From time to time there are comments on the forums about the maturity of macOS. Surely on June 4 at WWDC Apple will present macOS 10.14, extending this operating system at least another year. Leaving the debates aside for the moment, we can establish that macOS is Apple's longest-running operating system, outperforming OS X, which we know as Classic Mac OS.
The first version of Mac OS X came out in 2001Therefore, we can establish that Apple's operating system, at least its foundations, have been on the market for more than 17 years.
We know the information from the hand of Jason Snell who recently posted:
Today it is 17 years, one month and 29 days since Mac OS X 10.0 was released. March 24, 2001. It's an oddly strange number: 6.269 days, but it's also the exact time between January 24, 1984 (the original Macintosh release) and March 24, 2001.
In other words, today the second era of the Mac operating system, with Mac OS X (now macOS) has been around as long as the first era.
However, the blogger points out, because we can take into account the betas of the operating systems or not.
There was a public beta version of Mac OS X. The Mac OS 9 "funeral" didn't take place until 2002. Classic Mode continued to work within Mac OS X until it was removed in Mac OS X 10.5 Leopard.
Apple has been something special since its inception. A proof of this is shown in that the first versions of its operating system had no name, they only referred to the ROM number and the system folder. The first operating system name that we know of was called System 5, It was 1987. Without much originality, Apple changed the name in 1996 to the operating system, which was called System 7.6.
We agree with Snell himself, in relation to not see a change in strategy in the short term, even more so when Apple is reprogramming the system completely with the arrival of APFS. The first action occurred in macOS High Sierra and the second will be in the new version that we will see at WWDC 2018.
