Lightroom 4 is the last version that supported 10.6.8. You would have to find a vendor that still has it for sale. Although I think Apple quality control has went down hill Yosemite is working great for me. I may upgrade to El Capitan in the near future. I always do fresh (format-new install) installs of the OS so that prevents a lot of problems. I would highly recommend upgrading and buying Lr6 or even better go with the CC version and getting all the new tools not available in the standalone and also getting Photoshop.

even if it is an older version that is fine.
Which camera will you be using? It might not be supported by Lr 4...
Good catch Keith. If the camera is very new even the DNG converter has a minimum requirement of OS X 10.7
