I found that even setting the PATH environment variable for the node didn't work for the hombrew Mercurial installation. The path WOULD get set, but only for the script build phase, not for the VCS checkout phase. Here's what I wound up doing.

1. Go into Manage Jenkins -> Configure System
2. Add a new Mercurial Installation
3. Name it whatever you want (I named mine build-mac)
4. For Installation Directory I put /usr/local
5. The Executable parameter was pre-set to INSTALLATION/bin/hg, so I just left it at that.
6. Everything else in here can be left blank
7. Go into your job and edit the configuration
8. Under Source Code Management set Mercurial Version to the mercurial installation you just added.
9. Save
10. $$$

Hope that helps anyone else running into this same problem, now that we're not allowed (by default anyways) to do anything inside of /usr/bin anymore. Previously I would have just symlinked hg there, but now with the new "System Integrity Protection" "feature", that's no longer as trivial of task, and even more difficult if your Mac slave is headless.
