This year we were introduced to the macOS Mojave (name of a desert in the state of California). After so many years and several codenames have passed, at the very least curious to think of all of them (internal nomenclatures, which are not publicly disclosed) that the versions of the operating systems of Ma’s computers have received over the years. And we decided to compile all this to kill the curiosity of others. ?
Starting with the Macintosh, Apple’s first operating systems based on a graphical interface were System 6 (released in 1988) and System 7 (also known as Mac OS 7, 1991). Contrary to what we follow today, systems at that time were given different names and did not follow a pattern:
- System 6.04: Antares
- System 6.05: Big Deal
- System 6.06: SixPack
- System 6.08: Terminator
- System 7: Blue
- System 7.01: Road Warrior (used in early PowerBooks), Beta Cheese
- System 7.1: Cube-E, I Tripoli
- System 7.1 Pro: Jirocho
- System 7.5: Mozart and then Capone (Apple expected that, with the name of the gngster ?Capone?, it would dominate the popularity of the code name for Windows 95, which was ?Chicago?)
- System 7.5, first version: Danook
- System 7.5, second version: Thag
- System 7.52: Marconi
- System 7.53: Unity
- System 7.53, first version: Buster
- System 7.53, second version: Son of Buster
- Mac OS 7.6: Harmony
- Mac OS 7.61: Ides of Buster
In 1997, Apple released the biggest update to its operating system so far: Mac OS 8. Versions of that operating system were also named without a defined string or connection:
- Mac OS 8: Time
- Mac OS 8.1: Bride of Buster
- Mac OS 8.5: Allegro
- Mac OS 8.6: Veronica
- Mac OS 8.7: Sonata
From 2001 to 2012, the internal versions of OS X were named after big cats, like the famous Snow Leopard and Lion. As Apple marketing was also using these names to publicly promote software, the team decided, starting with OS X 10.3, to change the codenames used internally to wine names while the feline names continued to be used for public versions.
Although the external code names of OS X changed to the California regions in 2013, the internal ones remained based on wine names until 2014. In 2015, with version 10.11, the development team changed the code nomenclature back to types but of.
In 2016, OS X officially became macOS and Apple continued to use California locations as external codenames and mas types as internal.
Check below the public and internally used codenames of all versions (including a beta) of OS X / macOS already released:
- OS X 10 beta: Kodiak
- OS X 10.0: Cheetah
- OS X 10.1: Puma
- OS X 10.2: Jaguar
- OS X 10.3: Panther (internal: Pinot)
- OS X 10.4: Tiger (internal: Merlot)
- OS X 10.4.4: Tiger (internal: Chardonay)
- OS X 10.5: Leopard (internal: Chablis)
- OS X 10.6: Snow Leopard
- OS X 10.7: Lion (internal: Barolo)
- OS X 10.8: Mountain lion (internal: Zinfandel)
- OS X 10.9: Mavericks (internal: Cabernet)
- OS X 10.10: Yosemite (internal: Syrah)
- OS X 10.11: El Capitan (internal: Gala)
- macOS 10.12: Sierra (internal: Fuji)
- macOS 10.13: High Sierra (internal: Wolf)
- macOS 10.14: Mojave (internal: Liberty)
Not only is macOS codenamed for its internal and public versions; iOS also has names for all versions developed over the years.
Interesting, isn’t it? ?
