Mac OS X 10.6 or newer running on 64-bit Intel hardware
Mac OS X version 10.9 installs with a default setting that breaks the multi monitor functionality of the ThinLinc client. A workaround to this problem is to disable setting "Displays have separate Spaces" in settings for "Mission Control" found in "System Preferences" .
The client for Mac OS X can be found in the directory client-osx in the Client Bundle. To install the client, follow these steps:
Double-click on the file tl-4.8.1_5456-client-osx.iso.
Drag the "ThinLinc Client" application to an application folder of your choice.
Eject "ThinLinc Client".
To start the ThinLinc Client, double click on the client application. The client can also be added to and started from the Dock.
The Alt key (also know as the Option key) behaves very differently on OS X compared to its behaviour on other platforms. It closely resembles the PC AltGr key, found on international keyboards. ThinLinc therefore treats these keys in a special manner on Mac OS X in order to provide a good integration between the client and the remote ThinLinc system.
Whenever either of the Alt keys are pressed, ThinLinc will behave as if AltGr was pressed. The left Command key is used as a replacement for Alt in order to use shortcuts like Alt+F. The right Command key retains its behaviour of acting like the Super/Windows key.
