Thread: The Guide for Installing “OS X Mountain Lion 10.8” on LenovoG570

The Guide for Installing “OS X Mountain Lion 10.8”
Requirements:1
⇒ Mountain Lion app from Apple Store or downloaded from Torrent. Here is the link…
⇒ 8gb or more flash drive for making installation usb.
⇒ Already working Snow Leopard or Lion for making bootable usb flash drive.
⇒ myHack, can be downloaded from the link here…
⇒ The kexts for your Lenovo G570 can be downloaded here.
⇒ Chameleon Wizard is here.
⇒ Chameleon Bootloader is here (in case myHack’s bootloader doesn’t work)
⇒ Kext Beast from Tonymacx86.com.
Preparation:
⇒ Plug in your flash drive and head over to Disk Utilities and click on the flash drive.

⇒ Click on the Partition tab and then select Partition Layout 1 Partition.

⇒ Now click on Options and select Master Boot Record and click Ok.

⇒ Click Apply and select Partition to make the partition.

Here we have done with it now close the Disk Utility and install myHack, which can be downloaded from the link above in the Requirements section.


Run myHack and enter your admin password to proceed.

Now select the option from drop down menu “Create OS X Installer” click Ok.

Choose install type “Create OS X 10.8 Install Disk” and click Ok.


Now select your flash drive.

The dialogue will appear to find the installation source, I suggest you to click on the “Browse Manually” because it’ll take less time.

myHack will mount the InstallESD and ask it’s ready to copy the files in the flash drive.

Click Ok to continue and be patient it’ll take 10-15 min or depending on the speed of your flash drive.
After you’re done with myHack, one thing more you’ve to do is to place the “smbios.plist” (provided in the requirements section) to boot from installer usb.
Note: In my case the bootloader installed by myHack did’nt work so I used Chameleon bootloader (also in requirements section).
Now restart your computer and bootfrom usb if your bootloader doesn’t get you on the installer screen then you’ve to install the bootloader mentioned above in a separate flash drive.
After successfully getting the installer screen, install the Mountain Lion in the disk you’ve chosen for OS X. Don’t worry about MBR (Master Boot Record) hard drives it install on MBR and GUID as well. myHack done this trick.
Once you’ve installed now need to remove the graphics kexts by entering in the single user mood to get the shell access.

Here are the commands used for removing the graphics kexts.(assuming the OS X installed disk name is Macintish HD)

You’ve another option if you’ve Windows installed on the other partition you can install MacDrive to access the OS X disk and move into the /System/Library/Extensions and cut the graphics kexts and reboot the computer to boot into the OS X boot it with –f bootflag. Hope you’ll get the desktop.
Before installing the kexts you’ve to install smbios file with Chameleon Wizrd (available in the requirements section).
Now you’re to install the kexts using KextBeast available on Tonymacx86.com (you need to register to download). All the kexts are available for download the in the requirements section.
The working hardware:
Wifi (with IO80211Family.kext)
Ethernet
Sound (with VoodooHDA.kext and AppleHDA.kext)
Display (with kexts, QE/CI working)
Bluetooth (OOB)
The not working hardware is: Card Reader
The problem is CMOS reset; I tried patches but didn’t work. Still searching.

I have a G570, with a Pentium Dual core, HD 3000,4gb ram, and 500 gb hdd, 15.6 LCD and wifi atheros 9285. The problem is when i try to install OSX to it , it loads the apple screen, then after a bit freezes, although the kb still functions, but all i see is the apple screen. i tried your directions, but i have a question, where do i get the smbios plist? your directions about where to get it are vague. Also is the pentium dual core (its a sandy bridge variant) compatible with OSX?, oh and its 64 bit as well..

Yes it supports, you can get the Smbios.plist from the previous Lion installation or download from here...SMBios.plist
