os_x_yosemite_round_iconApple today seeded a fifth beta of OS X Yosemite 10.10.2 to developers, just one week after seeding the fourth beta of OS X 10.10.2 and nearly two months after seeding the first beta.

The new beta, build 14C99d, is available through the Software Update mechanism in the Mac App Store and through the Mac Dev Center.

As with previous betas, Apple asks developers to focus testing on Wi-Fi, Mail, and VoiceOver. Many Yosemite users have had some ongoing problems with Wi-Fi since the new OS was first launched in October, and a November 10.10.1 update did not resolve all of the lingering issues.

Please tell me that a public release is imminent as I'm still on 10.10.0. I just don't want to update to 10.10.1 then have 10.10.2 come out the next day.

What's so wrong with updating again the next day?

Well, it's time for my bi-annual fresh OS install on this non-retina iMac.

Why are you reinstalling every 6 months? Are you doing something special to knacker the OS as it should not need reinstalling every 6 months

I often wonder just what it is about wireless connectivity that Apple struggles with. Bluetooth and WiFi seem to be among Apples weakest skills. You'd think after all these years they'd get tired of the repeated failures they've had.

Those of us who have been long time customers, especially with their laptops have had more than our fair share of bugs, annoyances and even rather long stints of down time. Apparently it will never be a priority.

They're doing something horrible with the whole networking stack, which includes bluetooth.

It looks like they've been trying to integrate it deeply to work with other features like AirDrop, Handoff, Continuity, and so on but when they go wrong, so does the entire stack.

Before AirDrop and other features, the network stack was stable as heck. I never had any issues for like a decade before they decided to do something fun.

DNS issues are pissing me off in Yosemite, they've replaced the stable and reliable mDNSresponder with craptastic buggy as heck discoveryd at the last minute. They replaced mDNSresponder late in Yosemite development, so I'm not surprised it's so unstable.

You can find out more about the DNS issue here: http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-you-can-do-to-fix-it/

I could not agree more. Either Apple needs to hire more internal developers for their OS development or they need to push back their release cycle.

Between iOS and OS X, I feel like I'm apart of a perpetual beta cycle. I prefer stability and usability over beta features that almost work.

Probably an old windows habit.
