Scanning MAC OS

Attempting to scan mac, but we cant get it configured its not just any mac its an image with ip and all. Anyone having issues with this?

Network or Agent
Is port 22 Open on the MAC and allowing Connections
Are you using SSH Key or UN/PW
Are you using Scan Assistant, if So do you see port 21047 open

We went with the agent and its shows in the console now with he agent applied. But we did try the network way we opened 22 credentials were not successful…Using SSH key
