7. then the screen turns white with a mouse, then it turns black and stays as is.

This is my first time hackintoshing, I don't know much about what I'm doing. Any help please? What does this error mean? why it shows up? how to fix it? :|

Hi kevin G,

First of all welcome.
Please have a look at the following topic: http://www.insanelym...ort-tonymacx86/

About point 6. It's a warning, not an error, no need to worry about it :)

Any other graphics besides the HD 2500? Have you tried any other strings so far?
What happens when you boot with the following options: -x -f -v?

Thanks Lejenk for your reply,
No there's not any other graphics, just the HD 2500.
When I boot with -x -f -v I get the same warning, then it boots successfully in safe mode.
And when I view the System Report panel > Graphics > it shows graphics card is HD 4000.
Then tried again to boot Normally, but it fails again.

I also tried this string:
ig-platform-id: 01620005, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

And this one from here (and changed Shared Memory for this one to 64M):
ig-platform-id: 01660003, FB Memory: 64MB, Pipes: 2, Ports: 2, FBMem: 2
7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31


But all with the same results ... :(
Any suggestions?

Play chess, test the screensaver, does it work?
Then you are fine.

I have read about the 2500 using the 4000 kexts, and showing up as it.
All i know about it, sorry.

I tested it by playing videos, but it doesn't work.
Maybe I should give up on it.
I'll buy a separate Graphics Card, if you have any recommendations for me please share it in this new thread I just created.
Thanks for you help Lejenk :)

For some unknown reason the HD2500 doesn't work for everyone...

Upload your DSDT and I'll try to patch it for the HD2500.

Yep, I think you're right Dr.Hurt, and this unknown reason made a lot of people like this >> :wallbash:
My DSDT file is in the attachments Dr.Hurt.

I did some investigations with the help of a few HD2500 owners and found out that the driver is assigning the wrong the DisplayPipe to the monitor. It seems very random though. It works perfectly for some and fails for others.

I believe this might require hex editing the kext to fix, which, unfortunately, is beyond my scope.

Anyway, here are two patched DSDTs for you. Use them with 32MB vram, GE=No, and delete any strings you're using.

Try with HDMI and DVI to see if it makes a difference. If it doesn't work you'll probably need to get a discreet GPU.

PS. Don't worry about that power management error. It just means your CPU is not recognized (since it's not used by any real mac).

I've tried both DSDT files but unfortunately, they didn't work. I'll just buy a new card.
However, thanks a lot for your help Dr.Hurt or (Jazaka Allahu Khairan), lol :)
