Apple has seeded a new beta of OS X 10.8.1 to developers, exactly a week after the first build came out, according to 9to5Mac.

The release has a build number of 12B17 and Apple reports no known issues, but asks developers to focus on a wide variety of areas for their testing. The delta update -- where only items that have changed are downloaded -- weighs in at 43.27MB.

According to 9to5Mac, developers have been asked to test Active Directory, Microsoft Exchange in Mail, PAC proxies in Safari, SMB, USB, and Wi-Fi and audio when connected to the Apple Thunderbolt display -- the same list of items as the prior release.

The OS X 10.8.1 seed is available for download via the OS X Developer portal at developer.apple.com.

No, I haven't installed it - but I have been following the various reports of hard crashes, absurdly short battery life and iOS-like oddities. And it doesn't seem that great to me.

So whining about something you've never even tried. Thanks, that's useful.

There are always problems with any release of any software, OS or otherwise, so anyone could declare any release a "train wreck" if the only basis for that is some people reporting problems online.

What really matters is how widespread problems are and how severe they are. Problems are to be expected for any .0 release, and for a .0 release it's surprisingly solid (heck of a lot better than 10.7.0, and I suspect better than 10.7.4 for most people).

It's just common knowledge, anyone doing mission critical work or otherwise sensitive to issues should skip all .0 releases (and often one or two after that). And those that do need not regale us with whining about problems they've just heard about, that adds nothing to the discussion.

Possible release next week since there are no known issues.

All things considered Mountain Lion has been pretty much problem free for a 10.x.0 release.

Then please, read every post in this thread:

https://discussions.apple.com/thread/4135250?start=0&tstart=0

and then report back :P

Install the OS and see for yourself if it really is that terrible instead of complaining for the sake of complaining.

As it stands you're just whining and whining...and its quite annoying to read in every other thread one comes across.

And people CONTINUE to spout the same nonsense about the purported advantages of a "clean install" - for every five positive reports, I can show you five OTHER reports in these forums from users who have the same if not worse problems AFTER a clean install.

So let's stop with this placebo recipe, shall we?[COLOR="#808080"]

I did a clean install. It worked for ME, perhaps it will not work for YOU or OTHER people but it worked for ME. A clean install of a new OS is never a bad thing to get rid of left over files here and there.

It's not the end all be all solution to anything, but it can be beneficial. I know you do not think so but so far as I can tell you don't like much of anything.
