This is often tricky even within the University network.

tv=local  should open an X-windows window on the Mac.  Try opening some 
other sort of window - e.g. in the desktop window at command line type 
xclock &.  That should bring up a clock face - or xload & a load meter.

Your Macbook may be recognizing that it is on a foreign net and erecting 
firewalls.

Is AIPS installed on the Macbook?  If so, try starting aips so that the 
TV comes up.  Then on the desktop say tvok and not tv=local in the aips 
command line.  It will try using your ssh connection to an inet socket 
which may not be forbidden while a command to run a command 
(START_TVSERVERS) on your Macbook may be viewed as too dangerous.

Our systems guy is out riding his bike in the Northwest so we will have 
to wait until next week for more expert advice.  When you send more 
questions please send all of the messages that come up (if any) to help 
in the diagnosis.
