Just over a couple of weeks after Apple released the first beta of Mac OS X Yosemite for developers since the official release, the company has come out with a second beta. It isn't yet clear whether the 10.10.2 update fixes the Wi-Fi problems that have been plaguing users for some time now.
Ever since Yosemite made its debut last month, users have reported various issues. Chief among them is that after installing the OS their Wi-Fi becomes extremely slow or unstable, dropping every few minutes.
The 10.10.1 beta claimed to enhance Wi-Fi reliability, among other improvements, and yielded a formal OS update released to the public last week. But it failed to fix the Wi-Fi problems and users continued to post complaints in Apple discussion forums, third-party sites, and other platforms.
As of writing, the longest running thread on the Apple Support site about the problem, which is titled "OSX Yosemite Wifi issues", has 1,368 replies, and has been viewed 278670 times.
While announcing the availability of the OS, the Cupertino-based company had said, "OS X Yosemite is the most advanced version of OS X we’ve ever built," adding that it ushers in the future of computing, where your Apple devices all work together "seamlessly and magically." Apple is yet to issue a formal statement on what might be causing the Wi-Fi issues.
