Thank you for the clarification. I wasn’t sure why you expected a pop-up, but this means the issue is not that you don’T see a pop-up, but that the Docker Desktop GUI does not show up. Check this post please
It helped the user in that topic. Don’t forget to execute the last two lines of the script. And reboot MacOS again if needed after that. These were the solutions in all cases I have seen until now.
Since you referred to another part of the documentation, it is possible that something is missing in that part or something was done in the wrong order. I’m not sure as I never had this error
