* Update SC2 setup guide
Removed a sentence that made sense when I included sudo in the command in the previous sentence, but does not make sense otherwise.
* Update en_Super Mario 64.md
It turns out castle has a lowercase l in it.
* Adding SC2 macOS instructions
A few hours ago, I tested whether the client would run successfully on macOS (Send/Receive items, load maps, download maps, etc.). After the successful testing, I thought adding some documentation would be nice for those who want to play Archipelago on a macOS system.
* Don't need sudo
Turns out you don't need sudo to do the download_data, oops.
* Removed Extraneous Parantheses
