The new option in Photo Mechanic to render RAW files using OS X is a welcome addition when trying to judge sharpness and only a small JPEG preview is embedded in the RAW file. Despite this advantage there are two major drawbacks to rendering the RAW data and not the embedded JPEG:
1) Rendering is much slower
2) Changes to the picture made by editors such as Nikon Capture are not shown when the RAW file is rendered by Mac OS X. They are shown when the JPEG is rendered because Nikon Capture embeds a preview with the edits applied.
While rendering the RAW file has some advantages, there are also significant drawbacks. Would you please consider adding an option to change whether the RAW is rendered or the JPEG is rendered in the preview window?? This will allow one to switch back and forth easily if necessary and get the best of both worlds depending on what is trying to be accomplished.
Thank you for considering my request.
