[HELP] GPU QI/CI and CPU speedstep need to be fixed

[mohamed3ali]

Hello hackintoshers!

I'v been struggling for a long time (many years in fact) to get the minimum hackintosh requirements working on my laptop:
+Dual boot : OK
+Audio: OK
+LAN: OK
-Display: basic resolution, No QE/CI or native resolution
-External VGA/HDMI: not working
-CPU: speedstep not working
-Sleep/Wake: i'll think about it once all others are fixed

Let start with my config:

• Laptop: Dell Studio 1558
• CPU: i5-520M/HM55
• GPU: ATI Mobility Radeon HD4500 (Ven_ID 1002, Dev_ID 9553)
• RAM: 6Gb

I kept some notes of my experimentations to help me build some experience and avoid getting back to the same errors. So here is what i've tried so far in detail (on both mavericks and yosemite):

1. i used niresh installer, setup works fine using -v to keep an eye wht's going on
2. Format my hdd as MBR with 3 partitions (win10: NTFS, OSX: osx journalised ..., Data: Fat32)
3. the 1st reboot result in error with a welcome voice in the background: Resetting IOCatalogue ...
4. i restarted with: -f -v -x: the same error
5. -v GraphicsEnabler=No PCIRootUID=1: got the setup wizard (bult-in kb/trackpad/usb not working), reboot adding USBBusFix=Yes to complete the wizard with a usb Kb/mouse

Now i'm stuck here, audio + usb + LAN working

To get my GPU recognized i tried lot of kext available on: tonymacx86, OSXLattitude, osx86, insanlymac, hackintoshzone.

Also tried many personalities (the most used for similar GPU are peregrine and shark)
most of them use slightly different model that i suspect cosing the kexts not working (some have different vendor_id).
i even tried adding my vendor/device ids to thr plist file in kext as recomanded in some tutorials but it's not working.

i also tried EDID injection to get the correct resolution without any success.

My goal is getting the latest possible version of osx working with QI/CI (including external VGA) and avoid full power CPU all the time.
For my wifi i'll buy a compatible internal wifi or use a usb adapter once the goal achieved (and thinking to get an ssd).

I'll joint some relevant pics about my hardware in case some one have similar config.

my main needs are:
1/ what's the last OSX i can have on my laptop.
2/ can someone assist to fix my GPU as it's the important part to achieve a functional hackintosh (even sound is not important for me as a web dev/design setup)

I can give any further information if needed, thanks in advance.

NB: i was using chameleon all the time, i would like to use clover if it's better, but till now i never got a successful boot using it, there is too much settings to tweak compared to chameleon.

Merci Hervé for your quick answer.

 

For the distro, it was a quick way to get an installer without having a real mac or working hackintosh behind to create vanilla installer. once all bugs fixed i'll do a clean install based on the best settings i've found.

 

I've seen many posts about this exact GPU and people saying it's working ! 

some examples:

last point about c and p stats: i have no idea how to generate and correctly use DSDT with chameleon, most of tutorials use clover.

i tried to generate a DSDT, compile and add some fixes (including bios reset, power management, ...) than put it to extra folder, but chameleon seen to not use it as theses bugs are still there.

It's 4570, here is what i got with clover settings (see joined photos).

 

I've red that mine is supported too ans others are reporting successful results. But it was very old posts and no one is answering to get more details how the achieved it.

 

I would like switch to cpu integrated gpu but can't do it. My knowledged about dsdt are vary limited (my bios don't allow to disable discrete gpu)

I'v already tried many of them in the past with this exact clover config.

I suspect that this error is not event related to my graphic card as i can't till now boot correctly with clover.

 

tomorrow i'll switch back to chameleon as it allow me at least to boot osx and make sure i have the AMD4600 kext  i try all framebuffers i find inside.
