libxpc / launchd are not open-source

Number:rdar://31842314 Date Originated:26-April-2017 07:33 PM
Status:Open Resolved:No
Product:macOS + SDK Product Version:macOS 10.12.4
Classification:Enhancement Reproducible:Not Applicable
As part of the macOS / Darwin boot process, the program launchd is required to launch background tasks and daemons. From early releases of macOS, up until (and including) OS X 10.9, this has been released as an open source project. Since OS X 10.10, launchd has been rewritten and moved into the closed-source libxpc project. The Darwin operating system now has no replacement for launchd, and past versions cannot be used, due to their dependencies on libxpc. It would be great if libxpc could be open-sourced, as it would greatly benefit many open-source groups.

Steps to Reproduce:
1. Visit

Expected Results:
There should be different folders for each version of libxpc that corresponds to a macOS release, each containing the source code to libxpc (and thus launchd).

Actual Results:
A 404 error occurs, as libxpc is not open-source.

I was wondering if there was any chance of the source code for libxpc being released for macOS 10.13. Thank you for your help with this bug report, Ethan Sherriff (PureDarwin Team).
