Scheduling Preference Settings
The settings for the scheduler behavior can be found on the General panel in Preferences. The Scheduling Behavior options are listed below:
Use background scheduler – Enable this option to run scheduled documents even if ChronoSync is not running.

Wake system to synchronize – Enable this option to wake your Mac from sleep when a synchronization is scheduled to occur.

Run scheduled items synchronously – Enabling this option will allow only one scheduled synchronization to run at a time. When disabled, the scheduled synchronizations will run concurrently.
