Mac Mountain Lion Compatibility With Windows Home Server 2011, Small Business Server 2011 Essentials and Windows Storage Server 2008 R2 Essentials
Applies to

  “Small Business Server 2011 Essentials”, “Windows Home Server 2011” or “Windows Storage Server 2008 R2 Essentials”.

Mac OS x10.8 (Mountain Lion) is supported by client connector for the above 3 products.  However, there are several compatibility issues reported.  While we are actively working on further resolutions, we recommend following steps to workaround these issues.

1. An error meesage pops up when deploying connetor: “’Connector for Mac’ can’t be opened because it is from an unidentified developer.”

After downloading the connector, double clicking the connector for mac, you will get an error dialog, indicating  that the application is not from an identified developer.
This is caused by the Gatekeeper, a new feature of Mountain Lion, that requires applications to be signed by identified developers.


  1. Please turn the Gatekeeper off beofre running the connector.
  2. You will need to go to security & privacy, select “Anyway” for “allow applications downloaded from” to turn this feature off. 
  3. You can turn it on back after installation done.
2. Dashboard cannot login after correct credential is entered


    After entering the user credential, user cannot login to dashboard, 
the login page hangs.
    To further confirm the issue, you could also check the log file In the /library/logs/Windows Server.log in console, the error info should be like this:
  Jul 30 14:18:28 colorados-Mac-mini.local WSL[983] <Error>: /Users/xcbusr/macbuild/Request/9AA878B8-1898-4BEA-8BA9-  0B5091CFCEE7/MacUtils/ServerConfig.m:186 Failed to load server configuration file - The requested URL was not found on this server.
   This is caused by the API change in Mountain Lion which does not compatible with previous one.
