OS X 10.9.2 build distributed to developers, with focus on Mail issues
On Thursday, Apple seeded a new build of the forthcoming OS X 10.9.2 update to developers, a month after the first one. The new build, 13C39, continues to focus on issues within Mail, as well as VPN functions, Messages, graphic drivers and VoiceOver. The revamped Mail introduced in Mavericks has had a number of issues with Gmail compatibility and problems with Smart Mailboxes, along with other more minor issues. The update is available through Software Update or Apple's developer portal (registered developer account required).
Digital Camera Raw update adds Canon EOS M2, fixes bugs
Also on Thursday, Apple updated its Digital Camera Raw Compatibility plug-in for iPhoto and Aperture. Version 5.03 adds compatibility for a single camera model -- the Canon EOS M2 -- but also resolves a pair of bugs affecting other cameras. It resolves a problem that prevented lens correction with Sony Cyber-shot DSC-RX100 images, and fixes a color cast issue on some Olypus OM-D E-M1 images. It can be downloaded from the link above on Apple's support website, and requires OS X 10.8.5 or later.
