Read/Write ext2 ext3 ext4 on Mac OsX with fuse-ext2

you need the following installed to be able to compile:

Apple X Code + Apple X Code Command Line Tools (you find a download on the Apple Developers Website) + OSX Fuse https://osxfuse.github.io/ (former Fuse for OSX)

go to website https://github.com/alperakcan/fuse-ext2 and follow the instructions (copied below).

open terminal window and type

cd /tmp

sudo mkdir ext4

cd ext4

sudo nano script.sh

copy the following text to script.sh - [see below] (copied from github/alperakan), save+close with apple+x - yes - enter

sudo chmod +x script.sh (makes the file executable)

./script.sh (execute the file)

after the script has been executed test the fuse-ext2 function by typing

cd ~

dd if=/dev/zero of=fs.ext2 bs=1024 count=102400 (creates empty virt.disk)

/opt/gnu/sbin/mkfs.ext4 fs.ext2 (creates the ext4-filesystem)

fuse-ext2 fs.ext2 /Volumes/fs.ext2 -o debug,rw+ (mounts the disk in Finder)

if you get error messages try commands with sudo

if you have an already ext4 formatted harddrive/usb you can mount it by

plug in the hdd and click ignore if osx tells you to initialize or eject the disk
go to the terminal and type

df -h (won't show a extFs-Disk :-( )

but you will see one additional drive by typing

ls -l /dev/disk*

if you have doubts which disk is the extFs-Disk you can also type

diskutil list (in my case /dev/disk2s1)

to mount it in read-only with debugging messages in terminal type
sudo fuse-ext2 /dev/disk2s1 /Volumes/fs.ext4 -o debug,ro

to mount it in read-write-execute with debugging messages in terminal type
sudo fuse-ext2 /dev/disk2s1 /Volumes/fs.ext4 -o debug,rw+

it is also possible to share the hdd but i did not find a way to enable time-machine-ing through afp with a extFS-hdd.
