On macOS 15 Sequoia, there is a new Legacy Background Tasks toggle in System Settings > Login Items & Extensions.

It seems to initially appear (in an "on" state) when an app tries to install a launchd job and places a launch plist in /Library/LaunchDaemons.

I have not found any effects of turning this toggle off. I still seem to be able to happily use launchctl bootstrap and launchctl bootout, for example.

What does this toggle do? Is there a WWDC session or documentation I haven't found yet?

This toggle is meant to control whether cron jobs will be able to run.

Further details and documentation should be available later in the beta cycles.
