We just finished our latest Hackintosh 8-Core build that we wanted to share with the community. Here are the specs:
Motherboard: Gigabyte GA-X79-UD5, X79 (quad PC3-10667U DDR3)
CPU: Intel Xeon E5-2690, 8x 2.90GHz, Sockel-2011, boxed
RAM: Kingston HyperX Beast DIMM XMP Kit 64GB PC3-17066U CL11-12-11 (DDR3-2133)
GPU: EVGA GeForce GTX 680 Classified, 4GB GDDR5, 2x DVI, HDMI, DP (1111MHz)
CASE: Fractal Design Define R4 Titanium Grey Computer Case
We bought original Apple peripherals, such as the Magic Mouse and an Apple Keyboard. If you care about Apple Replica Items you might want to read our previous article: Save Money with replica Apple Hardware: the good and the bad.
The system has a Geekbench score of approx. 30.000, so it is perfect for doing media and encoding work (Adobe Premiere, Pro Tools, Final Cut Pro, etc.).
The early 2011 MacBook Pro is Apple's masterpiece, no doubt: besides the overheating problems that many of us reported (but which seem to be solved as of now). Core i7 MPBs are super-fast with a Geekbench score of over 10.000 points for the i7 quad-core version - this was and still is an awesome performance for a notebook.
If you are planning on buying a new MacBook Pro 15", keep in mind that newer does not necessarily mean better: the early 2011 MacBook Pro is currently the best deal you can get ($1,549.99 for a new, $1,499.99 for refurbished MC721LL/A 15.4-Inch quad Core on Amazon) especially since they fixed all the flaws people reported about. I was complaining about issues a lot, but after Apple replaced the two notebooks we had, the run smootly ever since.
So a clear winner for buying a new MacBook Pro in 2011/2012 is the Apple MacBook Pro MC721LL/A 15.4-Inch early 2011 model that performs better in most of the situations compared to the late 2011 version (review and benchmarks by anandtech).
Install OS X 10.7 Lion on any Supported Intel Core 2 or Core i based PC & Make an OSX Lion Boot Disc
TonyMac recently described how to install Apple OS X 10.7 Lion on any Supported Intel Core 2 or Core i based PC. Here is the short version:
1. Get Mac OSX 10.7 Lion
A Retail Version has already been spotted in the german amazon store but it seems the product has already been removed from amazon. Other ways to create a bootable Lion DVD are outlined here:
2. Get a Cheap USB Stick that works with OSX
Of course, you can also try the method outlined by tonymac: Installation of 10.7 Lion with Snow Leopard and Boot Partition. Please post any success or fail information in the comments section.
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.
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!
