What this error means

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? docker: permission denied trying to access /var/run/docker.sock on macOS is a Docker failure pattern reported for developers trying to macos developer cannot run docker commands after system update or docker desktop restart; socket file permissions broken after macos upgrade. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Classic persistent issue on macOS platforms. Docker Desktop frequently loses socket permissions after macOS updates, requiring manual chown or fix-docker-permissions.sh. Very high search volume evergreen topic. Category mapping: Docker is explicitly listed as approved category. High commercial value: developers paying for Docker Desktop subscription blocked from container operations.

Common causes

Quick fixes

  1. Confirm the exact error signature matches Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? docker: permission denied trying to access /var/run/docker.sock on macOS.
  2. Check the Docker account, local tool state, and provider configuration involved in the failing workflow.
  3. Compare the failing environment with a known working setup, then change one configuration value at a time.

Platform/tool-specific checks

Step-by-step troubleshooting

  1. Capture the exact error message and the command, editor action, or request that triggered it.
  2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
  3. Review the source evidence below and compare it with your environment.
  4. Apply one change at a time and rerun the smallest failing action.
  5. Keep the working fix documented for the team or deployment environment.

FAQ

What should I check first?

Start with the exact Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? docker: permission denied trying to access /var/run/docker.sock on macOS text and the smallest action that reproduces it.

Can I ignore this error?

No. Treat it as a failed Docker workflow until the root cause is understood.

Is this guaranteed to have one fix?

No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.

How do I know the fix worked?

Rerun the same command, editor action, or request. The fix is working when that action completes without Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? docker: permission denied trying to access /var/run/docker.sock on macOS.
