Mountain Lion on newer PC (Intel HD 4600)


10 posts in this topic

Recommended Posts

Hey all, I've got a fairly 'new' PC and I've successfully installed Yosemite so far with no big issue.

However, I need to install Mountain Lion 10.8.5 for certain software compatibility.
I'm currently stuck on the dreaded IO Bluetooth error / Graphics issue which pops up no matter what bootflag I enter (Clover bootloader).

I'd like to clear things up for myself and others trying to install a slightly older version of OSX on a newer machine.
Is there any possibility for a solution or am I just going in circles!?
I have no experience editing DSDT files and I've yet to manually install any graphics kext.
Would love to hear from anyone that has been through a similar experience.

Cheers thanks

Thank you.
Disabled VT-D already.

I've been advised that the Strix 970 GPU is incompatible.

So I'm trying my luck with the 4600 HD

I've tried -v IGPUEnabler=Yes, GraphicsEnabler=No

However I have tried both Intel and Nvidia seperately.

nvda_drv

 

Edit: I've also tried safemode with no success. -f and the following fix to no avail.
Type: mount -uw /
Type: cd /System/Library/Extensions
Type: mkdir intel_back
Type: mv AppleIntelHD* AppleIntelF* intel_back/
Type: touch ../Extensions

 

Disable Vt-d in your BIOS.

 

What boot-args have you using for boot OS X?


EDIT: But, hmm, what Video Graphics you'll use? Intel HD or Asus Strix 970 Gpu:wacko:

Use this boot-args:

-v nv_disable=1 

Open your config.plist, and use this:

Thanks, Im giving it a shot now.

 

Edit:

 

Getting CPU Halts/ Read only errors, not sure exactly the case but I tried moving kexts earlier via Windows.

Currently doing a complete reinstall of Mountain Lion then business as usual.

Will post back asap.

Currently I'm stuck on,
Missing Bluetooth Controller Transport!
Shortly then after:
DRMStatus: iTunes/Apple Store Content Access Problem.
Also I see a Warning message a few lines earlier.
 --  WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3c

Boot arguments: -v GraphicsEnabler=No nv_disabled=1 IGPUEnabled=1
Edited the config.plist
Intel GFX Injected
Connected via HDMI

IGPUEnabled=1 is not a value for Clover.

Oops. Someones advice, he or she probably didn't realize I was using clover.

Ah well.

I've tried some mixed variations of fixes, including Intel_GFX, displayFIX, add_HDMI

Also tried injecting the IntelGFX aswel.

Good read.
Currently my setup is as follows
UEFI boot, VT-d disabled, CSM disabled, Safe boot disabled, Other OS, Graphics default set to CPU
Quick question, if my GPU was still connected and my monitor is directly connected to the GPU, will it bypass the GPU if I enabled CPU as primary display within BIOS?
Sorry if it's a silly question but I've been finding myself having to reinsert my card a lot, which can't too be good, also, I use a displayport for my monitor 30" dell 3011 (2560x1600)

EDIT****

I'm very pleased to say that I've finally reached the Desktop of ML 10.8.5.

Thanks to the help of Allan, http://www.rampagedev.com/and another kind user on this forum 'uojoumou'

 

  • Downloaded and followed instructions within the Haswell.dmg which can be found here http://www.rampagedev.com/?page_id=50
  • Replaced the fakesmc.kext, config.plist, aswel as the kexts within the Haswell.dmg and added the 'ssdt' specifically for my motherboard onto my USB clover ML install
  • Used the following -s mode commands, which moves all the graphics kext to a BackupGraphics directory (thanks to oujoumou)
     

mount -uw /

mkdir BackupGraphics

cd /System/Library/Extensions
mv NVD*.kext GeForce*.kext AMD*.kext AppleIntelHD*.kext AppleIntelSNB*.kext AppleIntelFramebuffer*.kext /BackupGraphics

sudo rm -rf /System/Library/Caches/*
sudo touch /System/Library/Extensions

shutdown -r now

 

So far I've yet to install clover on the drive itself, graphics isn't at full resolution but still usable.

Will update to see how it all goes.

****UPDATE 

Still can only get 64mb of VRAM


*****UPDATE 2

 

Okay something strange happened.
 

I've got an m.2 drive with Yosemite and a clover EFI installed on it and when I booted it up it went straight to Mountain Lion, with my Asus 970 Strix / Display Port cable running at full 2560 x 1600 resolution.

 

Personally, this works out much better rather than having to use Intel HD @ 1920 x 1024 / HDMI cable / 30" monitor.

Although, I don't think I'll be booting Yosemite for a while as I really have no use for it, not to mention the fact that I've set clover for 'fast' boot  and that I can't mount the EFI via clover configurator (for some reason it just shows a blank efi)

That being said, I'm not running accelerator graphics or any graphics kexts, as far as I'm concerned.
 

This setup works fine for my daily usage, but just a little odd booting the EFI from Yosemite M.2 for Mountain Lion.

It has got me wondering though, if I'd be able to get full graphics acceleration with this card on ML, even being told once before that it's too new and incompatible..

 

hmm   :lol:
