Key Features
Real-Time Disk Mounting Control
MountBatten watches for disk mounting events as they happen, giving you control over which drives and disk images are allowed to mount
Zero-Trust Storage Protection
Create a zero-trust environment by blocking storage devices or disk images even if macOS would otherwise allow them to connect
Block Unauthorized Installers
MountBatten works with DMG disk images, making it useful for blocking installers and tightening control over untrusted media
Flexible Rule Matching
Build rules using exact matches, partial matches, exclusions, or a Regex; target all media, disk images only, or physical disks only
Smart Triggers and Automation
When a rule matches, MountBatten can show an alert, display a notification, play a sound, flash the screen, launch an app, open a URL, run AppleScript, or simply do nothing (but log the event)
Activity Logging
Review recent activity in the built-in Event log
Compliments macOS' "Allow connection" prompt
MountBatten can work in tandem with macOS's built-in device security and can even block physical drives from mounting that macOS trusts
Lightweight & Efficient
MountBatten is very lightweight and memory efficient, making it easy to leave running in the background
Privacy-First
No data ever leaves your Mac; everything is stored and processed locally
