I'm trying to mount an Ext3 external USB hard drive in OS X 10.7.4. I installed OSXFUSE (with macfuse compability layer), which worked fine. After that I tried to install EXT2FS but the install processs always aborted.

Any ideas?

Have a look at this open source project: fuse-ext2. This link:


explains how to configure fuse-ext2 and OSXFuse on OS X 10.7 "Lion" to get access to ext3-formatted drives.

(The project is tagged beta and inactive since 1 year (last commit on Aug 15 2011), but according to the link above it is compatible with "Lion". You only will get read-only access, read/write is not ready for prime time...)

Another possibility, as linked by kopischke in his comment, is a commercial solution called Paragon’s ExtFS driver. It's not clear from the feature list whether ExtFS driver works on OS X 10.7 "Lion", so if you decide to go this way be sure to find out before purchasing it.

Other projects, like Ext2 for Mac OS X or ext2 filesystem in user space are either tagged inactive or alpha.
