OS X Mountain Lion Developer Beta Downloads

[sparkyscott21]

Apple has released OS X Mountain Lion Developer Preview 3 to those registered with the Mac Developer program. The new build comes as 12A178q and includes many bug fixes, though it still includes a fairly lengthy list of known issues and bugs. This is the third beta release of OS X Mountain Lion, which currently has a rough public release date of “Summer” .

Developers can download OS X Mountain Lion DP3 from the App Store, though logging in through the developer center is necessary in order to receive a redemption code.

Due to stability issues and future upgrade problems, Mountain Lion Developer Preview should not be the primary operating system on a Mac. Follow a guide to set up a dual boot system between OS X 10.8 Beta and the more stable OS X 10.7 build for best results.

update

Just a heads up for those of you who can download this....

I have just d/l this, and, there are several things that MAY not work right after it is downloaded...

Just read the seed note, and go from there... Ya might wanna think twice before hand if you don't have your H.D. partioned for both...

Thought I would let you know ahead, since I see some issues on mine....

Apple has issued a software update via the Mac App Store to Mountain Lion Developer Preview 4, originally released last week.





This update is the second time Apple has updated the Mountain Lion Developer Preview via the Mac App Store rather than releasing an entirely new DP -- Apple issued a similar update in May.

Apple did not specify changes in the update, saying only that it "is recommended for all users running OS X Mountain Lion Developer Preview 4. With Mountain Lion's final release expected next month, Apple should be moving towards a final build soon.

On a random note, the Dock in OS X 10.8 DP4 got a slight UI update and looks quite nice as shown in this screenshot.

Build number is 12A248 (First version of Preview 4 was 12A239)

The release notes, which indicate that the number of bugs is decreasing and Game Center is getting close to being in full working order. It's not yet known whether or not all of the new Mountain Lion features showcased today are included in this build, but Facebook integration at least can be enabled with a separate download. If they're not, they certainly ought to be in the next one: Apple has committed itself to a July launch of the new OS. Once released.

The update weighs in at 1.08GB.

Apple has issued a new update for Mountain Lion Developer Preview 4 via the Mac App Store. It was first noticed by Twitter user @Lhunar and introduces the new Mountain Lion Security Update system.

The new system does daily checks for security updates as Apple ramps up its security protocols in the next-generation operating system. Earlier this month, it was noticed that Apple had changed the language on its OS X marketing pages following the Flashback malware attack earlier this year.

The new security system in Mountain Lion -- including Gatekeeper and other features -- appears to be a significant expansion of the XProtect system that Apple has used in the past to try to thwart OS X malware.

The update weighs in at 1.16GB and is available to developers with Mountain Lion DP4 installed via the Mac App Store.

The Golden Master seed of OS X Mountain Lion has been released to developers. Golden Master (GM) builds are typically the release version of software, indicating that a public version will arrive very soon. The GM build is 12A269 for Client and 12S302 for Server.

Registered developers can get a download code for Mountain Lion GM directly from Apple’s Dev Center, that code can be redeemed through the Mac App Store as usual. Developers can also download a new version of Xcode 4.4 development suite.

OS X Mountain Lion is versioned as Mac OS X 10.8, and includes over 200 new features, many of which are borrowed from iOS, including iMessage, Notification Center, Share Sheets, Game Center, Notes, Reminders, Dictation, and significantly enhanced iCloud integration.

Apple previously stated that OS X Mountain Lion would be released this July at a price of $19.99. Anyone who meets the system requirements will be able to update to Mac OS X 10.8 from Lion or even from Snow Leopard.

"200 New Features" Mountain Lion slide shown at WWDC

Apple released the Golden Master (GM) version of OS X Mountain Lion to developers today. The "golden master" designation indicates that this version of the software is intended to be the final version released to the public, barring any last-minute issues. The Build is 12A269.

Apple first previewed Mountain Lion in February, highlighting many features already present in iOS, including Messages, Reminders, Notes, Notification Center, Game Center and more at that time. At WWDC, Apple announced additional features, including Dictation, iCloud Tabs, and 'Power Nap'.

We previously highlighted this video which shows off many of the new features found in Mountain Lion:

Mountain Lion will be priced at $19.99 and released to the Mac App Store in July.

In an email sent out today, Apple has begun to push OS X developers to submit their Mountain Lion ready applications to the Mac App Store. This email follows the release today of the OS X Mountain Lion GM build to developers.


According to Apple:

Make sure your apps take advantage of the great new features in OS X Mountain Lion when the world’s most advanced operating system ships to millions of customers worldwide. Download OS X Mountain Lion GM seed and Xcode 4.4 GM seed, now available on the Mac Dev Center. Build your apps with these latest seeds, then test and submit for review. You can also submit iOS apps that take advantage of the new cross-platform Game Center Groups, so they’ll be available when OS X Mountain Lion ships.

Apple wants to make sure that developers have their Mountain Lion applications submitted as soon as possible, since Mountain Lion is due to ship to customers sometime in July for $19.99

If your Mac wasn’t made in the last year and a half, you won’t be able to do this.

With OS X Mountain Lion, AirPlay Mirroring is finally coming to the Mac, allowing some Macs to stream audio and video directly to their Apple TV.

‘Some’ is the operative word here. Much to the disappointment of the vast majority of Mac owners who will be installing Mountain Lion on their machines in a couple weeks time, AirPlay Mirroring will only work if you have an iMac, MacBook Air or Mac Mini from mid-2011, or a MacBook Pro from early 2011.

There’s been a lot of conspiracy theories floated about this requirement. Some have argued that it’s forced obsolescence on Apple’s part, trying to force older Mac owners to upgrade their machines. Others have suggested that the reason Apple requires a Mac from 2011 or later is because of special DRM technology in Intel’s chips that didn’t debut until last year.

The truth of the matter, however, is far less sensational. The reason you need a 2011 Mac to make use of AirPlay Mirroring in OS X Mountain Lion is because the graphics in older Macs just don’t cut the mustard.

Following on from the recent release of OS X Mountain Lion, there were quite a few reports around the web, and in particular in Apple’s official support forums, saying that battery life appeared to be greatly compromised for MacBook Pro and MacBook Air owners who had upgraded to the newest OS X release. AppleInsider was the first website to report on the issue, and now today it is reporting that according to Softpedia, the issue seems to have been resolved, as indeed Apple promised that it would be, in the pre-release beta of OS X 10.8.1. The information comes courtesy of an anonymous developer, who has installed the beta and has told Softpedia that the battery life on his MacBook has increased from 4 hours and 5 minutes when fully charged, to more than 8 hours. I think that is what we call a result! No word as yet as to when this update will be released to the public, but at least we know that an effective fix is on the way.
