Moderators Jake Lo Posted June 19, 2015 Moderators Share Posted June 19, 2015 So you were able to reinstall but won't boot afterwards? Link to comment Share on other sites More sharing options...
aviepic Posted June 19, 2015 Author Share Posted June 19, 2015 I reinstalled, tried removing the file you told me to and used vanilla AppleIntelFrameBufferAzul.kext, but the QE/CI Acceleration did not work. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 19, 2015 Administrators Share Posted June 19, 2015 That's quite normal, but can you confirm you reached the Yosemite desktop? You now need to finalise tuning to obtain graphics acceleration. You could do that either by faking HD4600 Desktop or by patching the graphics kext.

aviepic Posted June 19, 2015 Author Share Posted June 19, 2015 Ok so how would i do that? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 19, 2015 Administrators Share Posted June 19, 2015 Jake has posted several posts about the method to fake desktop HD4600 GPU (id 0x0412) with kexts. I'm sorry I don't have links at hand but you'll find them in the guide section or through the Search engine. You can also consult my E6440 Mavericks/Yosemite guide which fully details the methods I followed to patch the Azul frame buffer kext to support the mobile HD4600 GPU (id 0x0416). The exact same principles will apply to your HD4400. PS: afaik, Chameleon boot parameter "IntelAzulFB=xxx" is ineffective with Yosemite. With my E6440, it worked perfectly with Mavericks, never with Yosemite. I had to patch the DSDT. Link to comment Share on other sites More sharing options...
aviepic Posted June 21, 2015 Author Share Posted June 21, 2015 I can't seem to find it, is it possible for someone to post a link to it? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 21, 2015 Moderators Share Posted June 21, 2015 Start reading from this post, resolved for the same model. or Try this by Mirone. Just run Patched_IntelHD4400_v2.sh. Search for this in the DSDT.aml with MaciASL.app Return (Package (0x0A) { "device-id", Buffer (0x04) { 0x12, 0x04, 0x00, 0x00 }, "AAPL,ig-platform-id", Buffer (0x04) { 0x06, 0x00, 0x26, 0x0A }, "hda-gfx", Buffer (0x0A) { "onboard-1" }, "model", Buffer (0x0E) { "Intel HD 4400" }, "AAPL00,DualLink", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 } }) replace with this Return (Package (0x06) { "AAPL,ig-platform-id", Buffer (0x04) { 0x06, 0x00, 0x26, 0x0A }, "hda-gfx", Buffer (0x0A) { "onboard-1" }, "model", Buffer (0x0E) { "Intel HD 4400" }, }) Link to comment Share on other sites More sharing options...
aviepic Posted June 21, 2015 Author Share Posted June 21, 2015 Trying it right now, I will get back to you soon Link to comment Share on other sites More sharing options...
aviepic Posted June 21, 2015 Author Share Posted June 21, 2015 Same thing happens using both methods, it seems that AppleIntelFrameBufferAzul.kext is causing it because if i boot without it by removing it, I can boot without QE/CI. Here is a vid of what happens, similarly when i boot without verbose, the screen flashes and stays on the Apple loading screen. I tried with flags "-v -f IntelAzulFB=12" "-f IntelAzulFB=12" "-f" and once without flags but same results. Thanks IMG_0865.MOV Link to comment Share on other sites More sharing options...
