I want to upload RAW files from my SD card to my Mac. My computer can't read it, and I know I need the ACR(adobe camera raw) plug-in so it can. Where would I find that? Did it come with my Photoshop Elements 10 CD when I installed it or do I go somewhere to download it? Thanks!
Whether OS X can create a preview image of the files or not, the computer should see them. If OS X can't read your card, there's no way to get the data into PSE for ACR to work on. Try using a different card reader.
