nVidia Geforce GTX Titan GK110 works on Hackintosh with Mac OSX 10.8.4 and official Drivers, including CUDA support!
This is big news from the hackintosh front: since you are limited to using single GPU graphic cards on hackintosh (Mac OS X only supports single GPU systems) the best possible card up to now was the Geforce GTX 680 (see our previous article).
Not anymore, since the Nvidia Geforce GTX Titan (GK110 chipset) is working on OSX 10.8.4 with official Nvidia drivers. There are already some awesome hackintosh case mods and builds out there.
Netkas reported the card working on April 2nd. Furthermore, there is a possible ROM-hack to get the card working on Mac Pro machines, making it the fastest video card you can possibly put into your Apple Mac Pro.
The current discussions and experiences from the hackintosh community are promising, though we might see several driver updates in the coming weeks. CUDA is supported, also OpenCL is reported working, though strangely not with all different vendor models.
If you want to stay on the bleeding edge, here are recommended cards that people reported working with hackintosh:
If you want to be on the safe side, get the EVGA GeForce GTX 680 2048MB GDDR5, DVI, DVI-D, HDMI, DisplayPort, 4-way SLI Ready Graphics Card Graphics Cards 02G-P4-2680-KR which is working flawlessly and costs only half of the current Titan price...
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.
Apple's Store Page is currently "down for maintenance". While this often means new products are about to be introduced, it could also only mean a general site maintenance or redesign.
New MacBook Pros as well as new Mac Pros are on the horizon, including the possibility of the upcoming iPhone 5. Personally, I would favor a new Mac Pro line the most - giving us updated GPU drivers (kexts) as well as more hardware support. Let's see what the day brings.
[Update 2012-04-11 9:35 CET] Site is back online and NOTHING NEW. Apple really teases us too much these days. As if there were nothing to update. Still waiting for decent GPU support on the outdated Mac Pros.
New Apple Macbook Pro Models are on the horizon? Intel Ivy Bridge for the 13, 15, 17 inch and MacBook Air models are most likely, with quad core and possibly USB3 ports. There might be a "slim form factor" that would mean MacBook Air-like MacBook Pro Models, with USB3 ports along other features such as dual Thunderbolt ports and Retina Displays (treat this information as rumors!). As macrumors notes, Reseller Shortages Hint at Forthcoming Update for 15-Inch MacBook Pro: "Apple has been said to be ramping up production of new 15-inch MacBook Pro models carrying a thinner form factor, with Intel's rumored April 29 debut of quad-core mobile Ivy Bridge processors undoubtedly driving that timeline."
The 13" MBP still goes for around $1,115.00, the 15" Quad Core i7 15-inch version is still at $1,679.88. Prices for the upcoming models are obviously not known yet.
Think Different: How to Build Your Own Hackintosh eBook for $1 on Amazon shows how to build a customac
A new eBook on amazon describes in detail how to build and configure your hackintosh: Think Different: How to Build Your Own Hackintosh. Another book, the Ultimate Guide: Making Hackintosh sells for $4, but actually features almost the same content.
Here is direct link to "LOOK INSIDE" where some of the book contents can be read for free.
Want to try out the Mac operating system, but don't want to purchase Apple hardware? Check out "Think Different: How to Build Your Own Hackintosh", the latest guide from MakeUseOf. By author Stefan Neagu, this guide outlines what you need to do in order to build a Hackintosh. Whether you want to try using a computer you already have or buy a pre-built computer for the job, this guide shows you the way.
I just confirmed that 16GB RAM modules will work in the early 2011 Macbook Pro Models - and in the other Sandy Bridge Models as well, including
* Macbook Pro Early 2011 (13", 15", 17")
* Macbook Pro Late 2011 (13", 15", 17")
Theoretically, other RAM Modules with the same specs should work as well, but I can definitely suggest and confirm the Corsair Modules to work, as they show "Mac Memory" on the German Amazon page and reviewers are reporting successful installs.
Please tell us in the comments section if other RAM modules worked for you. 16GB is currently the largest supported Memory Upgrade for the Unibody Macbook Pro. OWC still sells the same KIT for $239.99.
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)
DigiTimes reports that Intel has notified partners that the company will "fully release" its Thunderbolt technology (previously known as "Lightpeak") in April 2012. Intel is reportedly preparing to launch Thunderbolt-supported motherboards, notebooks and desktop PCs at that time, other mainboard suppliers such as Gigabyte and Asus will follow.
Intel and Apple originally partnered on the new technology which has become standard across Apple's MacBook Pro, MacBook Air, Mac mini, and iMac. Digitimes reports that the cost of Thunderbolt technology is expected to drop in the second half of 2012, allowing more widespread adoption. While this sure is great for Windows users, that also means Thunderbolt will be available for hackintosh users!
