Answer 1

I did something similar to what Sam did and was able to make it work.

I simply made a copy of the libmysqlclient.21.dylib file located in my up-to-date installation of MySQL 8.0.13 which is was in /usr/local/mysql/lib and moved that copy under the same name to /usr/lib.

You will need to temporarily disable security integrity protection on your mac however to do this since you won't have or be able to change permissions to anything in /usr/lib without disabling it. You can do this by booting up into the recovery system, click Utilities on the menu at the top, and open up the terminal and enter csrutil disable into the terminal. Just remember to turn security integrity protection back on when you're done doing this! The only difference from the above process will be that you run csrutil enable instead.
