Well, my opinion for this OS is far from OK, in fact I can't use the word for it on here. Whoever devised this needs to go back to school. Here are a few reasons ( & just a few): 1. Blocked email sender....I can block these & they just keep coming back. 2. Recovered email: This is the biggest bunch of junk I have seen. You can delete trash and there are on the recovered crap. Delete those & some are back on trash/junk. Spend a few hours a day trying to get these thing off & most block but that's a joke. 3. Delete the recovered folder(s) & shortly they are back again. Read somewhere they were on Mojave but I never had any of this junk. 4. Catalina doesn't upgrade. Still at 10.15 even though I've seen posts that are on beta 3 & 4. Those are just a few things that I know most of you tech guys laugh at or seem trivial but not to me. If you know how to fix this junk OS, let me know.
