I tried to install ssm-agent on my mac following https://docs.aws.amazon.com/systems-manager/latest/userguide/manually-install-ssm-agent-macos.html

But when I tried to use it aws ssm start-session --target i-xxxxxxxx --region us-east-1 --profile myprofile
I still keep getting an error :

SessionManagerPlugin is not found. Please refer to SessionManager Documentation here: http://docs.aws.amazon.com/console/systems-manager/session-manager-plugin-not-found

when I tried to check the log tail -f /var/log/amazon/ssm/amazon-ssm-agent.log

I see below error

        status code: 403, request id:

Any idea what should I do?
