            JIRA link daemon is apparently dead again.

            Hmm. Well, I am pushing a workaround. Someone with a Mac able to reproduce this, please test this build. Not just that you can run shell scripts on a Mac node from a workflow, but that they indeed survive a Jenkins restart or slave disconnect if it is e.g. sleep 100.

            If Apple uses modified utils, their sources are on opensource.apple.com. For nohup, it's here (newest version):
            http://www.opensource.apple.com/source/shell_cmds/shell_cmds-179/nohup/nohup.c

            It's an error in _vprocmgr_detach_from_console which indicates the mode of installation and running Jenkins may indeed be relevant, as I know it in the context of disconnecting a process from a user session (see e.g. explanation https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard).

            When installing Jenkins via installer on a virtual machine with OS X 10.7, and installing Workflow Aggregator with dependencies, the job just stops after

            [workspace}Running shell script

            10.7 is ancient, but it appears there's something wrong with using nohup this way. In fact, if I run a shell script with e.g. nohup find / -L -type l, I get:
