Apple's Mountain Lion Developer Preview was updated to version 12A193i (from 12A178q) weighing 1.45GB.
"With the Developer Preview, you can explore Game Center, Notification Center, Documents in the Cloud, new sharing capabilities, advanced security features, and much more"
Apple Mac OS X 10.8 Mountain Lion includes lots of features from iOS, such as Reminders, Messages and Game Center. One noted update from the previous version of the Developer Preview is a Do Not Disturb setting to Mountain Lion's Notifications Center, as outlined by 9to5mac, which allows users to block incoming alerts and banners.
Furthermore Mac OSX 10.7.4 Lion Update is around the corner: 11E53 is the current build that was seeded to developers. The previous release was numbered 11E52 - so a final public update is imminent. Apple notes that there are no known issues with this build but asks developers to focus their testing on graphics, iCal, Mail, Printing, and Time Machine.
If there are updated kexts is not known at the time of writing - it looks like we have to wait for the final release of 10.8 ML to get new graphics drivers, such as support for the 7xxx AMD Radeon GPUs with the Codenames Cedar, Caicos, Turks, Cape Verde, Pitcairn, Tahiti and New Zealand.
Besides running hackintosh on Intel Sandy Bridge-E, there are more good news from the front:
Chimera, the bootloader that powers standard PC hardware to boot up Mac OS X, received an update allowing it to support OS X Mountain Lion. To obtain OS X Mountain Lion you need an Apple Developer Account that'll cost you $99 per year, but of course your might already know where to find Mac OSX 10.8 Mountain Lion by yourself.
Today MacMan updated Chimera to version 1.8. For Mac OS X developers, OS X 10.8 Mountain Lion support has been added. This version will be included in the next MultiBeast release. (via tonymacx86)
[Update] Intel Socket 2011 does not only support Sandy Bridge-E, but also the upcoming Ivy Bridge-E Chipset, as outlined by one of our commenters. That makes the Socket-2011 Mainboards a perfect choice for a hackintosh system.
Many of us are waiting for an update to the Sandy Bridge (E) Chipset to the upcoming Intel Ivy Bridge (along with the release of new Apple Hardware), that would allow running the new Intel Chipset with Hackintoshed customac systems.
But what about Sandy Bridge-E?
Ivy Bridge will be Quad-Core. If you want more threads and cores, go for SB-E. Sandy Bridge-E as well as Ivy Bridge will have PCIe 3.0. SB-E has 40 PCIe lanes (compared to 16 lanes in Sandy Bridge) as well as 1600MHz memory speed (quad-channel memory) which should be around 33% faster in theory.
There are confirmed builds that can run Mac OSX 10.7 (Lion) as well as 10.6 (Snow Leopard) with the Intel Sandy Bridge-E (SB-E) X79 Chipset. Integrated Graphics are not supported, but who needs them anyway, since the AMD 6990 GPU or the upcoming 7990
Here is a list of the confirmed mainboards:
Pro: good build quality (compared to other versions of that board)
Cons: none. The Asus Rampage IV has even better build quality.
Pro: Awesome board! (nanofunk recommendation). Gigabyte has a longer history of hackintosh-capable boards, so get one of those.
Cons: none, really. Overclocking features could be better.
Pro: awesome build quality, extreme overclocking support.
The MSI X79 Big Bang XPower II is suspected to work as well (once it becomes available). Theoretically, most of the X79 boards should work, we just have to wait and see what early birds (early adopters) are coming up with. Keep up the great work, ppl! (and don't forget to share your experiences in the comments below)
The new ATI Graphics Cards from the 7970 series are super-fast, while being single GPU systems (the upcoming 7990 will be a dual-GPU 6GB Graphics Card). Besides being quite "cheap" (around 500€ in Europe, $589 in the US, they are said to be supported in OSX soon (see also a discovery by netkas) - until then, there is a current way how to use them (although not accelerated) with chimera. Props go to Shrapnl from the tonymac86 forum:
I was able to force my 7970 into a higher res (still unaccelerated of course) via the org.chameleon.boot.plist with the following:
Of course, you can overclock the 7900 Series just fine. There are "Waterblocks" from Aquacomputer for the 7900 series, as outlined by Geeks3D.
Of course, the GPU runs quite fast without overclocking, still you could go faster. Below: Shamino has overclocked a Radeon HD 7970 under LN2 with the following clock speeds: 1650MHz for the GPU and 1800MHz real speed (7200MHz effective) for the memory. (Source: geeks3d)
[Update] the best way to cool your AMD Radeon 7970 is the Arctic Cooling Accelero Xtreme 7970 which will cool down your GPU for additional 10degrees celsius (at least). Overclocking, here we go!
Since I had this problem several times when installing Mac OSX Lion 10.7.2, here is the simple solution: remove any RAM over 4GB. Keeping only 4GB RAM in the Mac (in my case a MacBook Pro) made the installer run flawlessly. It's as simple as that.
