Since upgrading to El Capitane I notice I can't delete items from my SD cards or memory sticks which mean I can only delete photos etc by placing the card back in the camera. The SD cards are not protected. Also when I used to insert the camera SD card Aperture would automatically open...doesn't happen any more and when I want to import photos from the SD card Aperture doesn't recognise it so I have to place the photos in a folder and import them from my desktop. I'm guessing I need to change a preference somewhere but can't find it?
Have changed Aperture preferences but still tries to open iphoto instead. Hope someone can help
