The 1.3 version of CronOTask for Mac was available as a free download on our website. The software belongs to System Tools.
From the developer:
CronoTask allows you to specify an unlimited number of programs to launch when your Mac server is unattended, with a very easy and fast to use interface. All the tasks to launch are listed in a table, with a double click on a row you can define in details how many times and when to launch the referred task (program, document, applet) selecting it from the HD, and using for the schedule a daily, weekly, monthly and even yearly plan.
