Are all of these failures of El Capitan normal for a new OS X?
I'm kinda new to Macs/Apple, so this is the first time I've encountered a new operating system installation. That's a lot of problems. Gotta say, it kinda scares me. My installation went completely smooth, except for the first start-up but it wasn't that bad and I figure it's just familiarity with the "Apple way". I don't fiddle with unusual apps much (which seems to be causing a lot of headaches) and would probably concentrate on Apple-supported apps, anyways, for the sake of safety. As my machine gets older (I think my last windows machine was 15-20 years old when I converted), I'll probably be more careful to check requirements on a new installation and make darn sure I can revert back to the previous version, if it breaks.
Mac mini, OS X El Capitan (10.11)
