Yes, I will try to change from A to S (or M).
Aperture sees the camera (A700), but I can't "take" a picture from the computer – AND the camera is locked with the message "Setting up PC connection..." (or something).
Sony Remote works "one-way" as you describe it – but it is to prone to crash for me to like
I also did a test with a Automator script attached to the same folder I save the image in – and did a auto import into Aperture. Works – but a big minus is that if I want to filter out the last import session (handy!) it is just one, single image.
