If you’re a proud owner of a Mac, then you’re probably familiar with macOS, the operating system that powers your Apple computer. What you might not know is that macOS has a rich and fascinating history, with each major version bringing new features, improvements, and sometimes even a few headaches. So, let’s take a trip down memory lane and dive into the evolution of macOS with a timeline of its major versions.
Mac OS X 10.0 Cheetah (2001)
The year was 2001, and Apple was ready to make a splash in the operating system world with the release of Mac OS X 10.0, codenamed Cheetah. This was the first version of the OS to carry the now-familiar “X” in its name, which signified its Unix-based architecture. While Cheetah was certainly a leap forward in terms of stability and performance compared to its predecessor, Mac OS 9, it was a bit rough around the edges and lacked some of the features that we now take for granted.
Mac OS X 10.1 Puma (2001)
Hot on the heels of Cheetah came Puma, which addressed many of the issues that plagued the initial release. Puma also introduced the much-anticipated Aqua interface, a fresh and colorful design that gave macOS its distinctive look. Apple also added a slew of new features, such as DVD playback support, enhanced performance, and better compatibility with third-party software. With Puma, macOS started to resemble the polished and refined operating system that we know today.
Mac OS X 10.2 Jaguar (2002)
Jaguar roared onto the scene in 2002, bringing with it a host of new features that further solidified macOS as a viable alternative to Windows.

Mac OS X 10.3 Panther (2003)

And who could forget the iconic Stacks feature, which tidied up our cluttered desktops with a click? Leopard’s impact on macOS was undeniable.

Mountain Lion also brought us Notification Center, a centralized hub for alerts and notifications, and Gatekeeper, a security feature that helped protect us from malicious software.
OS X 10.9 Mavericks (2013)
Mavericks was a breath of fresh air for macOS, shaking things up with a renewed focus on performance and efficiency.
