Are you using the aluminum keys macbook pro? I have that same model that I use as a media machine and would love to play with ML on it. I thought Core2Duo machines were not officially supported and couldn't install ML on it.

All unibody Macs are supported that includes iMac from 2008, MacBook Pro from 2008, Mac Mini from 2009 and Mac Pro from 2008. Im using the 13" MacBook Unibody that looks like the current MacBook Pro just without the SD card slot

Heres a pic for reference regard. on the Mac i used.

Now installing ML on a separate partition using the app directly from lion. No DVD or USB required with the image.

Will then try the manual kext move then terminal and see how I go.

Please boot in verbose mode (cmd+V) and post the kernal panic messages thx[COLOR="#808080"

Unfortunately I reinstalled everything and forgot to do that. Have just followed instructions regarding manual installation. No crashes this time but doesn't appear to be loaded. No acceleration so far.

Have you blessed the kext in Single User Mode? Make sure you changed the AppleIntelGMA950.kext to your graphics card kext name.

Followed the three terminal commands 9so not a Terminal user here) hahah - Know how to boot single user but not sure how to bless.

Maybe the x1600 need more than just the kexts you are trying. Have you tried copying all the ATI kexts?

[freedevil]

Do you know what drivers are needed for Imac 6,1 Nvidia Geforce 7300 GT? Thanks.

This was the first thing I tried which resulted in the Startup Kernel Panics. Still trying things and will keep u posted on any developments. Apart from the video it's all working as it should.

[ayilm1]

geforce 7300:
• Relevant geforce kext
• NVDANVHalG7xxx
• NVDAResman
• NVDAResmanG7xxx

ati:
• ATIRadeonXXXXX
• ATIxxxxController
• ATIFB
• Relevant GL/GA/VA bundle

Add your IOPCI String into ./ATIRadeonXXXXX.kext/info.plist

Hi there. I have a late 2007 white macbook, id macbook3,1 with GMA x3100 integrated graphics, and was wondering if anyone has managed to successfully upgrage to ML with GMA x3100, and is it stable. I have the use of a supported mac to give this a shot, but would like to know if it's stable before trying it out.

Thanks

Yes, I have successfully upgraded to ML using this method: http://www.j4mie.co.uk/blog/2012/02/...n-on-macpro11/

The problem is that there isn't a x3100 kext for 10.8 yet so the graphics look a bit weird and the display doesn't turn off in sleep mode. Everything else is stable, though.

Thanks, I'll go ahead with the upgrade to ML, just wanted to make sure it was stable.

Have you seen this guide?

http://www.j4mie.co.uk/blog/2012/02/...n-on-macpro11/

It seems that this guide is also suitable to MacBooks (read comments; there is a user who successfully installed 10.8 on his MB early 2008).

Yep, that's me ;-) It works except for changing the brightness or entering sleep mode. Also, the graphics lag when entering Mission Control or Launchpad.

Sounds like your graphics card is not being loaded and you dont have QE/CI. Your screenshot on your site shows the card only has 8mb memory. Does force loading the Nvidia 7300 kexts from lion work for you? When the graphics are rendered by the software renderer you cant adjust the brightness or sleep.

No, the site isn't mine, just the comment on the site ;-) Seems like my graphics card isn't loaded either, though. I guess that's because of the missing kexts. It doesn't even show the name of the card in system information. It just says "spdisplays_display". Do you know a way to solve this?

I dont have a mac pro so I cant experiment
From looking through this thread youll need kexts similar to these from your "/System/Library/Extensions" folder in Lion.

NVDANVHalG7xxx
NVDAResman
NVDAResmanG7xxx

I think NVDANVHalG7xxx is actually NVDANV40HalG7xxx.kext.

"Kext Helper b7" is a good program to use to install kexts by the way

@MacBooker4,1:

What about these 64-bit kexts? Could they help? I have no clue how to use them, but maybe you know ;-)

Thanks! I had just found the same page when I read your post. They're not perfect (I still can't watch youtube videos) but my graphics card is recognized by the OS now and there are hardly any lags now.

Basically you're in framebuffer mode.. There is a few more kext that you need to install.

for Mac Pro, i highly recommend you to change the graphics card, even if that card works, it wont work well.. Very laggy even on Lion

Sounds like the kexts are not installed, try installing the required kext with KextHelper.

I have the same MacBook 4,1 and installed the x3100 kexts using KextHelper and have the same issues. I installed all five files relating to the x3100 in the /System/Library/Extensions folder from Lion using KextHelper. Are there other files in that directory that need to be loaded for the card to function properly?

[Michelasso]

I installed ML straight into an external USB disc from Lion, building the ML installer as described in this blog:

http://www.j4mie.co.uk/blog/2012/02/...11/#comment-44

It works fine, apart from the lack of graphical HW acceleration (no GMA 950 kext). So I checked the guide here, I'd like some clarifications about this two points:

kextcache -k /Volumes/~MLPartitionName/System/Library/Extensions

I can't find any /System/Library/Extensions.mkext file nor a "-k" (lowercase) option for kextcache. With the GMA 950 kext from 10.7.3 the WindowsServer keeps crashing before to show the login-window. I managed to make the HW acceleration working installing a GMA 950 kext found in an hackintosh site. But that was for versions 10.6.2-10.6.7. Still it works, it does the acceleration, but most videos are blank.

Do I have to get the kext from 10.7.0 as I think I've read in another post? Which kext from which OS X release did you use for the GMA 950? Where can I find them?

I got the 10.7.0 kexts from installing in a VM as all my Macs are at 10.7.3. However, WindowsServer crashes regardless and I can only get the MB to start by removing the kexts.

This is a Macbook 2,1. You can only get the GMA950.kext and the GMA950VADriver.bundle from the 10.7.0 installation media. The final item, the GMA950GLDriver.bundle (typo in the original guide) seems only to be created on actual installation.
