OS X 10.10.1 Update Seed 1 Released to Developers
Apple has released the first build of OS X 10.10.1 to those registered with the Mac Developer program. Labeled as “Pre-release OS X Update Seed 10.10.1”, the build is 14B17 and is currently available to developers, as well as those signed up to be participating in the OS X Yosemite Public Beta program.
The OS X 10.10.1 seed 1 release focus areas are said to be Wi-Fi, Exchange accounts in Mail app, and Notification Center. No specific bugs or issues are mentioned, but this release could be aimed at resolving some of the wi-fi issues that have impacted some Yosemite users, and perhaps could remedy the SMTP trouble with Mail app as well.
Mac Developers and those in the Public Beta can download the update through the App Store, accessible from the Apple menu. Note that automatic OS X system updates do not apply to Developer and Beta releases, thus the update must be installed manually.
Separately, Apple also released iOS 8.1.1 Beta 1 today for those registered in the iOS Developer Program.
There is no stated public release timeline for OS X 10.10.1, but typically OS builds go through multiple developer releases before being released to the wider public.
