I understand it's not priority, but in case of latest macOS installer experience is worst since last 4 versions. Too many restarts, progress bars not even reaching 100% before starting from 0 again. ETA in final stage is way off. Most of the time only progress bar is shown, with no message about what is installer doing (but one can clearly see all those restarts in between).
