+# To run a Docker container on Mac with display support, you need to use XQuartz, a free and open-source software that provides an X11 window system for macOS.
+# Here are the steps you need to follow:
+# Install XQuartz: Download and install XQuartz from the official website (https://www.xquartz.org/).
+# Enable XQuartz: Open XQuartz and go to XQuartz > Preferences > Security. Make sure that the “Allow connections from network clients” option is checked.
+# Install socat: Install socat using Homebrew. Run the following command in the Terminal:
+brew install socat
+# Run socat: Run socat in the Terminal to forward X11 connections from the Docker container to XQuartz. Run the following command:
+socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
+# To check the tcp ports that are listenning
+sudo lsof -i -P | grep LISTEN | grep :$PORT
+# Start the Docker container: Start the Docker container with the following command:
+docker run -e DISPLAY=host.docker.internal:0 <image-name>
+# Replace <image-name> with the name of the Docker image you want to run.
+# Test the display support: Test the display support by running a graphical application inside the Docker container. For example, you can run xclock or xeyes.
+# e.g:
+docker run -it --rm -e DISPLAY=host.docker.internal:0 $DOCKER_IMAGE bash
+python -m pip install --upgrade pip
+apt update && apt install x11-apps
+xclock
+xeyes
