I downloaded and am attempting to install but it just keeps crashing.
Luminance HDR 2.3.1 works with Mac OS X 10.8+
Thanks, I'm an idiot lol. I clicked on the first download I saw (2.3.1) which needs Mac 10.8. I only have 10.6 but finally saw somewhere 2.3 which installed just fine.
Now if I can just make it accessible through LR3 in the top pull down menu like my other programs (PS, DxO, Perfect Effects, etc.) then all will be good in the world :)
