Apple Seeds First OS X 10.10.1 Beta to Developers
Apple has just seeded the first beta of OS X 10.10.1 to developers. This version comes almost three weeks after the release of 10.10 to the public. With Yosemite many people have noticed an issue with Wi-Fi, which this version likely fixes. Apple is asking developers to focus their testing on Wi-Fi, Exchange accounts in Mail, and the Notification Center.
Developers can update to beta 1 in the Mac App Store > Updates > Software updates > OS X Seed 10.10.1. If you don’t have it yet you can download it for the first time from the Mac Developer Center.
