Start by reproducing the failure with the supplied `packer build macos.json` configuration, focusing on the `vmware-iso` and `virtualbox-iso` builders and the SSH verbose output. No source file or test is named; done would require identifying the cause of the handshake EOF and demonstrating a successful SSH connection or a clearly scoped fix.
