Update: More recently I've found that fuse-ext2 has problems with certain newer ext4 features, so instead it is better to use ext4fuse ( port install ext4fuse or brew install ext4fuse). If that doesn't work try: sudo ext2fuse /dev/disk1s2 /sys_mount_point But if you want to mount the partition into a system directory then you need to run it as root e.g: sudo mount -t fuse-ext2 /dev/disk1s2 /sys_mount_point It may complain about not being able to write to the log file but it should still mount the partition into your home mount point. Combine the diskX and partition number Y like this /dev/diskXsY - e.g: mount -t fuse-ext2 /dev/disk1s2 ~/my_mount_point This will list all partitions for all disks and amongst them you should see the relevant ones listed under the TYPE column as Linux. when installed using MacPorts port install ext2fuse) - then firstly you need to work out where the Linux partition is: diskutil list If you're wondering what the command line is to mount an ext4 partition using fuse and ext2fuse (e.g. The script is called with the partition name that you look up via diskutil list, e.g. Sudo mount -t fuse-ext2 '/dev/$1' '/Volumes/$1' To save some extra typing I use a tiny script which takes the partition name such as disk0s2 and mounts it under /Volumes/disk0s2, creating the folder if necessary: # mount_ext4.sh EXT2/3/4 mount script for older OSX versions (deprecated)

This method worked on mavericks, yosemite, el capitan and sierra.

The main osxfuse version probably needs some special installation parameter to enable MacFUSE compatibility, so until this is fixed in homebrew the manual DMG method should be used. Most likely, the DMG version ( Caskroom/cask/osxfuse) fails because homebrew installs the package with default settings, which means that MacFUSE Compatibility Layer is not included. There are two osxfuse packages in homebrew: # brew search osxfuseīoth versions fail to mount EXT partitions. Note: My suspicion is that the homebrew formulas did not work because homebrew installs osxfuse without the MacFUSE Compatibility Layer. Probably this can be fixed by fiddling with permissions, but I didn't look into it. Mounting as a regular user did not work for me. Mount the partition to an existing mount point: sudo mount -t fuse-ext2 /dev/disk0s2 /Volumes/ext4 disk0s2 in the example below, (UPDATE) in later MacOS versions ext3/ext4 partitions might be labelled Microsoft Basic Data and not Linux): 1: Linux_Swap 8.2 GB disk0s1 Once you have both OSXFUSE and FUSE-EXT2 installed you can mount the ext2/ext3/ext4 partitions as mentioned in other answers:įind the device name for the EXT partition you want to mount (e.g.

Manually download FUSE-EXT2 from or for Sierra/El Capitan from and run the PKG installer.

IMPORTANT: Once you launch the PKG installer, make sure you selected MacFUSE Compatibility Layer in the wizard (it is not enabled by default) - without it I was getting an error while trying to mount.

Manually downloading and installing the OSXFUSE DMG from.

The homebrew formulas for OSXFUSE and FUSE-EXT2 did not work for me on either mavericks or yosemite. T*wo packages are needed in order to enable EXT2/3/4 support on OSX: OSXFUSE and FUSE-EXT2. Original answer for Yosemite and older *(deprecated) If you happen to have files owned by _lpoperator (apparently they are created when you use rsync with preserve group option), then the following command will allow accessing those files: /usr/sbin/dseditgroup -o edit -a everyone -t group _lpoperator diskutil umount /dev/disk2s1 - if you get a message that unmounting failed then you can force unmounting with diskutil umount force /dev/disk2s1, although it would be cleaner to close the apps that are using the files on the disk and retry unmounting without force. Sudo ext4fuse -o allow_other /dev/$disk_id $'' Read -p 'Please type the EXT4 device identifier: ' disk_id When launched it will automatically create the mount point after you'll be prompted to enter one of the displayed device identifiers such as disk2s1: diskutil list Here is a bash script which partially automates the process.

You can mount as a normal user but in that case you'll only be able access world-readable files, that's why for full access you need to use sudo, e.g.: sudo ext4fuse -o allow_other /dev/disk2s1 Install ext4fuse with: brew install ext4fuse While other answers already give some usage examples I'll repeat it once again with some important details: Updated answer for (High) Sierra and more recent MacOS versionsįor Sierra and High Sierra ext4fuse seems to work well for read access only and therefore it could probably be considered the preferred option.
