What Is macOS?
macOS is Apple’s desktop operating system, powering every MacBook, iMac, Mac mini, and Mac Studio. Formerly known as Mac OS X, it was first launched in 2001 and is based on Unix, the same foundation as iOS and iPadOS.
Before macOS, Macs ran Mac OS 9, but the shift to OS X marked the beginning of a modern era for the Mac. Apple has evolved macOS steadily ever since, adding features like Time Machine, iCloud integration, and now cross-platform apps powered by Apple silicon.

- At the top of the window, you’ll see the macOS name (like Sonoma or Sequoia) and version number (like 14.7 or 15.5)
That’s it. Now you’ll know exactly where your system stands and whether it’s time for an update.
Which macOS Versions Are Still Supported?
Apple generally supports the three most recent versions of macOS with security updates:
