Good-bye Catalina, Hello Big Sur

It’s hard to believe that Steve Jobs introduced the first version of OS X on January 5, 2000. At the time, he said that the new operating system would support the Mac for decades, and he wasn’t wrong. With the arrival of the first “cats”, (the first version of OS X was named Cheetah), Apple moved from System 9 to what would become a new era for Apple and the Mac.

Now, twenty years later, macOS 10.15 Catalina marks the end of that era. Apple has finally moved away from an operating system that starts with a 10. Today, Apple released macOS 11.0 Big Sur. With the introduction of new Macs using processors designed by Apple, it seems fitting to introduce an entirely new version of the macOS.

But the new M1 processor and the new macOS 11.0 Big Sur has a long history and we thought it appropriate to take this opportunity to once again, look at the history of OS X and how we got where it is today, and begin the journey tracking macOS version 11.
