I'm receiving an "osIntegration.mount() failed" error (see below) when trying to connect using my custom handler in Drive. This error only happens on the Mac.  Connection to the same CMS through Windows 7 works perfectly.  The error seems to be related to the URL entered in Drive.  For example, if I enter

      icms://mobiledemo.flatironssolutions.com:8443/icmsserver/repo

I get the error.  However, if I enter

     icms://mobiledemo:8443/icmsserver/repo

it works.  So at first, it appears to be related to entering a fully qualified host name.  However, I have also see it fail on a different host without a fully qualified name (e.g, icms://mtcdmtl601:8080/icmsserver/gpp_dev_repo01).  It is consistent in that if a URL works, it will always work; if it fails, it will always fail.

Here's the error from the log file:
