It is usable for the vast majority of users. If it is causing an issue please file a detailed bug report, with diagnostic ID, also try the Edge releases, and give some information about what you are actually running, for example how to replicate it. Most of the bug reports in that thread are totally unhelpful. Quite likely it is not even the same cause for different people, as some people said it was fixed on Edge while others did not. Even a single well thought out detailed bug report would make it much easier to investigate the issue.
Are you sure it works for vast majority of users? At least in my developers circle who use macOS for web* development - all of them have issues with docker high cpu usage due IO. Some use docker-sync to go around the issue.
As for bug reports - zero feedback from anyone on that thread from maintainers. If you are one of the maintainers - it might be good to write this comment on that thread instead of HN
* - I understand that web developers might be a small percentage of users and my case doesn't represent everybody
I am not a maintainer but do work on LinuxKit which is used. If docker-sync helps, then that suggests that you have an issue specifically related to file sharing. Please file a new issue, do not add to this one, which explains how to reproduce your development setup. Different setups work very differently (eg polling vs notifications), and people use things very differently, there is no one set of tooling and setup that is "web development", but it sounds like in your company you all use similar tools and setup, so it is not surprising you all have the same issue. We have a performance guide here https://docs.docker.com/docker-for-mac/osxfs/ that covers some use cases.
I have 60-65% CPU usage at idle - it's not ideal for battery life but it is usable and I'd say it's easier to use than minikube (which is something that I also use a lot). This is very early for DfM + K8s - I'd say the usability outlays teething issues.
If you want to help send in diagnostic reports for the Docker guys.
