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.
