You're experiencing at least two issues here. First there's the OSX bug with your window manager permissions. You need to run headless on OSX, as you already determined, so make sure you continue to do that. (The bug is reported here: https://issues.jenkins-ci.org/browse/JENKINS-15697).
Add this to the slave command line options: -Djava.awt.headless=true Secondarily it seems like perhaps the slave node may not be properly configured within Jenkins? Have you tried a combination of SSH + running headless (perhaps that was your error message you included)? I hope this helps, Kenny On Tuesday, April 30, 2013 5:28:11 PM UTC-7, Dan Tenenbaum wrote: > > Hi all, > > I have tried a number of methods to connect to a Mac slave and have had no > success. > > My master is also a mac and it's called dhcp151178.
