Did chmod +xr /usr/local/bin and the problem finally resolved!
Deemone@Deemone ~ % ls -ld /usr/local/bin
drwxr-xr-x 25 root wheel 800 Apr 19 14:15 /usr/local/bin
After reboot Docker’s and Kubernate’s commands are accessible and even Kubernete’s context menu works like a charm. So this is resolved too now: https://forums.docker.com/t/unable-to-run-embedded-kubernetes-on-docker-desktop-mac/135652
You are Godlike! Thank you so much!
The issue is resolved.
