Q: What's the latest on D600 .nef files

Apple has issued Digital Camera RAW Compatibility Update 4.01, adding support for 11 cameras to Aperture 3 and iPhoto '11. The update includes support for many of the latest cameras including the Nikon D600, Sony Cyber-shot DSC-RX100, Canon EOS-M and Panasonic G5. Many of the latest enthusiast compacts, including the Canon G15 and S110, and Panasonic DMC-LX7 are also covered, though there's still no support for recent high-end Fujifilm models.
