I'm on a Mac running Big Sur with the intel chip. I've followed all the steps to set up the local Plutus environment as suggested by Lars in the Plutus Pioneer 3rd iteration.

However, when I navigate to localhost in the browser it says that 'This page isn't working. Localhost didn't send any data.' I've tried accessing the app on Brave and Safari with no luck. No additional info is presented in the terminal. Any ideas?
