I terminated after 3 hours of Terminal working on 2.1.1. I then used conda to remove spyder-kernels then ran the install script again and it worked quickly, and Spyder runs now. Sorry for the hassle, hopefully this can help someone else.

I am still curious why I’ve gotten the “need to install 2.1” message multiple times after upgrading Spyder, but for me at least it’s not a pressing need to fix.
