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: Started by user anonymous Building in workspace /Users/Shared/Jenkins/Home/jobs/nohup/workspace [workspace] $ /bin/sh -xe /var/folders/rj/xt96v6dd5ls7v94142grnvn400007b/T/hudson3605439247319045393.sh + nohup find / -L -type l nohup: can't detach from console: Inappropriate ioctl for device Build step 'Execute shell' marked build as failure Finished: FAILURE

Jesse Glick added a comment - 2014-12-03 03:35 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 .
