v8558 Posted August 24, 2014 Share Posted August 24, 2014 Hello, I am somewhat new to this. My build is a Gigabyte GA B75m d3h, and I have an i3 3245 with HD 4000 graphics installed on it. I want to use integrated graphics, and have gotten to the point that the kext loads in Mavericks, and is recognized as "Intel Graphics 4000 with 1024 MB". However, the graphics are still really choppy, and I have no idea what I'm doing wrong. Any help is appreciated. Thanks! Link to comment Share on other sites More sharing options...

v8558 Posted August 26, 2014 Author Share Posted August 26, 2014 Hi, I really need help with this, I have tried countless times, and installed many times with MyHack. I cannot boot into the system, because I get the IOBluetoothHCI controller missing error, and then DRMStatus error. When I boot in with safe mode, my system info shows that I have an Intel HD 4000 GPU with 1024 MB. How can I get to boot normally? All help is appreciated.

miqlas Posted August 26, 2014 Share Posted August 26, 2014 You told before, that you was able to boot to the GUI. Have i understand it correctly? If yes, then your GPU driver works. The choppiness can be a symptom of the CPU Power Manager problem. It means maybe you need an own SSDT, or your bootloader can generate the P and C states for you. How to check your P and C states: - Boot to the GUI. - Install the IntelCPUPowerManagementInfo.kext (you can found it in the attachements.) - Fix the premissions with KextWizard (google it, it is handy) - Reboot. - Run something CPU power hungry (3d game, a CPU benchmark, or something like this) - Open Your Terminal and run this command: cat /var/log/system.log | grep "AICPUPMI:" It will print an output like this: Aug 26 20:21:22 YOURCOMPUTER kernel[0]: AICPUPMI: CPU P-States [ 8 12 13 16 17 18 19 20 22 25 27 ] If You can see many numbers at the end of the line, then your P-States generated correctly. If you see just 1 or 2 number, then you need to correct your SSDT or set your bootloader to generate it on the fly for you.

v8558 Posted August 26, 2014 Author Share Posted August 26, 2014 Thanks for the info. I was able to get to GUI at one point, but now I cannot, and get stuck at iobluetoothhcicontrollerstart error. Is there any way to get back into the system with proper graphics? Edit: I am able to see the 1024 MB of ram for the intel hd graphics 4000 when I am in safe mode, but i can't boot into normal mode Thanks in advance.

v8558 Posted August 28, 2014 Author Share Posted August 28, 2014 Does anyone else have any ideas about this? I have tried all the values of IntelCapriFB. When I boot into safe mode, I see the the 4000 kext and the CapriFB kext are loaded, but not the IntelFramebufferSNB kext. In safe mode, it shows that I have 1024 MB of video ram for the 4000. However, I get stuck at the [iOBluetoothHCIController] start error when I try to boot in normally. I have been trying everything for days and have had no success.

The_Village_Idiot Posted August 30, 2014 Share Posted August 30, 2014 Either disable vt-d in BIOS or add dart=0 in ur boot flags Link to comment Share on other sites More sharing options...
