Interesting.  Have a look in these directories:

If you have stuff there, it must have been populated by mozroots, or something.  I understand that the latest packages distributed by mono repositories have automated cert-sync in linux during package installation, but that's not yet present on OSX.  So on OSX, mozroots or something is necessary to populate the root Trust.

If you don't have those directories - or if they're empty - it will raise new questions about differences between WebClient().DownloadString() versus SslStream.AuthenticateAsClient().  I am using the latter, on mono 3.12 MRE for OSX.
