yes i followed the guide to the letter and i checked my bios settings and they are the same, i have a copy of yosemite i can try and use, using clover or something if i have too

ok just added them and tried to boot and it did not work same errors as last time

will try in a few minutes

hey everyone, i am trying to install el capitan 10.11.3 on my d830 with nvidia 140m and 1490 wireless and 2ghz core 2 duo with 4gigs of ram, i followed the guide for the d630 but used the files for the d830 but am getting the following errors when i try to boot the installer. the usb was setup on a mac book air running 10.11.3

Is there anything else I can do to remove the skipping video and overall sluggishness?

yeah i dont know where the kexts came from or how i got them ok so far no black screens except if i close the lid and open it back later i have to turn it off and back on again and i also have sluggishness when watching youtube or the like and i was not like that before

well i went ahead and fully erased the hdd and started over, however i did get stuck during install where it kept going back and forth between less than a minute and about a minute left and it did that for about 2 hours and finally it started moving and finished but it said the install failed but i was able to reboot into it anyway. so i went ahead and applied your fixes and while myfix was running i got a black screen and had to shut down and am not sure if that fixed it or not, still waiting to see, i also unhooked my bluetooth module and that seemed to help the install some, not sure what model it was or if it was giving it issues but i will take it out later and post the model EDIT forgot to add i do not have audio, where do i get the kexts for that or should i use EDP for that?

i did not edit the dsdt, all i did was use a virtual machine and a 10.9 dmg i downloaded and created a myhack install with the downloaded pack for the d830 EDIT how do i get rid of NullCPUPowerManagement? also everything is stock from a normal install, i did not even run EDP at all or tweaked anything EDIT 2 i forgot to add i was trying to fix the audio and now can no longer boot into normal mode only safe mode, i will just do i full erase and reinstall using the files posted here and see how far that gets me i think this is what is causing me to not boot into normal mode

ok i got the new kexts installed and ran myhack and so far stuff seems ok, still got that black screen on boot sometimes not sure what that is or how to find out and i also no longer have audio EDIT i have also attached my extra folder Extra_backup.zip

Yeah it was not asleep I'm wondering I might be using the wrong USB drive or something

Awesome I haven't done the kexts yet but will tonight, will they fix the issue of the screen going off and not being able to wake it up by moving the mouse or using the keyboard? That same issue came up during reinstall and it had been sitting there for two hours before that with 7 minutes remaining not moving at all so I had to shut down and it still booted

ok so i ran the install over my old install and i am back up and running, now to make sure i do this correctly i place the kexts above into /E/E and run myhack and select myfix and that will install them correct? edit forgot to ask why is the folder name for the kexts above called D830n?

Will do it tonight and report back tomorrow

i dont think that works when booting to usb does it? either way i have to do a full reinstall cause of not being able to boot in normal mode or safe mode EDIT question is this the same as my issue? https://osxlatitude.com/index.php?/topic/7548-ga-z97x-ud5h-i5-4460-clover-yosemite-kernel-panic-unable-to-find-diver-for-this-platform-acpi/

Would I still need to change the smbios and the other thing even if I were to include the kexts above in my extra folder if I were to reinstall?
