macOS
macOS is a Unix-certified desktop operating system developed by Apple Inc. for Macintosh computers. Introduced as Mac OS X in 2001 following Apple’s 1996 acquisition of NeXT, it combines the hybrid XNU kernel with a graphical user interface and deep integration across Apple’s hardware and services. As of September 2025, the current stable major release is macOS 15 Sequoia (released September 16, 2024), and the next release, macOS 26 Tahoe, was previewed at WWDC on June 9, 2025.
