Configure the Trend Micro Security (for Mac) server to regularly check its update source and automatically download any available updates. Using scheduled update is an easy and effective way of ensuring that protection against security risks is always current.
After the server finishes an update, it notifies agents to update.
For daily, weekly, and monthly updates, the period of time is the number of hours during which Trend Micro Security (for Mac) will perform the update. Trend Micro Security (for Mac) updates at any given time during this time period.
For monthly updates, if you selected the 29th, 30th, or 31st day and a month does not have this day, Trend Micro Security (for Mac) runs the update on the last day of the month.
