Hi Guys,

I need your help in instaliing OS X ML on my dell xps 14 ultrabook.
The system config is as follows :
Intel Core i7 3517U @ 1.9GHz
8GB RAM and a sata HDD - 500GB

I have tried various methods and have never succeeded to get to the installer in the first place.

After lot of research and reading I have patched my DSDT, removed unnecessary kexts, booted using various flags but to no avail.

The various methods I have tried but not limited to are ###### from tonymac's , myhack 3.1 and various distros like iAtkos, etc. I have also tried the generic way through chameleon bootloader 2.1 and patched my DSDT.

I got stuck in the boot process itself and the most common error I received was "Still waiting for root device"

I have tried various boot flags like USBBusFix=Yes PciRoot=1, etc. to fix that but never succeeded.

Will greatly appreciate any help.

Regards
Shameer

Thanks for the reply mate. Yes, I am already using that kext. I'll try deleting the kexts you have suggested.Do you want me to try installing through some distro and remove the kexts from that distro or should I do the changes to the original appstore ML? Which one would be a better choice?

Thanks

Ok. Will give this a try. But are you sure the ML installer will work fine with GraphicsEnabler=No cuz I have heard that ML needs the GraphicEnabler to be ON. Btw I have the intel HD 4000 in my laptop and also the nvidia GT630m on optimus..

Will give this a try and post the results. Thanks again

Hi artur-pt,

I have done removing all the kexts that were unnecessary. Now, when I am booting in verbose mode it restarts automatically as soon the DSDT and SSDT are identified. Looks like I have a problem with some part of my DSDT. I have extracted it in Ubuntu and also in Windows using aida64. I have patched the DSDT with snippets from this guide below :

http://www.insanelym...-and-xps-m1730/

Now the only real problem left is the DSDT and SSDTs. Can you please help me in this regard? [I have tried various codes to prevent the BIOS from restarting but could not succeed.]

Thanks

Hi artur

I have tried many different combinations of kexts and boot flags but seem to get stuck at every point of time. Here are some basic doubts I have about the installation:

1)Should Intel Speedstep be enabled? I have tried both ways though

2)I am using the following boot.plist. Can you please confirm whether this is right?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com...yList-1.0.dtd">
<plist version="1.0">
<dict>
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>GUI</key>
<string>No</string>
<key>GraphicsEnabler</key>
<string>No</string>

<key>Kernel Flags</key>
<string>npci=0x2000 root-dmg=file:///BaseSystem.dmg DarkWake=0</string>
<key>Rescan</key>
<string>Yes</string>
<key>Timeout</key>
<string>5</string>
<key>USBBusFix</key>
<string>Yes</string>
<key>UseKernelCache</key>
<string>No</string>
</dict>
</plist>


3)I am using the following smbios.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com...yList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>SMbiosversion</key>
    <string>MBP81.88Z.00A5.Bnn.yy11031449</string>
    <key>SMboardproduct</key>
    <string>Mac-94245A3940C91C80</string>
    <key>SMfamily</key>
    <string>MacBook Pro</string>
    <key>SMproductname</key>
    <string>MacBookPro8,3</string>
    <key>SMserial</key>
    <string>C02XXXXXXDF8V</string>
</dict>
</plist>

Is everything right or should I make any changes?

Thanks & Regards

[artur-pt]

http://www.olarila.c....php?f=17&t=134

Is this the 14z you're referring to? Or if there's a difference between the 14 and the 14z, what is it?

What's the furthest you've come to the installer (in GUI, not verbose)?

Hi Zack,

Yes, the 14z is different for XPS 14. Basically 14z is inspiron and the other one is XPS 14 ultrabook.

Here are the links -

Inspiron 14z Ultrabook - http://www.dell.com/...d?~ck=mn&~ck=mn

XPS 14 Ultrabook - http://www.dell.com/...en&s=dhs&~ck=mn

Mine is the XPS 14. In the GUI mode the farthest I can get is - the apple logo keeps spinning and after some time a stop symbol appears in the middle of the screen, i.e., some error.

In the verbose mode I always fail at some point which include failing to load some kexts. Tried deleting them but no success. It always stops at "still waiting for root device".
Tried many boot flags and the smbios and boot.plist as mentioned above.

Any ideas?

Thanks & Regards

[ZackehSoul]

No I mean there's an XPS 14z too, not the Inspiron. Do you know the difference between these?

Depending on the difference, I can probably get it working but the system is difficult to configure properly once it's installed.

As far as I can find, I do not see a XPS 14z in either dell USA or dell India. But here's my config :

Intel Centrino Advanced-N 6235 and Bluetooth 4.0
3rd generation Intel® Core™ i7-3517U processor (4M cache, up to 3.0 GHz , TPM)
Backlit English Keyboard
14.0" HD+ (1600x900p) True Life Infinity Display with Skype-Certified Hi-Def Webcam
8GB DDR3 1600MHz (8GBx1)
128GB mSATA
500GB 5400RPM Hard Drive
Intel HD 4000
NVIDIA® GeForce® GT 630M with 1GB GDDR5 VRAM (Optimus)
69 WHr 8-Cell Battery

Please help me out with this. Thanks in advance buddy.

Regards

Alright, think that's the same pretty much as what I'm talking about. Maybe the 14z was just the UK model of the XPS 14 Either way I'll outline what I found on the 14z during the couple of days I had it and you might as well try it anyway.

So, create an installer just by restoring the BaseSystem to a USB and then copying Packages over the symlink which will exist. Then install Chimera bootloader to it (since it uses graphics that Chameleon doesn't support). You'll have to erase the graphics kernel extensions, so run the following via Terminal, you might need to run them as sudo.

rm <pathtoyourinstaller>/System/Library/Extensions/AppleIntelGMA*
rm <pathtoyourinstaller>/System/Library/Extensions/AppleIntelHD*
rm <pathtoyourinstaller>/System/Library/Extensions/AppleIntelSNB*
rm <pathtoyourinstaller>/System/Library/Extensions/ATI*
rm <pathtoyourinstaller>/System/Library/Extensions/NVD*

After that you should be in the installer with no issues I think. Don't use any specific boot flags etc.

Hi Zack,

Thanks a lot buddy. Will try it. But can you please tell me what are packages over symlink? And after this should I not install fakesmc or will chimera do it?

Thanks again

[ZackehSoul]

Oh, restore the BaseSystem.dmg from your Mac image to your USB then go to /System/Installation on the installer and delete the Packages file, then copy the Packages folder from your Mac image to the place the file was. And no, FakeSMC isn't needed

Hi guys,

Like shameersyd, I also have the same ultrabook and trying to install 10.8 on it. So far I was able to install it using UBeast method (no DSDT) and as of now I am stuck finding the correct audio kext to get the audio working. Supposedly its ALC3620. I'm not sure if it's supported in OS X. Any ideas will be greatly appreciated.

Best regards,
Djuby

[justlearning]

can we please keep this thread going??  I still have this lovely lappy from years ago that i got SL working on like a champ.  We have some Mountain Lion success here?

Can people try and make a habit of posting DSDT and plist files?  I think it would really help out progress.
