What have they done? I installed Mojave, OMG! My mac is screwed. I'm not exaggerating here. Many apps no longer work or even start up. I get the beach ball with almost every click of the mouse. I here on my PC because my mini is hopelessly slow using the net either with chrome or safari. Safari which I don't use much anyway keeps crashing. DVD's don't play anymore on my superdrive. The cursor stops, crawls, and jitters all over the screen, it's that bad. I don't use time machine so I cant roll back. My OS is on an SSD so it's usually faster than most. How do I get out of this?
