BitBridge - Open-source BitLocker for Mac Apple Silicon

External encrypted Windows SSD connected to a Mac with secure mount visuals

What It Solves

macOS cannot natively open BitLocker-encrypted Windows drives. BitBridge helps MacBook Air and MacBook Pro users on M1, M2, M3, and M4 access a Windows laptop SSD or external NVMe enclosure from Finder.

GUI setupChoose the external Microsoft Basic Data partition from a simple installer.

Keychain storageThe recovery key is stored in macOS Keychain, not in scripts or LaunchAgents.

Read-only mountThe default mount mode is read-only to protect the original Windows disk.

Requirements

Apple Silicon Mac: M1, M2, M3, M4, or newer.
macOS 13 Ventura or newer recommended.
anylinuxfs installed at /opt/homebrew/bin/anylinuxfs.
macOS tools: diskutil, hdiutil, launchctl, security, osascript, sudo.
A valid BitLocker recovery key for the drive.
