Cannot mount TCP/IP instruments in NI-MAX for Mac OS-X (GPIB/USB/Serial Port are all OK)

[MacNIMaxUser1]

I cannot seem to "mount" a TCP/IP based instrument in Ni-MAX for Mac OS-X. The NI-MAX for MAC looks quite different than that for a Windows OS. 

(i) Mounting GPIB/USB2/Serial Port (RS232) instruments in MAC OS-X NI_MAX has been OK

(ii) Mounting all instrumentation in PC/Windows based NI-MAX including TCP/IP instrumentation has not been of a problem

In the picture below of NI-MAX in MAC OS-X, many of the common side buttons, including the Device/Network Devices are missing (compared to the version of Windows). Can anyone having used MAC based NI-MAX and TCP/IP instrumentation therein tell me how to get the instrumentation to appear in the list?

The menu items don't have the Devices->Network options either.

Many thanks for the comments and help, in advance.
