Posted on: Posted on

macOS (formerly OS X) is the operating system that powers Apple’s Mac computers. It’s known for its user-friendly interface, stability, security, and integration with Apple’s ecosystem of devices and services. Here’s a detailed look, covering its history, features, versions, advantages, disadvantages, and more:

1. History & Evolution

  • Early Days (1984-1997): Apple’s original Macintosh operating system was groundbreaking for its graphical user interface (GUI). However, it faced limitations and struggled to compete with Windows.
  • NeXTSTEP (1987-1996): Apple acquired NeXT in 1997, bringing with it NeXTSTEP, a powerful and advanced operating system. This was the foundation for the modern macOS.
  • OS X (2001): The first version of OS X (Cheetah) was released, based on NeXTSTEP. It introduced a completely new, Unix-based core.
  • OS X to macOS (2012-Present): Apple dropped the “OS X” name and began naming releases after California landmarks (Mavericks, Yosemite, El Capitan, etc.). This signaled a shift towards a more consistent and modern operating system. The current version is macOS Tahoe (26), released in September 2025.
