What do they mean "resetting environment variables"? Can you please provide the output of 'env' in the working or not-working case. This really sounds like an environment issue, and I wouldn't be so quick to accept your users claims that it is not.

Right. That was due to a slew of security advisories released by freetype and the png project, but as far as your code is concerned, those three versions (2.5.1 through 2.5.3) should look pretty much the same.

Yeah, this was because 2.5.1 was the version that started building libX11 with --with-xcb, thus exposing the same bug in XView that was exposed on Linux.

They should be using the launchd socket, which doesn't use xauth.
Still, all this would be much cleared if we could see the output of 'env' for a working and non-working case and work from there...
