With so many operating systems named after cats, I'm surprised it took this long for mice to be impacted.

I have to unhide my ~/Library folder again

This annoys the **** out of me. I get they want to keep consumers from messing with things but come on.

I used to hate that too, but then I realized you can just hold "option" so that "Library" appears under the "Go" menu in Finder. Now I don't bother unhiding it.

WOW! You are the first person that I know that is having the same issue. I rarely get that, but when I do it is very annoying.
