Unauthorized Access when saving file at MAC OS X

Hello,

We have a SL4 Business application that is running for a couple of years now. Recently we reported problems from some customers running MAC OS X.

The problem arises when the user tries to save a file our application produces. More specifically, it seems the problem started after the MAC OS X update 10.9.

My Silverlight app shows the following error

[UnauthorizedAccess_IODenied_Path]

My customers tried to save the file in different locations, but no success.

How can I fix that?

Thank you,

Igor.

Hello,

As you may know, Mavericks added a sandbox type mode for plugins. For this error, firstly, I would like to suggest you update your Silverlight to latest version and check if it works.

In addition, please try the following setting in your user client side.

Safari/Settings/Security/Internet-Plugins:Allow Plugins -> Organize Website Settings... select Silverlight on left side, on right side select hostname, pulldown 'Execute in unsecure mode'

There are two other issues when using Silverlignt on Mavericks, please have a reference
