2. A Brief History of macOS

The journey of macOS is marked by innovation and evolution, starting from its early days as Mac OS to its current form.

2.1. Early Versions (Mac OS 1-9)

Introduced in 1984 with the first Macintosh computer, Mac OS was revolutionary for its graphical user interface (GUI). Unlike the command-line interfaces of the time, Mac OS allowed users to interact with the computer using a mouse to click on icons and navigate through folders. The early versions, numbered 1 through 9, focused on ease of use and introduced features like multiple folders.

Mac OS 9, the final version in this series, brought improvements in wireless networking with AirPort support, better USB drivers, and file encryption. It also laid the groundwork for many features that would be included in the next major release.

2.2. Mac OS X (10.0 – 10.8): The Big Cat Era

In March 2001, Apple released Mac OS X, a significant overhaul of the operating system. The “X” in the name represented the number 10. This version marked the beginning of a series of releases named after big cats, starting with Cheetah (10.0). Mac OS X introduced a new GUI called Aqua, known for its translucent design and soft edges.

Subsequent versions in this era included:

10.1 Puma (September 2001): Improved performance and stability.

10.5 Leopard (October 2007): Introduced Time Machine, Apple’s backup application.
10.6 Snow Leopard (August 2009): Focused on improving the performance and efficiency of the OS, and introduced the Mac App Store.
10.7 Lion (July 2011): Integrated features from iOS into the Mac OS.
10.8 Mountain Lion (July 2012): Further aligned Mac and iOS features, enhancing the user experience.

2.3. macOS (10.9 – Present): California Locations

After Mountain Lion, Apple transitioned to naming macOS versions after locations in California. This shift began with Mavericks and continued through subsequent releases.

10.9 Mavericks (October 2013): Marked the start of free upgrades to the OS, adding the Maps and iBooks applications.
10.10 Yosemite (October 2014): Introduced Handoff, enabling users to answer calls and send SMS messages on Macs. The interface was redesigned to resemble iOS 7 more closely.
10.11 El Capitan (September 2015): Offered Apple’s Metal application program interface, with added refinements to the user experience.
