Snow Leopard 10.6.8 On Lenovo G770 i5 Sandy Bridge Laptop

05/29/2018 These methods are no longer supported and working…

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.

  1. Hi,

    I have used this process, your process and it works great. There is one thing I noticed. Random crashes. Where I will just have to reboot. Strangely enough, i found these only happen when i use the Ethernet port. With wireless, it is rock solid. Is it possible i need a kext other than what you have here?

    Thanks a lot.

    1. Hello,
      I haven’t used ethernet much to connect to the internet so I don’t notice the crashes. If the ethernet works, the kext you’re using is correct, when it crashes, it’s the software you’re running. Why not Lion?
      Cheers,

      1. Hi,

        I am looking at your lion install and have created the bootable usb. Using LION 10.7.2 and MY Hack. But some of the instructions on what to do with the extra folder is confusing.

        Also, I understand what you are saying about the kext. But I have been doing heavy multitasking and copying large files to and fro across the lan using wireless with 0 crashes. If I connect via Ethernet, then start a transfer across the LAN and say, browse the web. It will crash. I didn’t believe the results either.

      2. Ooops BTW thanks for your timely response. And this site is great.

  2. Dog, great tutorial and videos. Before I give this a shot, I wanted to ask a few questions to make sure that this will work well for me:

    1) Will this setup (once completed via dual boot option #2) be capable of using MacOSX’s Software Update utility to install future Snow leopard OSX updates, or will I have to stay at 10.6.8? (It’s no big deal, just curious if future updates for either Snow Leopard and/or Lion will require additional work to install on the laptop).

    2) Is there any special tricks to backing up the dual boot system so that I can easily restore the entire setup without repeating all the steps again? In addition, would a single boot (MacOSX only) simplify the backup/restore significantly?
    FWIW, I would like to use continue to use SuperDuper for my full backup/restores, and TimeMachine for my incremental ones… I am not opposed to using other software if necessary, mainly curious if superDuper would/should work for full backups/restores.
    NOTE: My main concern is to have a simple restore solution in case the hard drive fails, be SUperDuper or some other package you recommend. I figure it’s important to know before starting since HDD manufacturer’s don’t make ’em like they used to 😉

    3) Speaking of HDD failures, is this setup at all tied to the WDD 750GB drive? For example would I be able to upgrade to an SSD or hybrid in the future by doing a simple restore (sort of tied to question 2 in a way).

    Thanks in advance, and again, great job on the tutorial.

    1. 1) Will this setup (once completed via dual boot option #2) be capable of using MacOSX’s Software Update utility to install future Snow leopard OSX updates, or will I have to stay at 10.6.8? (It’s no big deal, just curious if future updates for either Snow Leopard and/or Lion will require additional work to install on the laptop).

      I believe Snow Leopard ends @10.6.8, Lion is the new operating system and it doesn’t upgrade with hackintosh at all because we have to buy the OS @29$ on line.

      2) Is there any special tricks to backing up the dual boot system so that I can easily restore the entire setup without repeating all the steps again? In addition, would a single boot (MacOSX only) simplify the backup/restore significantly?

      Very good question, I haven’t thought of this yet, I backed up the hard drive BEFORE the Mac OS X installation using Windows 7 image back up. It doesn’t work after we installed Chameleon over the MBR. The best is to try Tom’s dual boot with Easybcd (which does keep the windows MBR), back up the windows images only.

      3) Speaking of HDD failures, is this setup at all tied to the WDD 750GB drive? For example would I be able to upgrade to an SSD or hybrid in the future by doing a simple restore (sort of tied to question 2 in a way).

      This set up is for all Hard drives, but WDC750 seems to be the most problem ones. SSD, I have no idea.

      I you install LION, it will upgrades well without doing anything, the only problem you will have is the AppleHDA.kext that needs to be removed before reboot for the VoodooHDA.kext to work.

      It’s good that you do research before messing with the original Hard drive. That’s why I strongly recommend to install Mac OS X onto an EXTERNAL USB HARD DRIVE and back up all original Hard drive images.
