Snow Leopard 10.6.8 On Lenovo G770 i5 Sandy Bridge Laptop

2012-08-16 Prepare and fix dual boot for lenovo.

And always use portable drive to install before internal hard drive. For Realtek id 0139 card reader isn’t supported, a USB SD card reader is handy.

May 17, 2012 If you’re not familiar with chameleon, there’s a way to dual boot using windows 7 and EasyBCD on 750GB hard drive here.

2011-12-26 For those who want to boot from WDC 750 GB, I use the original MBR formatting on the hard drive, use Windows 7 to shrink a partition for Snow Leopard 10.6.8. Use an external USB hard drive to load Snow Leopard 10.6.8 or LION first, then restore the partition to the internal hard drive partition. When done, remove the hard drive, connect this hard drive to an external USB, install Chameleon on the 100MB MBR partition, copy the Extra folder to this MBR partition (after Chameleon installation). Make sure we can still boot the drive (in USB connection), then put it back to the LAPTOP, it will boot using Chameleon boot loader.

I’m writing up a tutorial on how I intalled Snow Leopard 10.6.8 with full QE/CI/CL & resolution 1600×900 & Atheros Ethernet/Wifi & sleep working on my Lenovo G770 10372LU laptop model. I need these software to make it work. I think this laptop is the best for Snow Leopard 10.6.8 and Lion at the moment. This Lenovo has the important devices that work/not work with Mac OS X at the moment, please identify your hardware because G770s do come with different devices. Check for Graphicsid, Wifiid, Ethernetid, SDcard readerid. My SDcard id is not supported at the moment. Thanks to many techs savvy on the net like Maldon, Bcc9, I could get these going so well. MAKE SURE TO BACK UP THE IMAGE OF THE HARD DRIVE BEFORE DOING ANYTHING TO THE LAPTOP.

Software and hardware needed.

* iboot-legacy, multibeast, updatehelper

* An external USB hard drive: we will need this one over and over for installation, experimenting snow leopard 10.6.8 and lion then restore it to the internal hard drive after we’re happy with our MAC OS X. DON’T install on the hard drive without knowing if it’s going to work.

* Patched kexts for Ethernet & Wifi & trackpad
