If you use OS X I suggest you rely on the homebrew project. That ext4fuse is read-only also means that it's completely safe to use. Most of them I lack, so it's a long shot.
Write support will only come if I get the time, knowledge, patience and nerve Some point and I've heard that OpenSolaris should also work. The main reason thisĮxists is to be able to read linux partitions from OSX. This is a read-only implementation of ext4 for FUSE.
