This guide is already outdated, you must read to know what you are doing, but, to

properly set your SMBios options, use Chameleon Wizard instead of Lizard > http://www.osx86.net/downloads.php?do=file&id=2440

Hy People!

As time goes by, the developers of the world are implementing Hackintosh

improvements that we can add to the bootloader to increase performance

of our machine.

But if our settings are not correct, we can not enjoy this improvement.

One of those responsible for increasing the performance of the machine is the file "smbios.plist", that when

used with the bootloader and a DSDT file with all the patches needed to

your "Motherboard", can offer a machine very close and sometimes even better than one

Real Mac (in comparing the performance of the OS and not the hardware itself and Design) and provide

better power management.

In order to let our machines better and better, I'm creating this topic to

learn how create the file "smbios.plist" and let our Hack the closest our settings

allow it to resemble an original Mac.

To begin, we will need a free app called Mactracker you can download from the link below ...

Mactracker - Get Info on any Mac


As you can see, it has a comprehensive database of all Mac models released to

the atual date ...

The first thing we need to do is find a model that comes closest to our

configurations, that are, Processor Type, Processor Speed ??and FSB processor.

In my case, I use the specifications for a MacPro3,1 Early 2008.

For machines with Core i3, 5 or 7 the models that should be used are MacBookPro 15" Mid 2010,

iMac 27" Late 2009, MacPro Mid 2010 or later models.


After finding the closest model to yours, you will need Lizard by sonotone to create your file


Lizard (unofficial) - Downloads - Kexts.com

Once you download, run the app and go to tab "SMBIOS Options" and fill in the information

according to that obtained from Mactracker.


In "Boot ROM Version", if it does not automatically generate a number, use a similar setup and then just

change the opening sequence in the file as in the examples below ...

MacMini 2,1= MM21...

MacBook 5,1= MB51?

MacBook Air 2,1= MBA21?

MacBook Pro 5,1= MBP51?

MacPro 3,1= MP31...


The "SMBIOS Version" don`t need to be changed.

In the "Serial Number", click the "Build It" button and will appear a window like the example below ...


Complete the required fields and only in the "Year", set one year from the date of

manufacturing and introduction of your model ...

In the "Bios Date", use the same concept as stated above for the "Year".

The last step is the memory settings ...


Fill out the fields according to your memory settings ...

Finally, click "Save" ...

If you don`t have, create this key in your com.apple or org.chameleon.Boot.plist on /Extra folder...

If you have doubts on modifying the file > http://www.kexts.com/guides-tutorials/10747-guide-chameleon-bootloader-basics.html


Or if you prefer, still in Lizard, go to "Boot Options / Custom Paths / smbios.plist / Select" and navigate to the file

"smbios.plist" that you just created ...

Okay, now is just restart the machine and see if the information was read correctly, for that, go to

"Apple Logo / About This Mac / More Info / Hardware"

As I said , this is not the only thing that will increase the performance of your machine, however,

it`s a good start ...

I need a MacBook Pro 8,1 smbios. I've managed to use ModCD to boot a vanilla retail disk, and install Snow Leopard 10.6.3 on my Lenovo B570, thanks to some stuff on the InsanelyMac forums. However, the interwebz are veeeeeery vague as to where to find a good smbios.plist without having a Mac already on hand, and I've been told that without that file, I won't be able to boot the install I've been trying to get working for over a week. :mad: It is what it is, but thank you very much,ahead of time. You are the ONLY person willing to help.

Lizard doesn't have a MacBook Pro 8.1 option, but there are more ways to make one :)

MacBook Pro 8.1 is for Sandy Bridge Mobile.

Intel Core i3 2310M = Sandy Bridge.

If you want changes just ask.

Here you can find more Extra folders with SMBios

You have to register for free to get the downloads.

By the way, Sandy Bridge needs 10.6.8 at least.

Would it be easy to make a SMBIOS for my build:

16GB Gskill Ripjaw DDR3 1600 memory


GIGABYTE Ultra Durable VGA Series GV-R685OC-1GD Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 videocard

Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000

GIGABYTE GA-Z68A-D3H-B3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
