Man, am I just insanely lucky? I've never had such trouble with x.0 releases, during the upgrade or after.

FWIW, I've used at least 2 Macs concurrently since '09, and one since '06.

I guess.

I saw that most of the time people did complain about the first releases of the OS. I didn't get most of those problem, though, until Mavericks.

I'm with you. Probably most users are, too. People who aren't experiencing these problems have no need to inhabit threads like these.
