Just got the new MacBook Air 13" with an SD slot. As a photographer I want to start up Lightroom not iPhoto when the card is inserted. How do I set that? RESOLVED: Just after posting I found another thread (http://forums.macrumors.com/showthread.php?t=302928) with this answer (thank you laurencenoton): Go to Applications -> Image Capture. Then select preferences -> general. Change "When a camera is connected, open:" to Lightroom, or like me Aperture! Hope this helps.
