downgrade from mojave to high sierra
Not really happy with Mojave 10.14.6 and like to go back to High Sierra. So far it seems not possibe, though I have made a copy with time machine before starting the upgrade. Up till now time machine not used on Mojave. Most important reason, OS start up very2x slow, it takes 2 min. and 45 sec. where as High Sierra only less than one min.
