New from Apple is Digital Camera RAW Compatibility Update 3.9, which adds compatibility with several new cameras to Aperture 3 and iPhoto ’11. The newly supported cameras include the Canon PowerShot S100; Nikon 1 J1, 1 V1, and Coolpix P7100; Olympus PEN E-PL1, PEN E-PL3, and PEN E-PM1; Panasonic Lumix DMC-FZ150; and Sony Alpha NEX-5N, Alpha SLT-A65, and Alpha SLT-A77. The update applies to both Mac OS X 10.7 Lion and 10.6 Snow Leopard; Apple publishes a full list of supported raw image formats in both Lion and Snow Leopard — interestingly, the Lion list is a bit longer.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
