Mac OS X: Read Linux ext3 / ext4 External USB Hard Disk Partition

15 Feb 2023Best/Tutorial

By default, macOS does not have native support for reading Linux ext3 or ext4 file systems. However, there are third-party solutions available that can enable you to read these file systems on your Mac. Here are a few options:

Install FUSE for macOS and a compatible file system driver:
- FUSE (Filesystem in Userspace) is a software interface that allows non-privileged users to create their own file systems without requiring kernel modifications.
- One of the most popular FUSE file system drivers for macOS is "ext4fuse", which allows you to read ext4 file systems on your Mac.
- To install FUSE and ext4fuse, you can use the following commands in the terminal:
```
brew cask install osxfusernbrew install ext4fuse
```
- Once installed, connect your external hard drive to your Mac and mount the ext4 partition using the following command:
```
sudo ext4fuse /dev/disk2s1 /Volumes/ext4disk
```
  Replace /dev/disk2s1 with the appropriate device identifier for your external hard drive's ext4 partition, and /Volumes/ext4disk with the mount point of your choice.
Use a commercial file system driver:
- There are also several commercial file system drivers available for macOS that provide support for reading ext3 and ext4 file systems, such as Paragon ExtFS and Tuxera NTFS for Mac.
- These drivers typically offer more advanced features and performance than open source solutions, but they come with a price tag.
- Once installed, your external hard drive's ext3 or ext4 partition should be automatically recognized and mounted by your Mac.

rnNote that while these solutions allow you to read ext3 and ext4 file systems on your Mac, they do not provide write support out of the box. To enable write support, you may need to configure your file system driver and mount your partition with write permissions, but this comes with additional risks of data loss if something goes wrong during the write process.
