As usual, not that immediate to find a proper answer on the ‘Net, hence I’m providing one here.

While in Snow Leopard was quite easy to see your ext2/ext3 formatted disks via MacFuse and ext2-fuse, in Lion you need to install another fuse fork and select a special option. That new fork is OSXFUSE, which latest release at the time of this post if from December 2011.

The most common symptom indicating you need this is to try mounting an ext2/3 formatted drive and see the following error:

fuse-ext2 /dev/disk3s1 /Volumes/Movies
dyld: Library not loaded: /usr/local/lib/libfuse.2.dylib
 Referenced from: /usr/local/bin/fuse-ext2
 Reason: image not found

During the installation of OSXFUSE, you need to enable MacFuse Compatibility Layer by flagging the appropriate checkbox as shown below:

Once you’re done with this, replug your ext2/3 formatted drive and it’ll automagically mount it in Finder, giving your deserved magnificent user experience of a Mac user 😉

  1. Thanks!!!!! it works on mac book pro with os 10.7.4 and an external HDD formatted ext.3 by a dreambox DM800HD. 

  2. Thanks for the tip! That worked for me (after I remembered to mount the disk with sudo) with a WD Passport USB disk and OSX 10.8.2. Appreciated….

  3. You are very welcome!

  4. Thank you!!! Been banging my head all day long on why it would work…

  5. wouldn’t*

  6. Glad it helped.

  7. Thank you good sir!  In case anyone is wondering this works with ext4 and Maverics 🙂

  8. Thanks for confirming 😉

  9. — Thanx for this information. Turned out to be helpful in resolving Mac OSX/Maverics (10.9…) NTFS mount issue. Had mucked around many hours diagnosing/researching largely to no avail. Re-installing OSXFUSE with the MacFUSE Compatibility Layer turned on finally did the trick.
    — Once successfully mounted, the error message: “Did not receive a signal within 15.000000 seconds. Exiting…” continues (as noted before with Mountain Lion/10.8…), which apparently can safely be ignored. Presuming the latter result of compatibility layer issues not yet resolved.

  10. — NTFS mount issued resolved as noted in my 2014.06.25 note, found to be very stable configuration and judged reliable in essentially daily use with primary NTFS working drive for personal information management (PIM) — all personal working files/data to keep as “Personal Portable Private Cloud” drive for working with various computers (desktops, laptops, …) & operating systems (including OSX, Linux, MS).
    — Although secondary error message continues, re: “Did not receive a signal within 15.000000 seconds. …” on every new mount of the NTFS drive continues; ignoring the warning so far has resulting in no noticeable negative consequences.
    — Operability continues after recent upgrade/update to OSX 10.10 Yosemite.

  11. THANK YOU!!!!

  12. Valeu cara, deu certo no meu!!!
    Agora ele aparece uma mensagem a dizer:
    NTFS-3G could not mount /dev/disk2s1 at/volumes/USB DISK because the following problem occurred:

    Did not receive a signal within 15.0000000 seconds

  13. I saw it also some times.
    As far as I understood it could happen with slow bus/external USB drives.
    In my experience it is harmless.