While Apple does offer Thunderbolt across most of its product line, the first Thunderbolt products have been limited to relatively high end devices, such as the Blackmagic Ultrastudio 3D, the Magma Expressbox 3T or the Promise Pegasus Thunderbolt RAID. More widespread adoption should help drive adoption by accessory makers that will benefit both Mac and PC users that use the Thunderbolt technology.
Thunderbolt is not competing against USB3 (Intel said they see both USB 3.0 and Thunderbolt as complementary technologies) - furthermore there will be USB3 support for Apple devices, since there will be breakout boxes that offer USB3 connectivity.
According to the report, workers at several iPad component suppliers as well as manufacturing partner Foxconn will have limited time off during the usual Lunar New Year holiday. The Lunar New Year holiday itself falls on January 23rd next year, with workers generally receiving a number of other days off from work around that date.
Sources have been reporting a variety of rumored dates for an iPad 3 introduction, with some claiming a debut in the March-April timeframe while others have pointed to a February launch being in the works.
Apple last year launched new MacBook Pro models on Jobs' birthday, although that unusual Thursday introduction was likely a convenient coincidence driven by the debut taking place during the Presidents Day holiday week.

Since I had to reinstall my MacBook Pro after an SSD Drive fail, I stumbled upon a list I made, containing software essentials and basic application that everyone needs when reinstalling the OS. I compiled an up to date list: which applications are the essential apps in 2011/2012 when reinstalling Mac OS X.
This handy little app is a free un-packer, replacing Archive Utility that comes with Mac OSX. The Uninstaller does not only support .sit and .zip files, but also .rar, .7z and many other archive formats. This app is essential when working with archives and downloads.
A replacement for Quicktime and also for VLC. It has a nicer interface than VLC and supports the same file types (codecs) that quicktime does not: .h264, DivX, XVid, MVK, etc. mPlayerX recently became my favorite Media Player.
An awesome Mail.app replacement with great interface and actually improving the mail reading-experience: Sparrow has many features, such as perfect GMail integration, multiple accounts, avatar syncing from facebook, and many more. Recommended!
The best To-Do application out there. Best of all: Wunderlist is not only free, but it also synchronizes automatically via the web and your ToDo-Lists are available via web-interface as well as on any operating system (iOs, Android, Windows, etc.)
Best way to keep your Mac de-cluttered at all times: Clean My Mac from MacPaw deletes cache files as well as leftovers (junk from previously installed apps, etc.), Language files and so on. A perfect tool to keep the OS snappy at all times.
VoodooPad (former VoodooPad Pro) is an awesome offline desktop Wiki. I am using VoodooPad to store and interlink my ideas, texts and written content. It can hold RTF data: text as well as files from your hard disk can be directly linked. Images can be embedded or referenced. Highly recommended!
Apple Xcode is a free download via the appstore. It is not only needed for creating iOS and Mac OS Applications, but also to compile unix applications and to get other developer applications, such as Quartz Composer installed on your system.
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.
(via macrumors) Business Insider now reports that it has received word from a source who has claimed to have had access to an iPhone 5 prototype and offered some details on the device. We've been told this by an industry source who has been right about future Apple products in the past.
It has not been verified yet, but there are some leaked details, which are of course just rumors:
- 4-inch screen
- Aluminum back
- Capacitive home button
- "Flatter" form factor
- Much faster than current hardware, but poor battery life
- 10-megapixel rear camera
- Siri prototype known as "Assistant", which had been the rumored name for the feature until its introduction
Tonymacx86 showed how to Install OS X 10.7 Lion on any Supported Intel Core 2 or Core i based PC with xMove + MultiBeast. Furthermore, there is a Mac OSX Lion v10.7.2-HOTiSO that should also boot from any PC. Don't forget that you need to buy Apple Mac OS X Lion from the App Store to legally use it.
OS X Lion is the next major release of OS X, the world’s most advanced desktop operating system. It includes over 250 new features that will transform how you interact with your Mac. Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac. And to deliver the most intuitive and integrated computer experience. Brought to us by HOTiSO group. Mac OS X 10.7 was first shown to the public in October 2010. The presentation was understated, especially compared to the bold rhetoric that accompanied the launches of the iPhone (”Apple reinvents the phone”) and the iPad (”a magical and revolutionary device at an unbelievable price”). Instead, Steve Jobs simply called the new operating system “a sneak peek at where we’re going with Mac OS X.”
via gizmodo: a new trojan that addresses Apple's OSX operating system disables your auto-update. Is there a new generation of Apple malware coming?
