I work with Aperture 3.4.3, PhotoShop CS6, Photo Mechanic 5 on OSX 10.8.2 with NEF images from a Nikon D4.
My workflow is based on image rating and color labels, Aperture is used for cropping and other photo tasks. If I only want to sharpen I choose rating 3 stars and start my applescript. The script marks the 3 star images with a red label and export them to photoshop via a droplet. The final result is shown in Photo Mechanic. So far so good, but PM5 shows the chosen rating, but don't show the chosen color labels. The red label is called Sharpen inside PM5, Aperture en OSX and I also has the Synchronize Color Class with marked.
If I only mark a few images, with PM5, with the red color label they don't have this color label when I open the folder with finder.
Is there a setting for this?
