aviepic Posted June 17, 2015 Share Posted June 17, 2015 Hey guys, I have a Dell Latitude e7240 and I am trying to install Yosemite on it. My specs are: i5-4310u HD4400 8GB Ram 32GB SSD(for osx) 256GB SSD(Windows) After I install I can successfully boot without QE/CI Acceleration. When I try to install the AppleIntelFrameBufferAzule.kext my laptop fails to boot after. I used the flags "-v -f IntelAzulFB=12" and I also tried only "-v -f" but the boot keeps getting stuck. Before it freezes up, the screen flashes once. I used this guide: (https://osxlatitude.com/index.php?/topic/7478-dell-latitude-e6xxxe7xxx-yosemite-install-guide/) and I used the kexts and everything given in post four. It would be great if someone could help me out with this! Thanks Avi Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 18, 2015 Moderators Share Posted June 18, 2015 Try booting with the USB Installer and then select your Installed Drive. Make sure you don't have anything else connected. Link to comment Share on other sites More sharing options...
aviepic Posted June 18, 2015 Author Share Posted June 18, 2015 It seems the OS is loaded but the graphics are not displaying. For example after i verbose boot, when it 'freezes up' the OS is able to detect when USB hardware is connected to the computer and like when i click like f8 or something i can hear sounds from the OS. I just can't get graphics to work unfortunately Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 18, 2015 Moderators Share Posted June 18, 2015 Boot with -x -v -f Once log in, then you could try fixing the graphics issue. Link to comment Share on other sites More sharing options...
aviepic Posted June 18, 2015 Author Share Posted June 18, 2015 I tried booting into safe mode but it does not boot, same thing happens. It shows XCPM P-State issue or something I don't know if this is exactly relevant or not but thats one of the last lines of code that shows up before it freezes.

Moderators Jake Lo Posted June 18, 2015 Moderators Share Posted June 18, 2015 Do you have the correct version of the patched Kernel replaced on the Installed drive? Attach a screenshot, it would be more informative. Link to comment Share on other sites More sharing options...
aviepic Posted June 18, 2015 Author Share Posted June 18, 2015 Ok and I have the correct kernel i think, I use the Haswell 10.10.3 patched kernel Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted June 18, 2015 Moderators Share Posted June 18, 2015 Remove SSDT.aml. Not for your CPU Try also booting with the USB Installer and restore the vanilla FB to the Installed drive. Link to comment Share on other sites More sharing options...
