Mail, graphics problems among focus areas
Apple has seeded the first OS X 10.9.1 beta to developers, reports say. In release notes, the company asks developers to concentrate testing on Mail, graphics drivers, and VoiceOver accessibility. The code is listed as build 13B27.
Work on v10.9.1 has been underway since before Mavericks shipped to the public. Apple is even believed to be developing v10.9.2 and v10.10, the latter under the codename "Syrah." Syrah should ship late next year, and is expected to adopt more still more design cues from iOS.
