ATI cards stuck at rainbow cursor Yosemite 10.10.1 - Hackintosh Yosemite - Hackintosh Zone Jump to content

Recommended Posts

ok here goes I've been building hackintoshes for a while both amd and intel nvidia and ati right now im typing this on a asus a55a (specs: i7 3610qm 8gb ddr3 so-dimm ram intel hd4000 graphics) and it work flawlessly i recently gave my friend my hackintosh desktops because he had no computers at all so i gave him both and converted one back to windows one was a amd 6 core and the other an i5 dual core both worked flawlessly and both were using the Gainward gtx 460 gs 2gb ok now my problem:

ok installation on both boards is no problem its after the installation i see the boot screen with the bar and the apple or hackintosh zone logo then a grey screen with a rainbow cursor i have tried on both boards and both graphics cards and same issue every time i have been at this now for well over a week day in and day out if i back up all graphics kext during installation i can boot without using -x but as soon as i install any ati driver for those cards its back to the same way once again i have tried different installations every boot flag under the sun every kernel i can find but its defiantly a graphics driver issue please someone tell me there is a solution to this

heres a list all the parts i have

PROCESSOR: AMD 8350 BOX PROCESSOR ------ AMD 8350 TRAY PROCESSOR

MOTHERBOARD: ASUS M5A97 EVO R2.0 ---- GIGABYTE 990FXA-UD3

GRAPHICS CARD: GIGABYTE 2GB ATI HD 7870 ----- 2x 1GB XFX HD 5770

RAM: 24gb CORSAIR VENGENCE 1816MHZ DDR3 ------ 32GB GSKILL ARIES 1600MHZ DDR3


THIS IS NOW SOLVED :) :) :) :)

first of all thanks everyone ( @Simone Rucci, @Niresh) who helped on this post i couldn't have made this happen without your help this will solve you beach ball spinning infinite grey/white screen crap ok i got this working the procedure is as follows on two different boards

asus m5a97 evo r2.0

gigabyte 990fxa-ud3

and two different graphics cards

gigabyte ati hd 79870 2gb

xfx hd5770

my processor is a amd fx 8350
32gb ddr3 gskill ram

I AM ALSO USING GPT

i can now easily play might and magic x legacy on full graphics settings

ok i used a certain kernel and the stock graphics drivers if you wish to change that it may or may not work

ok procedure you now need to have kext wizard handy

you need to head over to here for the AMD kernel

http://www.insanelymac.com/forum/index.php?app=core&module=attach&section=attach&attach_id=157955

inside that file is the kernel and the system.kext

now you need to go over to here to grab the other two kext IOPCIFamily.kext + AppleACPIPlatform.kext for yosemite

http://www.insanelymac.com/forum/files/file/354-amd-replace-kext-for-yosemite/


you will also need amd webkit patch

http://www.insanelymac.com/forum/index.php?app=core&module=attach&section=attach&attach_id=154087

now i want you to place all kext on the desktop
if you have backed up your graphics drivers during or after the install you should be able to boot with just

npci=0x2000 PCIRootUID=1 -v

if not you will also need to add

-f -x

now once you are at your desktop you need to move the kernel over to System/Library/Kernels
so rename your original kernel to kernel.backup1 then overwrite it with the new one

you will then open up kext wizard and use the install pane to install

system.kext
IOPCIFamily.kext
AppleACPIPlatform.kext
(also if you backed up your graphics drivers nows the time to reinstall them)

then i want you to keep kext wizard open and install the amd webkit patch after installation has finished go back to kext wizard and repair permissions (click both boxes on the bottom half)

then reboot some of you still may have to use -v and -f

i have mine booting with full acceleration
without -f -v

I have also posted the guide

Here i linked the full procedure:https://www.hackintosh.zone/forums/topic/5637-installation-issues-with-amd/page-2#entry21521

For what concernes the set-up, i suggest you to use the gigabyte mobo (with arguments pcirootuid=1) and the gigabyte video card, ram and CPU doesn't matter.....

Once you finished the installation, follow my instruction in the link.... Pretty sure it'will work like a charm ;)

first post in this page for kernel and system kext, 5 post after (Carlo_67's post) kext to replace, also download and install new niresh's amd webkit

 

where to put all this files:

 

S/L/Kernel ------> kernel

S/L/Extension --------->  System and the 2 other kext

 

Then reboot in safe mode, install webkit and add -f (ignore kernel chache) in boot arg.

Reboot normally

    • guys please help me .....................im stucked at apple logo while installing im using hp laptop core i5 7200u 6gb ram amd radeon R5 M430
    • I have working audio, graphics and network on this 10.13  Now store has sent me "security update" which I believe is 10.13.3.  Has anyone done this via store? What do I need to do before I install it? I have issues loading EFI so have to always manually mount it (Clover configurator and EFI mounter both fail) but using terminal and command "open /efi" I am able to mount and make changes to my config.plist too.   
    • Hi guys, I try to install Mac OS X Yosemite on my computer, but... i get stuck at the logo (when i boot it) + i see a bar, who won't charge. Can you give me a solution?   Processor: Intel(R) Pentium(R) Dual  CPU  E2180  @ 2.00GHz (2 CPUs), ~2.0GHz Memory: 2048MB RAM    User DPI Setting: Using System DPI  System DPI Setting: 96 DPI (100 percent) Display Card name: NVIDIA GeForce 210  Manufacturer: NVIDIA Chip type: GeForce 210 DAC type: Integrated RAMDAC  
    • Just to Add I used My windows machine with TransMac to wipe and build the install (including USB). I only used the clover installer I forgot that it could switch to chameleon.
