic Acrobatic Rocket-Powered Battle-Cars, Rocket League features up to eight players assigned to each of the two teams, using "rocket-powered" vehicles to hit a ball into their opponent's goal and score points over the course of a match. The game includes single-player and multiplayer modes that can be played both locally and online, including cross-platform play between all versions.

Psyonix began formal development of Rocket League around 2013, refining the gameplay from Battle-Cars to address criticism and fan input. Psyonix also recognized their lack of marketing from Battle-Cars and engaged in both social media and promotions to market the game. Rocket League was first released on the PlayStation 4 and Windows respectively in July 2015, with ports for Xbox One and Nintendo Switch being released later on. Physical retail versions for PlayStation 4 and Xbox One were distributed starting in 2016 by 505 Games and later by Warner Bros. Interactive Entertainment. Versions for macOS and Linux were also released in 2016, but support for their online services was dropped in 2020. Rocket League is developed under the games as a service model; later updates for the game enabled the ability to modify core rules and added new game modes, including ones based on ice hockey, gridiron football and basketball. It has been offered as free-to-play since 2020 when Epic Games acquired Psyonix.

World of Warcraft (WoW) is a 2004 massively multiplayer online role-playing (MMORPG) video game developed and published by Blizzard Entertainment for Windows and macOS. Set in the Warcraft fantasy universe, World of Warcraft takes place within the fictional planet Azeroth, approximately four years after the events of the previous game in the series, Warcraft III: The Frozen Throne. The game was announced in 2001, and was released for the 10th anniversary of the Warcraft franchise on November 23, 2004. Since launch, World of Warcraft has had ten major expansion packs: The Burning Crusade (2007), Wrath of the Lich King (2008), Cataclysm (2010), Mists of Pandaria (2012), Warlords of Draenor (2014), Legion (2016), Battle for Azeroth (2018), Shadowlands (2020), Dragonflight (2022), and The War Within (2024). Two further expansions, Midnight and The Last Titan, were announced in 2023.

Inspired by other MMORPGs, particularly EverQuest, World of Warcraft allows players to create a character avatar and explore an open game world in third- or first-person view, exploring the landscape, fighting various monsters, completing quests, and interacting with non-player characters (NPCs) or other players. The game encourages players to work together to complete quests, enter dungeons and engage in player versus player (PvP) combat, however, the game can also be played solo without interacting with others. The game primarily focuses on character progression, in which players earn experience points to level up their character to make them more powerful, obtain better equipment by defeating monsters and completing challenges, and buy and sell items using in-game currency, among other game systems.
