@smlambert I'm splitting this out because the solution is different

Thanks @sxa555, appreciated!

Try XQuartz

@gdams and I initially tried using xquartz but didn't manage to succeed within the jenkins environment for the JCK but we haven't got back to working it further again - if you have knowledge/experience of it @jdekonin that would be great :-)

@sxa555 I don't have experience running via jenkins on osx, so I can't help there. But that comment leads me to believe that if you ran manually and not through a jenkins agent/environment that it was working??

I think so yeah but it was a while ago :-) The xquartz server is probably still on the box I was using for testing

I'm not convinced it helps, but I found this conversation in another community that talks about this issue. I'll keep digging.

So I just typed which Xvfb on my macbook. It returned /opt/X11/bin/Xvfb. On most Unix systems it's in /usr/bin/Xvfb. I'm probably being naïve here, but is it not as simple as doing something with the path, or setting up a symbolic link?

@geraintwjones No idea -you tell us - does it work? ;-) I don't mind whether it's called Xvfb or xvfb

@smlambert A thought - do we require remote access to your mac GUI display to be able to run GUI tests? (Ref: #267 which I've raised for JCK purposes)
