It's not obvious to me. Apple used to release 1 version of MacOS every 1.5-2.5 years[1]. Now it releases 1 every 11 months. And it's not like the recent versions have some groundbreaking innovations in them. Nobody cares about MacOS upgrades outside of worrying about breakage, or getting a recent enough XCode to target newer iPhones.

"groundbreaking innovation" is mostly "stuff I need" on HN. MacOS has a lot of groundbreaking innovation in it, alone the level of integration with Handoff between different devices is best in class. At the same time, apple is not living in a vacuum like a linux distro, but has to synchronize features between different device classes - it drives an ecosystem, not a macOS distribution.

Speak for yourself. Many people do, for the rest, there is debian stable and RHEL.

> Many people do

Geeks who update everything every 15 minutes and actively follow tech news. Just like there exist people who buy a different set of clothes every season. It seems to me that in the past with the slower release cycle MacOS was more polished and people actually could differentiate between releases. Now most people won’t be even able to tell which one they’re using, and which release is more recent than another.

Last time I checked RHEL is not an LTS version of MacOS.

Last time I checked no one promised and sold an LTS version of macos ever. If you are in a possession of such a contract I suggest to make a claim by apple.
