Apple seeds first OS X 10.10.1 Yosemite beta to developers

Mail OS X Yosemite

Apple has seeded the first beta of OS X 10.10.1 Yosemite this evening. The update, labeled build 14B17, is available through the Update tab in the Mac App Store and the Mac Dev Center for all registered developers.

Today’s release comes nearly three weeks after Apple officially launched OS X Yosemite to the public, which brought about a number of improvements, including a redesigned UI, text message forwarding and more.


We’re not sure yet what changes 10.10.1 brings, but there are a number of bugs that need fixing. We’re currently installing the beta, and will note any major changes. Feel free to e-mail us at
