That's really disappointing, especially as I have just spent US$135 upgrading From Helicon Focus Lite to the Pro X64 version purely for that reason! So far as I can see there is no warning on the website that there is less functionality in the Mac version than advertised. The website says simply that the Pro (and the X64 Pro) version includes a "Batch mode to process multiple image stacks or the same stack with different parameters"
My reason for wanting batch processing is that it often takes quite a bit of experimentation with different parameters to get the optimal results with macro images. Now that I have a fast Mac, I'd like to be able to queue several different parameter selections and leave the computer to crunch through them all without having to sit at the screen and do them one by one.
I do hope that you will be able to add this soon to the Mac version, especially as the Mac is really the computer of choice for much serious image-processing work.
