The iMac, which had been updated to Big Sur several weeks ago, did not exhibit the issue. I suspected some issue unique to the laptop, so did the usual troubleshooting steps. Then I did a port selfupdate on the iMac and it now had the same problem. I used Time Machine to roll back to before the port selfupdate, and ipython is working correctly again.

It looks like the problem is with py-ptyprocess 0.7.0_0 . The problem goes away if I downgrade to py37-ptyprocess 0.6.0_0 and then rebuild py37-ipython
