Well I mean once it comes out - more for stability improvements than adding features. I'm sure it's going to be a scary beta though.

It sounds like most people’s experience with upgrading file systems is changing from something like FAT32 to NTFS or maybe something like ext3 to reiser or something like that. HFS is b-tree based, and third party tools like DiskWarrior have long been able to rebuild an entirely newly optimized b-tree without reformatting the entire drive. If Apple came up with a new metadata storage format they can build a new b-tree live on disk and swap the root pointer at the end. All of the changes could even be journaled like the existing HFS journaling does. Upgrading a file system sounds more scary than it actually is, since in this case the files themselves are never touched.
Hence why they can be so aggressive with the rollout and why it looks so seamless. The data doesn't move.

Agree. Biggest hurdle right now for upgrading clients from 10.9.5 (yeah, that's right… it is the last "stable" OS without significant issues with productivity apps like Mail and Calendar) to 10.12 is PDFKit, because my business clients rely on PDF and being able to sign/form fill too much. It can't NOT WORK, because many of them are in the legal profession or use PDFs for legal compliance. 10.12 has remedied just about EVERY other issue I had with macOS otherwise… which makes it a shame, then, that I can't push the upgrade.
Oh, come on! I'm not talking about updating soon. Important bugs remain after months of the initial release in the latest MacOS versions.
I don't really have the time for explaining the differences in QC in OS X across all its versions, nor why an OS X update never dissappointed you, nor why there was a time when updating took 5 minutes in CPUs much slower than current ones (and with mechanical HDs).

Isn't it fixed? (I don't know, as I'm still at 10.11.6). I expressed my concern on these forums some months ago and I was told to calm down, that the PDFkit bugs had been fixed already.

Like I said, don't update your important production system if "important bugs" remain.
People's propensity for wanting the newest "features" at the cost of incompatibilities or reliability is what gets them in trouble.
Plenty of OS releases have disappointed me. Not sure what you're reading into my remarks. I was simply pointing out good upgrade practice.
Also, failing you owning a test system, mirroring drives with CCC or the likes, allows you to safely test and revert at the touch of the option-button at boot.
I go back to the Apple II, so save your schooling.
Both El Capitan and MacOS Sierra are still not quite as good as Yosemite. Every time I try to check for updates on both El Capitan and MacOS Sierra I get the spinning beach ball that locks the system for a number of seconds while checking....annoying. Never found this issue with Yosemite....I am still using Yosemite on my main hard drives......

I find both El Capitan and Sierra to be more stable and perform at least as well as Yosemite.
Do you get the spinning beach ball of death when checking for updates on El Capitan and MacOS Sierra?
