Mac App Store in the context of "OS X Lion"

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.

Application software is software that is intended for end-user use – not operating, administering or programming a computer. An application (app, application program, software application) is any program that can be categorized as application software. Application is a subjective classification that is often used to differentiate from system and utility software.

The abbreviation app became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with the release of the Mac App Store in 2010 and the Windows Store in 2011, it began to be used to refer to end-user software in general, regardless of platform.

The Microsoft Store (formerly known as the Windows Store) is a digital distribution platform operated by Microsoft. It was created as an app store for Windows 8 as the primary means of distributing Universal Windows Platform apps. With Windows 10 1803, Microsoft merged its other distribution platforms (Windows Marketplace, Windows Phone Store, Xbox Music, Xbox Video, Xbox Store, and a web storefront also known as "Microsoft Store") into Microsoft Store, making it a unified distribution point for apps, console games, and digital videos. Digital music was included until the end of 2017, and E-books were included until 2019.

As with other similar platforms, such as the Google Play and Mac App Store, Microsoft Store is curated, and apps must be certified for compatibility and content. In addition to the user-facing Microsoft Store client, the store has a developer portal with which developers can interact. Microsoft takes 5–15% of the sale price for apps and 30% on Xbox games. Prior to January 1, 2015, this cut was reduced to 20% after the developer's profits reached $25,000. In 2021, 669,000 apps were available in the store. Categories containing the largest number of apps are "Books and Reference", "Education", "Entertainment", and "Games". The majority of the app developers have one app.

macOS Tahoe (version 26) is the twenty-second and current major release of Apple's macOS operating system. The successor to macOS Sequoia (macOS 15), it was announced at WWDC 2025 on June 9, 2025, and its first developer beta was released the same day. It was released on September 15, 2025.

Tahoe is the final version of macOS that supports Macs with Intel processors; the 2020 iMac, the 2019 16-inch MacBook Pro, the 2020 4-port 13-inch MacBook Pro, and the 2019 Mac Pro models are supported. Future versions will work only on Macs with Apple silicon systems on a chip (SoCs). It is the first version of macOS since Mac OS X Snow Leopard that cannot be upgraded from an older version via the Mac App Store; upgrading it is exclusively available through the System Settings software update preference pane, as is the case with iOS.
