Macintosh MapleLegends Won't Run (osSierra)

I am running macOS Sierra and I'm having trouble getting MapleLegends to load. It said there was an X11 error, and it "failed to activate core devices." I looked around on the forums and there is an older post similar to my issue and the solution was an updated wrapper. I tried to update the wrapper myself but I couldn't get it to work. Can someone give me a step-by-step for updating the wrapper or link a copy that will work on my computer? Thanks for the help!

Edit: To people suffering from similar problems. I also encountered a "read-only file volume" issue as well and the steps I took to fix (even partially) these problems are in a comment of mine below along with error codes. I don't want to be that "nevermind, fixed" guy...
