Like We shared it earlier todayMacOS – formerly known as Mac OS X – will be 20 years old on Wednesday, March 24, 2021. To mark the occasion, Scott Forstall decided to use his Twitter account tonight to congratulate Mac OS X.
In a post on his personal Twitter account, which he does not use often, Forstall is celebrating the 20th anniversary of Mac OS X and remembers when Steve Jobs decided to name the tenth version of Apple’s operating system.
“I still remember when we called you. In a small room at IL1. When Steve cut a big X on the wall and smiled. Look how far I got from Little Cheetah” said Forrestal. The system was named Mac OS at the time, but Apple was working on an entirely new version that became Mac OS X.
Old Mac users might remember that the first versions of Mac OS X were named after the big cats, but that’s only because Apple used “Cheetah” as the codename for Mac OS X 10.0. After that, the company decided to use the big cat names for other versions of OS X, such as Puma, Tiger and Leopard.
Scott Forrestle has worked for NeXT with Steve Jobs since 1992 and joined Apple in 1997 after the company was acquired. He became senior vice president of software at Apple in 2003 and was deeply involved in iPhone development in 2005 – making Forstall considered the “father of iOS”. In 2006, he took the lead in developing Mac OS X as well.
Forstall left Apple in 2012 after an Apple Maps controversy as the company replaced Google Maps with its own map solution, which was deemed incomplete and buggy. It was mainly replaced by Craig Federighi, who leads Apple’s software engineering to this day.
