Right… so Apple should test their OS on EVERY variation of hardware configuration created by people using the dozens of 3rd-party SSDs on the market?
Apple open up their OS every year for the public to beta test… and there were plenty of versions before the release, enough for major bugs to be found. But the number of early adoptees of a new macOS at release far outnumbers the people on public/dev beta tests, so there are going to be issues discovered after release.
IMHO, most people should hold off until .2 of a release if they don’t really need the new features.
The common factor with the 3 Macs in my household that have had no major problems with High Sierra is that they all have Apple-installed SSDs…
