I came across a ECM archive that I need to extract.
The Unarchiver can't handle this format, and I'm not sure about other utilities.

How do I extract ECM in Mac OS X Lion?

You can use the ECM tools created by Neill Corlett, the creator of ECM. Just run "unecm" on the file.

There are binaries for Mac here

If that seems intimidating, there is a youtube walkthrough here that uses a GUI and contains links to the tools used.

+1 for command line tools. The video is down though – lajarre Oct 18 '12 at 0:18
Note that ecm is also available via HomeBrew. – Tim Visher May 12 '14 at 16:51
The binary link is broken, but Homebrew still works good! (thanks @TimVisher) – alanjds Aug 1 '14 at 14:39
