nope.
that's not the problem. the command (export DISPLAY=macbox:0 for bash or setenv DISPLAY macbox:0 for C shell) has to be entered in the OTHER unix box to export the display to the mac or any other computer I am working with. It works for alls unix or linux systems, just not for the Mac.
The question is, how to modify MacOsX to allow other unix systems to export the display.
thanxs anyway
