This is an incomplete list of the various technologies (and core applications) in macOS.
macOS is a series of graphical operating systems developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac family of computers. Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS, after Microsoft Windows.

The Apple Filing Protocol (AFP), formerly AppleTalk Filing Protocol, is a proprietary network protocol, and part of the Apple File Service (AFS), that offers file services for macOS and the classic Mac OS. In macOS, AFP is one of several file services supported, with others including Server Message Block (SMB), Network File System (NFS), File Transfer Protocol (FTP), and WebDAV. AFP currently supports Unicode file names, POSIX and access control list permissions, resource forks, named extended attributes, and advanced file locking. In Mac OS 9 and earlier, AFP was the primary protocol for file services.
Apple File System (APFS) is a proprietary file system for macOS High Sierra (10.13) and later, iOS 10.3 and later, tvOS 10.2 and later, and watchOS 3.2 and later, developed and deployed by Apple Inc. It aims to fix core problems of HFS+, APFS's predecessor on these operating systems. Apple File System is optimized for flash and solid-state drive storage, with a primary focus on encryption.
AppleScript is a scripting language created by Apple Inc. that facilitates automated control over scriptable Mac applications. First introduced in System 7, it is currently included in all versions of macOS as part of a package of system automation tools. The term "AppleScript" may refer to the language itself, to an individual script written in the language, or, informally, to the macOS Open Scripting Architecture that underlies the language.
In NeXTSTEP, OPENSTEP, GNUstep, and their lineal descendants macOS and iOS, a bundle is a file directory with a defined structure and file extension, allowing related files to be grouped together as a conceptually single item.
Carbon is one of Apple’s C-based application programming interfaces (APIs) for Mac OS X, the operating system that powers Macintosh computers. Carbon provided a good degree of backward compatibility for programs that ran on Mac OS 8 and 9. Developers could use the Carbon APIs to port their “classic” Mac software to the Mac OS X platform with little effort, compared to porting the app to the entirely different Cocoa system, which originated in OPENSTEP.
Cocoa is Apple's native object-oriented application programming interface (API) for its desktop operating system macOS.

iCloud is a cloud storage and cloud computing service from Apple Inc. launched on October 12, 2011. As of February 2016, the service had 782 million users.
Image Capture is an application program from Apple that enables users to upload pictures from digital cameras or scanners which are either connected directly to the computer or the network. It provides no organizational tools like iPhoto but is useful for collating pictures from a variety of sources with no need for drivers.
Inkwell, or simply Ink, is the name of the handwriting recognition technology developed by Apple Inc. and built into the Mac OS X operating system. Introduced in an update to Mac OS X v10.2 "Jaguar", Inkwell can translate English, French, and German writing. The technology made its debut as "Rosetta", an integral feature of Apple Newton OS, the operating system of the short-lived Apple Newton personal digital assistant. Inkwell's inclusion in Mac OS X led many to believe Apple would be using this technology in a new PDA or other portable tablet computer. However, none of the touchscreen iOS devices – iPhone/iPod/iPad – offers Inkwell handwriting recognition.
