Apple has delivered developers their next beta of OS X 10.10.1, build 14B17.
The beta is available through both the Mac App Store and the Mac Developer Center. Focus points for testers are again WI-Fi, Exchange E-Mail Accounts and Notification Center. I can also confirm that public beta testers have also received the new build, as pictured in the above screenshot from my MacBook Air. OS X Yosemite was released to the public last month to positive reviews, with praise for its simpler new design and handy integration with iOS through it’s Handoff feature.
