macos docker not starting code example
Example: docker not starting mac
On a supported Mac, run:
brew install --cask docker
Then launch the Docker app. Click next. It will ask for privileged access. Confirm. A whale icon should appear in the top bar. Click it and wait for "Docker is running" to appear.
You should be able to run docker commands now:
docker ps
Because docker is a system-level package, you cannot install it using brew install, and must use --cask instead.
Note: This solution only works for Macs whose CPUs support virtualization, which may not include old Macs