"The original iteration of the Flashback Trojan was a nasty little bugger, quietly shipping your Mac's details off to a remote server. This newly discovered variant is even worse.
The new version, dubbed Flashback.C, also disables the your Apple's security definition update service by wiping files necessary to run future updates. Both Snow Leopard and Lion are vulnerable, though the Trojan seems to delete itself on any system running Little Snitch. The Trojan itself comes disguised as a Flash package installer."
Intel will bring Thunderbolt to the PC, which means you can use your devices such as the Promise Pegasus Thunderbolt RAID or the Lacie Little Big Disk, but also products such as the black magic intensity extreme Thunderbolt video capture cards on your Windows PCs - and on your hackintosh machines as well.
During Intel’s Developer Forum, the chip maker showed off some Ultrabook prototypes running on its Haswell-based processor and sporting the high-speed Thunderbolt port. The technology was developed in collaboration with Apple and has so far remained exclusive to Macs. That may change soon as Intel teases that Thunderbolt will be heading to Windows PCs as well.
hunderbolt was originally code-named Light Peak and was installed on the update to the Mac Book Pro earlier this year. Rights to the Thunderbolt technology were originally registered under Apple, but were transferred over to Intel which is why you'll see it's name popping up a bit more. We already know Acer and Asus are planning Thunderbolt integration, but we're unsure how the port will look. Currently, the Thunderbolt port on Apple products is identical to the mini-display port, but PC users would rather it be more like USB for increased compatibility. Not to many people are aware of this, but Sony released their VAIO Z with a hybrid USB 3.0/Light Peak port, so it's kind of up in the air as to how things will shape-up.
Expected timeframe: anywhere in 2012.
Its now possible to Install Mac OS X 10.7 Lion on your PC with the standard Hackintosh techniques. That means, everything stays the same to get your hackintosh up and running, no worries. More information on the geeknizer blog entry or alternatively, watch the video below:
Steps to install OSX Lion:
1. Get the "GM" (Golden Master) of Lion via torrent
2. Get an EFI Boot Loader
3. Get a decent 8GB USB thumb drive and install the Golden Master on there.
4. Install using iBoot.

The Apple Macintosh (MAC OSX) Platform is catching up with Windows regarding gaming - while this for sure is attributable to the Steam platform by Valve (which are responsible for great Games such as Portal 2), the latest (and cheapest) way to play quality games on Macintosh are to make use of the "free to play" feature of Steam:
Those games are free to download and free to play. Valve makes money if you are ordering additional items such as weapons, mods and so on. On the example of Team Fortress 2: if you ever spent a dime on the game (or would buy it now) you would get premium features: more Items, full "trading" (sell and exchange virtual goods), gifting, etc.
While this is a new approach to capitalizing games, this can be seen as a positive path, the gaming industry is taking. Why? Because the games have to be maintained longer and the communities around the games can emerge. This means: addons, mods, hacks and whatnot, resulting in "ludic artefacts" (as outlined in the german book "Gaming 2.0"). Also, the ludic artefacts of Team Fortress 2 on eBay are increasing daily.
Currently, the only two Mac compatible games are Team Fortress 2 and Spiral Knights. On Windows, there are much more titles available: Global Agenda, Spiral Knights, Alliance of Valiant Arms, Champions Online, Forsaken World, Team Fortress 2.
To play those Windows-only games on your Macintosh, you currently have two choices: either use Apple Bootcamp or use Parallels Desktop 6 for Mac. I can totally recomment Parallels Desktop, since the Version 6 has a very fast GPU and game performace (cf. Arstechnica about Parallels Desktop 6 Gaming Performance).
As we already blogged some time ago, we had severe overheating issues and frequent kernel panics with our early 2011 models of the MacBook Pro Core-i7 quad. Still, after the updates there are crashes from time to time - the early 2011 models are far away from being stable machines to use for serious work.
After days of trying to figure out what is really the issue, we found that most of the times device drivers or other third party apps are mostly causing the crashes - but also CPU-intensive apps such as games sometimes bring the system down. Solution? Yes, there is one: change your system to a 32bit Kernel.
1) The bootup way (temporary solution, great for testing)
If you just want to test if changing to 32bit changes anything, you can reboot your mac and hold down the "3" and "2" keys as soon as you hit the power button. This boots up your Apple in 32bit mode temporarily. If the system
2) The Terminal Way (see the Apple Support Document for more information)
sudo systemsetup -setkernelbootarchitecture i386
if you need to change your system back to normal for any case, you can enter the following command into Terminal.app:
sudo systemsetup -setkernelbootarchitecture x86_64
Just to make it clear: your applications will still run in 64bit mode, you can make sure this is the case by hitting cmd+i on the application icon and see if "Open in 32-bit mode" is checked. See this article from simplehelp with details and images on 32-bit mode. So why should I care then, you might ask: since drivers and 3rd party apps and extensions that are loaded on startup are most of the time the issue with system freezes and hangs, changing to a 32bit kernel did the trick for us and now we have a stable 2011 MBP quad-core system.
[UPDATE] 10.6.8 seems to work with 64bit kernel much more stable than 10.6.7. Still, to be on the safe side we are using the 32bit kernel and had no freezes yet.
Since we recently purchased two 2011 MacBook Pros (with lots of issues, as previously reported) we were wondering if SATA III 6Gbps drives would be supported. The short answer is YES, the longer answer is: only on the original Hard Drive port. Here are recommendations on which drive setup is best suited for getting the maximum out of the 2011 Apple machines.
Which type are you?
- the collector: two 750GB SATAII Drives
- fast, but not furious: 256GB SSD SATAIII drive + 750GB HDD in the optical drive slot
- the caretaker: 256GB SSD SATAIII drive + 500GB SATAII hybrid drive in the optical drive slot
- speed enthusiast: 256GB SSD SATAIII drive + 256GB SSD SATAII drive in the optical drive slot
- humongous and rich: 512GB SSD SATAIII drive + 512GB SSD SATAII drive in the optical drive slot
The new MCE OptiBay was created for users who want as much hard drive capacity as possible inside their MacBook Pro, MacBook, PowerBook G4, iMac, or Mac mini. Period
Apple original Hardware is very pricy. There are some items which can be bought as replica and are (almost) the same as their original counterparts. But which items should be bought as rebuilt?Good idea: Replica Apple Power Adapters (for MacBook, MacBook Pro, iPhone, iPad). Bad idea: Lithium-ion polymer battery packs.
We recently had bad experiences with non-Apple battery packs, so we can definitely not recommend getting them from another vendor. Good news: if your Battery is less than 300 cycles and lower than 80% of the battery health, they will replace it for you (if you have Apple Care or are within your 1 Year warranty). If not, stay tuned, we will post a guide on this very soon.
Apple replica/ rebuilt Hardware that actually makes sense to buy
1. Apple Magsafe Power Adapters (and G4/G3 Adapters as well)
The cheapest versions are EUR 27,98 for a AC Power Adapter für Apple MacBook Pro MagSafe 85W( even cheaper in the USA: $25.56!) and EUR 21,99 for a 60W Power adapter for Apple MacBook ( only $19.27 in the US!)
2. Apple USB Power Adapters for iPhone and iPod
The Apple original USB Adapter sells for $29 on the Apple Store, while a Multicharger Set (Car, Wall and USB) sells for €4.50 in Europe and $5.47 in the USA. Be careful! I selected items that we already ordered and tested before, there are "bad" replicas as well out there (see this example and read the comments on Amazon).
I will post my experiences with Apple replicas here if I have any news. Currenty, we can NOT recommend the following list of items as replicas:
- Apple Replica Batteries. They mostly died on us too fast. (we will post a specific Apple Batteries Guide in some days)
- Apple Replica Keyboard (not tested) - is this really available somewhere? WTF is this windows key? Although the Macally USB Slim Keyboard - ICEKEY has some good reviews, i like my keyboard to be an original. [UPDATE] the Macally Keyboard has severe driver issues. Not Recommended!
- Apple Mouse Replicas: we ended up going hi-tech with the Apple Magic Mouse which is $67.99 - or just using the Logitech Value Optical Mouse which is $4.99, but can not be really considered a "replica", since the Apple Magic Mouse has soo much more features (wireless, swipe, better optical resolution).
Having a hackintosh can be a good experience, once you get it up and running. According to the geekbench result browser, there are some fast ass-kicking machines out there. Unfortunately, one thing not benchmarked by geekbench still sucks big time: the case. How to find the perfect case for hackintosh computers?
1. Get an original Apple Mac Pro Case (Enclosure/ Chassis) or alternatively: an Apple Power Mac G5 Case to tinker with
You can find Apple Mac Pro Cases (case only) via ebay, although they might be quite pricy. Another option is to search for Apple Power Mac G5 Cases instead, which are sometimes selling for a few bucks (most of the people interested are searching for "Mac Pro" and not for "Power Macintosh"). So while there might be some tinkering required, still the Apple Power Macintosh G5 Case is a very fine piece of casing. (see a howto for G5 Casemodding on Youtube)
2. Almost as good as the "original": Lian Li PC-V1000 computer case
You might get lucky and find the Lian Li PC-V1000 computer case on ebay - unfortunately I did not find any other ways of ordering this awesome case somewhere else.
