I have also tried -X instead of -Y. The remote machine is running OSX 10.4.10. I am using Ben's latest release, and I am not setting my $DISPLAY anywhere (I do have the remote machine's display set in a .bashrc file, but that shouldn't matter right? Anyway, I get the following error when I connect:
Warning: No xauth data; using fake authentication data for X11 forwarding.
Just following up on this last point: That message can have several causes, but in this case you will always see it if ssh is locally connecting to X11 using the launchd socket. It's harmless, because we don't use xauth authentication for launchd connections.
(Technical explanation: We had to disable launchd support with xauth because there's a race condition where the first X client that caused X11 to start would try to read ~/.Xauthority at the same time the newly-started Xquartz was writing it. Since we can assume that only the local user on the local machine has access to the launchd-created socket, we can safely bypass xauth authentication for that case.) -- Ben Byer CoreOS / BSD Technology Group, XDarwin maintainer
