Xserver and nolisten TCP
Mac preferences (initializations) are called plists and are stored
in /Users//Library/Preferences
In this directory, com.apple.x11.plist is the relevant one. To view,
- defaults read com.apple.x11*
nolisten_tcp was set to "1", I changed it to "No" like this:
- defaults write com.apple.x11 nolisten_tcp No*
via web suggestions:
http://lists.apple.com/archives/x11-users/2005/May/msg00073.html
and http://plone.jcu.edu.au/hpc/user-guides/x-environment-for-osx/
but executed slightly differently.
