I have yet to test this, but before rating it, I have to say I'm gratified to see this out in an OSX version... I've been using the Classic version to decode stubborn MIME-variety files for some years now, with at least a 90% or so success rate (YA-Converter often would open the others, usually part of a multi-file set), and from what I can see, there was no comparable program on the OSX platform so I'm very happy to stumble upon this one. (I had actually been taking stubborn files to my Classic machine, decoding them there with Decoder 2, and then transfering them back!) Hopefully this version will be as effective as Ye Olde Classic one was...
