Catalina

Catalina is a term used as a feminine given name of Spanish origin and as a toponym for places and cultural references. It is a cognate of Catherine and is common in Spanish-speaking communities. Historical and contemporary figures named Catalina reflect the name’s long association with Roman Catholic and Hispanic naming traditions, including Catalina de Aragón, better known in English as Catherine of Aragon.

Catalina Island, commonly called Santa Catalina Island, is an island off the southern coast of California in Los Angeles County. It lies in the Pacific Ocean near the Channel Islands and is known for its rugged terrain, coastal cliffs, and the resort town of Avalon on its northeastern shore. The island covers roughly 76 square kilometers (about 29 square miles) and features marine habitats, hiking trails, and popular tourist activities such as snorkeling, glass-bottom boat tours, and ecotours. Its history includes Indigenous Tongva habitation prior to Spanish exploration, later development for tourism and entertainment, and ownership changes that culminated in conservation efforts to protect its natural landscapes.

MacOS Catalina is the codename for Apple's 2019 desktop operating system, released as macOS 10.15. Named after Santa Catalina Island as part of Apple’s California-themed naming, Catalina introduced notable changes such as the deprecation of iTunes in favor of separate Music, TV, and Podcasts apps, plus the Catalyst project to port iPad apps to macOS. The update emphasized 64‑bit apps only, enhanced security features, and new capabilities like Sidecar for using an iPad as a secondary display.
