Apple today seeded build 14B23 of OS X 10.10.1 to developers, one week after seeding the first OS X 10.10.1 beta, build 14B17, and nearly a month after first releasing OS X Yosemite to the public.

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

yosemite10101betaupdate
While it is unclear what improvements the first update to OS X Yosemite will bring, there are several bugs in the operating system including a major Wi-Fi issue that has caused connection problems for a number of users.

Apple is asking developers to focus on Wi-Fi, Exchange accounts in Mail, and the Notification Center.

Typo in the title?

You mean Yosemite?

mavericks

Mavericks 10.10.1…

mavericks? some one is feeling nostalgic.

Doesn't the title needs to be Yosemite instead of Maverick?
Edit: hey, I'm not the first!!!

Check title...

Yes, I most certainly meant to write Yosemite, not Mavericks. Very sorry about the error, it's been fixed. Total brain fart when writing the title there.

This design update came with 10.10.1 beta 1

It's not a part of the update. The MAS is web-based, so Apple can push it whenever it wants. I have it in 10.10.

Well done Macrumors. You fixed the title so quickly that notification centre showed the correct title.

I've used every Mac OS version going back to Mac OS 7.1.
With that said, this is the buggiest Mac OS General Master release EVER!

THE IPHONE CONNECT BLUETOOTH OF DEATH BUG ALONE!

You spend $5000 on a Mac Pro and can't connect an iPhone 5s?

ARE YOU KIDDING ME APPLE?

I still can't believe that the Feedback Assistant program itself DISABLES WIFI ROUTERS!

ARE YOU KIDDING ME APPLE??

And then there's empty BLANK BOOT SCREEN OF DEATH because you didn't turn your TV on in time.

ARE YOU KIDDING ME APPLE???

Trust me. Don't believe the Apple Fanboys. They're a cult of favorable press, not real.

You do realize that you're just one of what is essentially a handful of people having the exact problems you're having? Even if you find 100, 500 or 1000 people on a forum like this saying they have the same problems, it's still just a drop in the bucket when looking at the big picture.

That's not me being a fanboy, just stating the facts. Not everyone has problems and not all problems are the same across all products. I should know as I was having Mac Mail issues with Yosemite (starting with one of the later DP builds) that only a handful of people were having, yet Apple techs were trying to isolate and fix the issue. Sometimes sh;t happens where a particular setting screws something else up and it takes time to figure it out. This is true in computers, cars, houses and frankly, life.
