How to open an ext4 drive on Mac
Have a Linux USB drive or SSD that will not appear in Finder? macOS does not natively mount ext4. vmount lets you browse its folders on an Apple Silicon Mac, without installing a kernel extension or changing SIP.
Start by browsing for free
Download vmount free and check whether it can open your drive. Free mode lets you browse in vmount with read-only access. Pro costs $29 USD once and unlocks file export, Finder access, writing and formatting. You do not need to upgrade just to see your folders.
You need macOS 15 or later and an Apple Silicon Mac. This guide is for an existing ext4 partition on an external drive. Formatting is a separate operation that erases data; it is not part of opening a drive.
Open your ext4 drive step by step
- Install and open vmount. Download the signed .pkg installer, run it, then open vmount from Applications. You need an Apple Silicon Mac running macOS 15 or later.
- Connect your ext4 drive. Connect the external drive. If macOS offers to initialize it, dismiss the prompt. Initializing or formatting is not needed to read your existing files.
- Mount in read-only mode. Identify your external disk by its name and size. Keep the lock closed for read-only access and click MOUNT. Free mode is read-only. Open the ext4 partition in vmount and browse your folders.
- Export files or open Finder with Pro. Pro unlocks file export and Finder access. To save a file to your Mac, select it in vmount and choose Export... from its context menu. To browse the mounted drive in Finder, click FINDER. Keep read-only access selected if you only need to read files.
- Eject before unplugging. Wait for transfers to finish. If you mounted in Finder, use its EJECT control to unmount that view, then use vmount’s disk EJECT control to return to the picker before unplugging the drive.
With Pro, you can enable read/write access using the lock control before mounting. Start read-only to confirm that you have selected the right disk; enable writing when you need to create, rename, delete or copy files onto it.
If the drive does not open
The USB drive is missing from vmount
Check its cable, power and enclosure connection. Look for the physical device in Disk Utility using View → Show All Devices. If the Mac cannot detect the device, try another port or enclosure before troubleshooting ext4. Quit and reopen vmount after reconnecting the drive.
The partition is not labeled ext4
Linux disks can contain several partitions. Match the partition to the one you used on Linux rather than assuming the first partition holds your files. An encrypted LUKS container must be unlocked with its passphrase before its inner filesystem can be opened.
The drive was not cleanly unmounted
An interrupted write or damaged filesystem can prevent mounting. Note the error message and avoid formatting a drive that contains files you need. If possible, reconnect it to Linux for a filesystem check while the partition is unmounted. See the ext4 recovery guide for next steps. Opening a drive is not a guarantee of recovering damaged files.
A file cannot be opened or copied
First check your access mode and license: Free is read-only browsing; file export and Finder access require Pro. Linux ownership and permission settings can also limit access to particular files. If one folder fails while others open, check that folder’s permissions on the original Linux system before changing them.
Transfers take longer than expected
Speed depends on the drive, enclosure, connection, file sizes and workload. Copy a small representative folder first. Avoid disconnecting the disk while a transfer is running.
How vmount opens ext4
vmount uses Apple’s Virtualization.framework to run a small Linux virtual machine. Linux mounts the filesystem, and vmount provides a file browser on your Mac. Pro’s FINDER control exposes the mounted files through a local NFS connection. You do not need to install a macOS ext4 kernel driver or change SIP settings.
Linux permission and ownership rules still matter. Copying files onto a different Mac filesystem does not guarantee that every Linux metadata field or special file will be represented the same way.
