Ahhh, there it is!
I woke up Mojave this morning & there was no fog! YAY! I've had my mini for almost 6 1/2 years & I've been having problems for about the last month. Maybe I had a lot of junk files. Maybe they were causing the video problems. That's why I do a clean install.
I'm confused about the difference between hibernate mode 0 & hibernate mode 3. Currently, Mojave is set at hibernate mode 0. There's also a 25. When I woke Mojave this morning, it took maybe 5 seconds for the Desktop to appear. If I understand it correctly, hibernate mode 0 doesn't write RAM's data to the hard drive, but hibernate mode 3 does. One of the hibernate modes powers down the RAM & one keeps the RAM powered. There's a file on the hard drive that stores the contents of the RAM. Where does 25 fit in? I'm confused as to which mode keeps the RAM powered & which one powers down the RAM. Which mode has the fastest power up? My mini is plugged into a UPS so if there's a power failure, I can safely power down my computer.
