Go to your BIOS settings and change IDE to AHCI

 

Mac OS X can't see IDE.

 

I think this should solve your problem

 

my BIOS has no such setting :( any ideas?

Please post photos of your bios settings, every screen

 

Sony have completely dumbed down the BIOS, the only real editable option is "Virtualization" which you can turn on and off, apparently you have to hack the BIOS to enable more settings, but I can't find any help on how to do it for my model of Vaio :(

I have a short question to 10.8.1 with no sound on a GA-P35-DS4 with F14 BIOS. I tried to get the sound working but with no success. I made a clean install with a different installation guide and no DSDT. So everything is working but no sound. I'm not used to work with DSDT, that is why I've not tried to fix it with editing a DSDT.

 

Is there a simple way to exchange the native appleHDA.kext with a fixed one, or do i mix up everything here? Sorry for being a noob on that...

 

What can I do to get sound working easily?

 

Any ideas?

Yes. Use this installation guide. :)

 

If you don't want to start from scratch you can try making the USB and running finalize on your current installation. That may or may not work.

Hi,

I have purchased and downloaded ML from App Store but is now updated to 10.8.1, i then followed the guide.

 

The mkboot results in Checksum fail. - I am using 2009 MacbookPro 15 OSX 10.8.1 to mkboot

I can't download Install.zip because the website is seemingly blocked in Saudi Arabia. -_-

Most likely a bad image. Redownload from app store.

I followed the guide, the mkboot procedure works fine, but I can't get the usb drive to boot. I have GA-P35-DS4 v 2.0 (F14 BIOS).

I'm using a OS X 10.5.8 hackintosh to create the usb Mac OSX Base System ('boot') install drive.

 

-I've tried using a 16gb SD card (in a USB card-reader), an external USB HDD (formatted with a GPT table in Parted Magic, and with a 20gb HFS+ Volume created in Disk Utility), and a SATA connected HDD.

-I disconnected all the other drives other than the target (the drive I want to install ML on) and the install drive.

-I set the BIOS boot order for the correct drive (after enabling 'Legacy USB support' in the BIOS settings) but after POST there is the usual "Verifying DMI Pool Data.............", then nothing happens.

 

I've tried to boot the drives on two other computers with the same lack of results (the disk are recognized but don't boot).

 

In Tseug's guide for installing Lion, by this same method, there were posts from people who had this same problem; apparently it had something to do with the Chameleon bootloader, and they had success by using a different version or modifying the version included in the Install package.

 

How would I go about replacing the Chameleon version in the Installer package? Or could I just replace it on the Mac OSX Base System ('Boot') drive that I have already made?

Can I just add on a different version of the Chameleon bootloader instead of Enoch-rev.2009 and then edit the bash scripts to point to the new version instead of Enoch-rev.2009?

Or, is it the fact that I'm using OS X 10.5.8, do I need Snow-Leopard, or later, to create the USB install drive?

 

Please help, thanks.

did you get the combo update or just ran the app store installer? Also did you have to rerun the finalize script or adjust any kext to get sleep back?

 

I just ran the App store installer. I didn't need to do anything else.

OK, could somebody nice just answer a simple question for me?:

 

Is there supposed to be a chameleon boot file in the root of the Mac OS X Base System drive (the one that has the mkboot install)?

 

No matter what version of Chameleon I install, on any HD partition or USB drive, there is never a boot file in the root of the drive after installing chameleon, and the drives never boot.

 

I have been trying just to get a successful install of ML for the last week, about 7 hours a day; the only way I can even get into the Mac OSX installer is when I install PC-EFI 10.6 with the 10.7 boot file onto a boot drive and then select Mac OS X Base System.

But, of course, you can't get a successful install of ML from a 10.6 bootloader.

 

So is there something wrong with the way I'm installing Chameleon? Is there supposed to be a boot file in the root of the drive after installing it?

 

Thanks.

I have the 9800 (512mb) and the GA-EP45T-DS3R. Getting KP every install attempt.

 

I'm using "-v GraphicsEnabler=yes PciRoot=1" - this gets me past black screen.

 

Anyone have any thoughts. Thanks.

Hi,

I'm trying install 10.8 on my P35-DS4, Q6600@3,15, 8G RAM, Nv8400GS 512M

Using exactly guide from this thread I was able install 10.8.

With -v kernel boots till assertion in AppleHDA and then hangs (see attached pic)

Maybe issue is related to my gfx (8400GS 512M) ?

I was trying add gfx properties into /Extra/com.Apple.boot.plist extracting them from my working 10.7.5 install (see attached).

No any change.

 

I can boot system into gfx mode with vai safe mode (-x) but it has only 1280x1024 and no any gfx hw accell.

 

Have anybody idea how to enable full gfx support ?

 

Thx in advance

com.apple.Boot.plist.zip
