Since cron
is no longer supported on MacOS you have to use the provided Launch Agent instead launchd
.
This is done by adding configuration file in plist format (XML) to a directory in your library structure, e.g. ~/Library/LaunchAgents/
.
The following example updates my local CPAN::Mini mirror every day at 12:00 AM.
Filename: com.jonasbn.minicpan.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"

All launchd jobs are skipped when the computer is turned off or asleep; they will not run until the next designated time occurs, if the computer is turned on or not asleep.
