The instructions on https://www.cypress.io/blog/run-cypress-with-a-single-docker-command are slightly different.

Perhaps an independent macOS user could check that the new instructions on https://github.com/BountyHunter1999/cypress-docker-images/blob/patch-1/CONTRIBUTING.md#to-forward-x11-from-inside-a-docker-container-to-a-host-running-macos are correct?

It doesn't look like your instructions set the environment variable IP before you use it. Would you like to double-check? Perhaps I have misunderstood?

xhost +$(ipconfig getifaddr en0)

I just ensured that the value is interpolated in the setting rather than creating a variable outside. You can check that the command is similar.

What about the instruction?

Set up a DISPLAY env var `export DISPLAY="$IP:0"

Where is $IP set?

• Yes, it seems that was missing. I tried not to create the IP variable, it was either that or enter this $(ipconfig getifaddr en0) in multiple places.
  I have added explicit IP assignment now

You have requested my review.

It is a documentation change only and as far as I can see from the text it looks fine.

I would however difficulty approving it, as it contains instructions for a macOS user and I don't have that environment to test on. I don't have any outstanding requests for change however. All my requests for change have been dealt with.
