Mac OS X 10.11 Removes /usr/bin/lockfile

Dave Nanian:

Little did we know that there was a shoe preparing to drop (although perhaps the fact that it was in /usr/bin was a hint): in El Capitan B4, Apple decided to stop shipping Procmail, and with it, lockfile. It wasn’t deprecated and then removed… it was unceremoniously sent to the bit bucket. So, as of B4, scheduling in El Capitan broke.

[…]

In the end, we did none of those things. Instead, since Procmail is Open Source, we changed our build process to build lockfile as well, and included that command, unmodified, in our bundle.

[…]

This also meant we had to change the scripts that were looking for lockfile to find our application bundle and call the new, “local” version of lockfile instead. And that means, unfortunately, that users have to delete and recreate their schedules.
