Real-Time Disk Mounting Control

Watch for disk mounting events as they happen and control which physical drives and disk images are allowed to mount

Flexible Rule Matching

Build rules using exact matches, partial matches, exclusions, regex, volume names, UUIDs, and media-type targeting

Smart Triggers

Choose to show alerts, display notifications, play sounds, run shell scripts, launch apps, open URLs, or simply log when a matching disk mount event occurs

Block Unauthorized installers

Works with DMG disk images, making it useful for tightening control over untrusted software installers
