Aegis 2.01 for Mac is a small security utility by developer Jiulong Zhao (dragonBTV), sold through the Mac App Store. Its job is narrow but important: it protects your Mac from data being copied onto external storage. Any USB, Thunderbolt or FireWire drive, flash stick or SD card that is not on your own pre-set whitelist is blocked when plugged in, while trusted devices connect normally with no delay.

It suits anyone who uses a Mac in a shared office, classroom or studio, where a flash drive is still the simplest way files get stolen. You can even allow or block individual partitions of the same disk. Aegis itself is password-protected, with the password stored in the macOS Keychain, and the whitelist is stored in protected form so it cannot be quietly edited.

Key Features

  • Blocks any external storage device that is not on your whitelist
  • Covers USB, Thunderbolt and FireWire drives, flash sticks and SD cards
  • Block or allow individual partitions of a single physical disk
  • Simple whitelist enrolment: open preferences, plug the device in, unplug it
  • Password-protected settings with the password saved in the macOS Keychain

How to Download

  1. Search the Mac App Store for Aegis by dragonBTV, as this older version's listing could not be verified live; avoid third-party installers.
  2. Install the app, set your password, then plug in each trusted drive once to add it to the whitelist.

Is Aegis free?
Aegis was a Mac App Store app by dragonBTV. We could not verify a current live listing or price for version 2.01, so check the App Store directly rather than trusting sites advertising it as a free download.

Does Aegis block my own drives too?
Only until you trust them. Whitelisted devices mount automatically with no delay; anything unknown is blocked, and you can reset the trusted list in the app to start over.
