When starting the client server on macOS use GC_DONT_GC=1 npm run start.

That is, include GC_DONT_GC=1 in front of the command npm run start.

Then, open a browser tab to http://localhost:8009/ and, using Brave Browser, Advance from warnings. (Not https, see note below).

Note: I had to update my Plutus-apps/plutus-playground-client/webpack.config.js file per prodineeritecht's recommendation to bi-pass the https proxy firewall.
