Diagnose the host
Run:
sbxm status --globalThe check is read-only and covers:
- macOS version and arm64 platform
- required commands such as Docker, Git, SSH, and
sbx - Docker Engine reachability
- Docker Sandboxes CLI version, login, daemon state, and network policy
- Remote SSH configuration for sandbox connections
Fix the reported prerequisite, then run global status again. sbxm does not infer that an unobservable requirement is safe.
If a command reports sbx-login-missing, run sbx login, then retry it. Commands that use Docker Sandboxes check this before displaying the project selection prompt. sbx-login-unobservable means the authentication probe failed for another reason, such as an unavailable daemon; inspect the original failure shown with the diagnostic. sbxm status --global can still diagnose the host while signed out.
