Apple's fifth beta of OS X Yosemite 10.10.2 continues focus on WiFi, Mail & Bluetooth

The new beta clocks in as build number 14C106a. As usual, Apple warns developers that they will not be able to revert back to previous builds after installing the update.

The continued focus on Wi-Fi underscores the issues that have plagued users of Apple's desktop operating system since its release in October. Among the problems cited by users are dropped connections, protracted connection periods that often result in timeouts, and poor throughput.

Mail also remains a problem, though the most glaring issues have largely been addressed in previous maintenance releases. There is no word on exactly what issues Apple is addressing with Bluetooth or VoiceOver, its navigational aid for visually-impaired users.

OS X Yosemite 10.10.2 beta 5 is available as a delta update via the Mac App Store or as a package download from Apple's developer portal.
