Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can. Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. If you know the author, please let me know so I give the attribution. Disclaimer: I'm not the original author of this sheet, but can't recall where I found it.
