Hi,

When I use it on macOS as the below method, I got the error: qt.qpa.xcb: could not connect to display $IP:0

IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
xhost +

docker run --rm -it \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e DISPLAY=$IP:0 \
    -u qtuser \
    jozo/pyqt5 python3 /tmp/hello.py

I solved !

@kaka-lin can you please share your solution? I guess the problem was that XQuartz was not running.

@jozo I used host.docker.internal:0 instead of $IP:0
