From the developer:
Photivo is a free and open source (GPL3) photo processor. It handles your RAW files as well as your bitmap files (TIFF, JPEG, BMP, PNG and many more) in a non-destructive 16 bit processing pipe with gimp workflow integration and batch mode.
Photivo tries to provide the best algorithms available; even if this implies some redundancy.
You may want to check out more software for Mac, such as ImageBuddy, Downsize or particleIllusion, which might be similar to photivo.
