Regularly updating ESET Endpoint Security for macOS is necessary to maintain the maximum level of security. The Update module ensures that the program is always up to date by downloading the most recent detection modules.

Click Update from the main menu to view your current update status including the date and time of the last successful update and verify if an update is needed. To begin the update process manually, click Update modules.

Under normal circumstances, when updates are downloaded properly, the message "Update is not necessary – the installed modules are current" is displayed in the Update window if you have the latest modules. If modules cannot be updated, ESET recommends that you check your update settings. The most common reason for this error is incorrectly entered license data or incorrectly configured connection settings.

The Update window also contains the Detection engine version number. This numeric indicator is linked to the ESET web site that displays Detection engine update information.
