As the error indicates, mosh-server was not found at startup.  That's
because the program is installed as /usr/local/bin/mosh-server, but that
directory is not included in the default PATH for login sessions.

  mosh --server=/usr/local/bin/mosh-server rhimac

should work, or you can set PATH to include this directory in your shell
startup scripts.

Also, the OS X firewall may pop up an allow/deny dialog the first time
you try and run mosh-server, so you need to be at the Mac to click on it.

This has nothing to do with either ssh or mosh; your Mac simply isn't
finding 'lenovo7'.  The typescript of your ssh-to-rhimac session above
suggests you might have a typo in its naming somewhere and it might be
'levono7' on your network.  This seems to be a fairly common typo with
the Lenovo name.
