No, I haven't installed one. I hadn't realized that Edwin was using it in the past on older versions of MacOS. Apparently, new versions of Mac don't come with an X11 server.
I installed XQuartz, and double-clicking the MIT/GNU Scheme icon in Applications (even after renaming the icon to MIT-Scheme), still doesn't work. However, running MIT/GNU Scheme from an xterm in XQuartz did work, so that's good news. That must be the issue.
