Lion actively screwed up normal people's workflows with the botched "Save As" replacement. I still want an explanation of why they thought that was a good idea. We skipped that one after one of the admin assistants discovered the new joy.
The whole California-series of OS has had a broken Finder. I see some fixes in High Sierra, but its still buggy as heck for large file moves and broken scripting. I'm hoping they take a long hard look at Mac OS like they seem to be with the next iOS. I can forgive removing some UNIX commands, but the general bugs and unexplained crashes are starting to get on my nerves.
I know I sound like an old crank, but I've been a Mac user since 1984. And the last MacOS version that I completely trusted as being loyal to my needs and workflow was Snow Leopard. Every later version has felt like it was really Apple's OS and I was just borrowing it.
It’s certainly no coincidence that the last version of OS X that you could buy with money (be a customer) was Lion, which marked the beginning of a decline.
I would be very happy to see macOS drop back to bi-yearly/loose schedule upgrades. It’s a mature platform that runs on hardware that improves significantly slower than the hardware iOS runs on; at this point insisting on a new release every year rather than when it’s ready is actively detrimental.
As much as I still get excited by new features and tech, I use my Mac exclusively for work, and rock solid reliability is more important to me than new features.
