Why does OSX Version Starts with version 10 ?

[andy8]

Hello,

I would like to know this. Why does OSX releases start with Version 10 ?
When we check the first OSX released in year 2001 (called Cheetah), it was Version 10.0

That progressed to OSX Yosemite with its version being 10.10. My question is why did Apple start referring it as Version 10.0 back in year 2001 ? Any specific reasons behind this ?

Thanks

Because before OS X there was also System 1, 2, 3, 4, 5, 6, 7, 8 and 9?

Because it came after version 9

I wonder whether Apple knew back then that the OS would "stall" at 10, or whether the intention was to proceed to 11 after a couple of years. 10.1 ended up being a minor release so that name made sense, but some of the subsequent releases were huge.

It was preceded by OS9. The 'X' is a bit of superfluous branding fluff, which has landed us with 'OS ten ten point ten' and potentially 'OS ten ten point ten point ten'.

I imagine they at some point tell us they have reimagined the desktop OS as we never had thought it possible, and together with that scrap the less-than-snappy-sounding OS ten ten point ten.

Two reasons: 1) Mac OS X (now called OS X) was the successor to System 9 and "X" is the Roman numeral for the Indian number "10"; and, the "X" also stands for the Unix underpinnings of the operating system.

You realize its OS X where X is the roman number for 10. Prior to this in 2000, Apple had the classic OS, called OS 9, before that OS 8. Prior to that they called it System 7, 6 5 etc.

Basically, its the 10th major incarnation of the OS used to run Macintoshes.
