Ext2 Filesystem enables the use of Linux Ext2 formatted hard disks, floppies, CD-ROMs, etc., from within Mac OS X. Includes support for reading, writing, formatting, etc.

What's New

Version 1.4d4:
  • Bug Fix: With a particular rename usage, it was possible for directory entries to be lost.
  • Added partition probe type support for "Linux". This should enable automatic GUI mounting for those having problems with previous releases.


Mac OS X 10.3.9 or later

I have (HAD! >:-< ) a triple-boot (Mac, Windows, Linux) setup on an Intel Core Duo Mac Mini.

I previously tried Ext2 Filesystem back at 1.4d1, and it merely didnt' work.

Now I downloaded 1.4d4, and when I tried to mount the ext3 it fried my Linux filesystem! And since the FAT32 patition comes after that, it takes forever to see the Windows partition.

I'll have to boot from a Linux boot CD to see if I can repair it, or barring that, hopefully just erase that partition.

Another user who posted over on VersionTracker.com reports that it fried his entire hard drive. Sometimes I discount negative software reports on these sites, but not on this one.

(Really, Apple should take a break from putting in more flashy eye-candy into Mac OS and focus on the meat & potatoes things like fully mounting ext3 volumes....)

great extension for everybody sharing hard drive partitions or external drives with gnu/linux systems. alas, the current version (1.4d1) seems instable and causes kernel panics several times a day on my current system (powerbook w/ 10.4.6) and should thus be considered experimental. i sincerely hope it will achieve again at the solid stability it had back then when running on panther.

Only doc on tiger is in the package which states that 10.4.x is not supported. CVS and web site seem quite dead.

I could not get this to work.
I formatted a 40 gig disk in my linux (redhat rel 9) using mkfs -t ext2 /dev/hdb1
and using
mkfs -t ext2 -j /dev/hdb1

both times I would get an error when I tried to mount it on the mac.
I tried different drives.

i've tried the driver on 10.3 using an ext3 formatted disk and it worked. anyway, leave out the -j to create an ext2 fs without journal.

I think this absolutely wonderful and extremely useful to someone like me. I was wondering if anyone is thinking about making a similar filesystem plugin for Reiser FS? That would be great!

Mount Reiser FS on Tiger would be very very nice!

Seems to work perfect, very easy: just add a linux disk, restart (well, you can also use the mount command), and voila!
Very handy if you want to get files from a (crashed) linux machine quickly! And it also contains utilities to repair damaged filesystems. It would be cool to have a GUI for those utilities (maybe one of the next releases?), but command-line also works.
