Extended desktop on Mac OS X
The extended desktop functionality is not available on Mac OS X. Creating a virtual extended desktop (i.e. an extended desktop without a second physical monitor connected to the computer) is not supported in this Operating System.
Since it is not supported natively, this functionality would require the installation of a driver. The ClickShare client application completely relies on drivers already existing in the operating system, so the user does not need to install anything before using it. Therefore, installing a driver on Mac conflicts with our "ease of use" philosophy.
