mpalomba3 Posted June 16, 2015 Share Posted June 16, 2015 Ok so I've got the installer booted using the chameleon boot loader. I install Yosemite and then try to boot into it using the USB drive. It hangs on Sound assertion. I was told that this isn't an audio problem but a graphics problem. Anyone have any ideas? Graphics acceleration seemed to be active in the installer so I'm not sure why it is an issue now. By the way, I can't boot in safe mode either. I have the modified graphics & frame buffer kexts in S/L/E on the install drive. I'm going to try moving them to Extra/Extensions and see if it helps.

Moderators Jake Lo Posted June 16, 2015 Moderators Share Posted June 16, 2015 How'd you install the kexts to S/L/E? Did you installed to the Installed drive or only on the Installer? Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 16, 2015 Share Posted June 16, 2015 Ok so I've made some progress. When everything is finished loading the screen flashes white like it would when OS X is finished loading then it goes pitch black and then the backlight comes on but no image on the screen. Any suggestions? Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 16, 2015 Share Posted June 16, 2015 How'd you install the kexts to S/L/E? Did you installed to the Installed drive or only on the Installer? I installed them on the installer flash drive. I haven't been able to boot into the system yet. Once I moved them to Extra/Extensions on the installer flash drive the computer almost boots into OS X, it shows the white screen for half a second, then goes black with the backlight on Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 16, 2015 Moderators Share Posted June 16, 2015 Reboot to the USB Installer. Launch the Terminal. Copy the modded kexts from your Installer to the Installed drive (SLE) and reboot. Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 17, 2015 Share Posted June 17, 2015 How do I do that? I tried doing it from windows using Paragon HFS+ then using the installer to repair drive permissions but upon rebooting into the actual OS it did the same thing. I also tried what was mentioned in the guide here, go into terminal then enter a few commands then repair permissions and reboot but when I did that OS X kernel panicked as soon as i tried to start it. It wasn't on a specific kext either, it was on the CPU I believe. Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 17, 2015 Share Posted June 17, 2015 I think I am missing a boot flag or something. I boot with: GraphicsEnabler=Yes -f -v dart=0 USBBusFix=Yes. I also tried GraphicsMode=1024x768x32 but it didn't change anything so I don't use it. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 17, 2015 Moderators Share Posted June 17, 2015 Boot to USB Installer. Launch terminal, run diskutil list ( to locate you volume names) cp -R /Volumes//System/Library/Extensions/AppleIntelHDGraphics* /Volumes//System/Library/Extensions Reboot Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 17, 2015 Share Posted June 17, 2015 Thats exactly what I did but it didn't work. I am trying Mavericks now to see if I can get that to actually boot. If I can I will try Yosemite again. Link to comment Share on other sites More sharing options...
mpalomba3 Posted June 18, 2015 Share Posted June 18, 2015 I just tried that on the Mavericks install and it does the same thing. Immediate kernal panic when I try to boot. I'm starting to think that the laptop just cant run OS X. I am no noob to hackintoshing but this laptop is giving me a lot of trouble. Link to comment Share on other sites More sharing options...
