How to open a LUKS-encrypted drive on Mac

A Linux encrypted disk can contain useful files even when macOS cannot mount it. vmount can unlock a detected LUKS container using your passphrase, then mount its supported inner filesystem in Linux.

What you need

Use an Apple Silicon Mac running macOS 14 or later, your external Linux drive and a known, valid LUKS passphrase. Your Mac login password is not necessarily the disk passphrase. vmount is not a password-recovery tool.

Start with the free download to browse files in vmount. Pro costs $29 USD once and unlocks export, Finder access and user write operations. Unlocking encryption and mounting the filesystem are separate steps: a correct passphrase does not guarantee every disk layout will mount.

Unlock the disk in vmount

  1. Install and connect. Run the signed .pkg installer and open vmount. Connect the external drive; dismiss any macOS initialize prompt rather than formatting it.
  2. Mount the encrypted disk. In the disk picker, identify it by name and size; detected encrypted disks carry a LUKS label. Click MOUNT to connect it.
  3. Enter the disk passphrase. The encrypted-disk dialog shows the selected device and a PASSPHRASE field. Enter your LUKS passphrase and click Unlock.
  4. Check the unlocked filesystem. A successful dialog reports the filesystem, then vmount opens the mounted folder view. Browse to the files you need. If unlocking succeeds but mounting fails, check the inner filesystem and layout.
  5. Export with Pro and finish. Use Export... on a selected file or click FINDER for Finder access. Wait for transfers; if Finder is mounted, eject that view first, then use vmount’s disk EJECT before unplugging.

Common LUKS questions

The passphrase is rejected

Confirm the selected device, keyboard layout and passphrase, then retry. A disk can have a different passphrase from the Linux user’s login. If you no longer have a valid unlocking secret, vmount cannot bypass the encryption. Consult your original setup and backups; the cryptsetup FAQ explains LUKS access and recovery constraints.

Unlocking succeeds, but my folders are missing

LUKS is an encryption container, not the filesystem itself. The volume inside may use ext4, Btrfs or another layout. vmount has an LVM activation path that selects a mountable logical volume; it does not offer a promise of every logical volume or storage arrangement appearing. Compare with the original Linux system if the expected volume is missing.

Can I use this for forensic or damaged-disk recovery?

This guide is for normal access to a drive you can unlock. Do not assume the encrypted mount flow preserves the disk without changes: unlocking and mounting can change filesystem state. Use an appropriate imaging or recovery workflow when preserving the original disk is essential.

Should I format the drive to make it readable?

No. Formatting erases the existing structure instead of opening it. If you need the existing files, keep the drive intact and investigate the unlock or mount error. Do not send your passphrase in a support email.
