RAW update makes minor tweaks
In the wake of OS X Mavericks' release, Apple has already posted three related software updates. The first is Digital Camera RAW Compatibility Update 4.09. The code adds iPhoto '11 and Aperture 3 support for Olympus' PEN E-P5 camera, and brings back lens correction for Sony RX100 photos. It also solves bad white balance for Nikon images edited by third-party apps.
For people who have yet to upgrade to Mavericks, Apple has issued Lion and Snow Leopard Migration Assistant Updates. In both cases, the software is meant to smooth out the upgrade process. Apple hasn't issued any more details.