3. DIY your own.
There are some impressive CaseMods out in the wild (e.g. the Hackintosh Jr. Case Mod). While this might be a lot of work, you will earn lots of (digital) street creds for your "almost impossible mod". Enter hardforum.com if you are brave.
While the new Apple MacBook Pro Machines are really fast desktop-like speed packed monsters, it seems like they also have severe hardware design faults as outlined by zdnet and ifixit. With a geekbench score over 10.000 the new MacBook Pro (early 2011) beats the Mac Pro (Early 2009) Intel Xeon W5590 3.33 GHz (4 cores). All the good talk and benchmarks cannot make up for the current problems Apple users are facing with their brand new machines:
- too much thermal paste seems to raise the CPU temperature
- fans running at 6000rpm+ constantly
- frequent kernel panics or freezes that are maybe related to the new GPU
- heating issues with the whole MBP early 2011 series
Come on Apple, wake up and fix those machine fast, as lots of us could benefit from a stable quad-core laptop solution (talking audio plugs and realtime audio performance).
We can recommend to tell apple to send the replacements before they pick up the faulty machines, so it is easier to transfer the data already on it. (apple care even suggested it this way)
[UPDATE] Gregg Keizer from Computerworld also writes about quality concerns regarding the new Apple Notebooks and there is also a discussion about actual "Overheating" going on in the Apple Forums. Well, I can confirm the issue exists and the current MacBook Pro Models freeze a lot. If it is a hardware, software or firmware issue remains unclear.
[UPDATE] There is a macrumors forum thread discussing that there were issues with the 2010 MBPs as well when they came out. Another thread at macrumors forum tries to sort out if it is a hardware or software issue.
Some people suspect it is related to internal graphics switching, but there really seems to be something going on since also reports on the apple discussion forums are increasing.
[UPDATE] as of 2011/03/14 macrumors suggest in their forum to "go 2010 or wait for ivy bridge". The early 2011 version of the MacBook Pro das 45W TDP vs. last generation's 35w. That's a big increase which automatically makes the whole series go louder and more hot than the 2010 model.
[UPDATE] 2011/03/21: Macrumors posted a story: "2011 MacBook Pros Crashing Under Load?"
[UPDATE] 2011/03/21: Mac OSX 10.6.7 Update was just announced by Apple. Unfortunately, on the two machines we have here, the update does not fix anything related to CPU temperature. Still there are frequent freezes as well.
[UPDATE] 2011/03/22: dailytech confirms that New MacBook Pros Freezing When Stressed, Update Adds More Problems
[UPDATE] 2011/03/28: we received our two replacement MacBook Pros. They don't seem to have any issues and also still did not freeze on us! Also the fans are not spinning like crazy anymore! For all people affected by any of the issues reported above: get your Notebooks replaced! Apple is aware of the issues and replaces faulty hardware (we had to wait for two weeks though).
[UPDATE] 2011/04/23: the current Systems freeze 2-3 times a day. Not all the issues seem to be solved! You should definitely get a late 2010 model, if you need a highly stable system!
[UPDATE] 2011/11/01: Apple replaced one of our 15-inch MBP MC721LL/A machine and the freezes are not appearing anymore. Reports from other users that bought an early 2011 model are positive, so currently the advice would be to get a refurbished Apple MacBook Pro MC721LL/A 15.4-Inch Laptop even before getting a MD318LL/A 15.4-Inch (late 2011) version, not only because of saving some bucks, but also since the Apple MacBook Pro early 2011 performs better in most of the situations compared to the late 2011 version.
Besides the heating issues, there are also reported "intermittent flickering, brief blackouts and other periodic but noticeable flaws" reported in the Apple Discussion Forums. We are getting replacement Machines - let's see if there is any improvement after the first round of shipping!
[Update 2012]: using Multibeast is the preferred way to install 10.7 Lion or 10.8 Mountain Lion
see the Nanofunk Post: Booting and Installing Mac OSX 10.7 and 10.8 Mountain Lion on Hackintosh
"lion is booting with some old xpc version" ~ Netkas
Some people are claiming to boot the recent Mac OSX 10.7 Lion with the XPC Bootloader project. More and more voices are popping up, so I am just pointing in the right direction, since "Any and all information about downloading and installing Lion, as well as any details are under Non-Disclosure Agreement from Apple.". You probably find updates on Netkas' Blog as well.
UPDATE: see a posting/ short guide on a popular board as well: Mac OS X 10.7 Lion [Beta/HowTo]
