Hi Mac folks,
If you have ever tried to use a Mac version of Raw Therapee that is remotely modern, you may have been disappointed that it did not work as expected, or it crashed before it even started. For those of you who didn't give up, you may have reverted to the older, v3, or tried compiling from source (i actually got v4 to compile, which I could not believe, honestly). All for the love of trying new applications, and workflow - unless you are not such a photonerd as I am.
Well, your patience has been rewarded, so to speak. I have been following the compilations on the Japanese blog "Mattintosh Note" and the blogger there knows what s/he is doing and has made their compilations of RT available - the most recent I note finally works for me. I was having color management problems with RT output with any compilation I could find or make myself and, I am happy to say, the RTMX (Raw Therapee for Mac OS with X11) compilation works as advertised. It also supports OpenMP and is 64bit. Read about it and download here:

You may need to cut and paste this link into Google translate or similar to read the specifics, as there are some installation instructions you need to be aware of. I repeat, read the directions. Here is a google translate link to English:

It's not official, but it works really well. I am running it on my MacBook Pro under 10.7.5.
Now you get to play with all of the bells and whistles like the PC and Linux users. 
Enjoy - if it works for you and you use it, leave Mattintosh a comment at the bottom of the blog page.
