When you get this error 77, redo the last commands (touch + kextcache). Failing that, opt for: sudo kextcache system-prelinked-kernel

Hmm, it's as if your graphics are not initialising. Check that you have the DSDT in its expected place and that it contains the appropriate SNB layout-id. Make sure to boot with: Enoch flags & parameters KernelBooter_kexts=Yes -f -v Extra folder copied to your USB installer Patched AICPUPM kext in place (/S/L/E) or NullCPUPM kext in /E/E

Boot in verbose mode (-v flag) to try and grab where the boot process hangs. But if you have same hardware + same BIOS version + same BIOS settings, I'm failing to think of anything specific.

Afaik, you only patch the Capri FB in order to gain specific video output(s) such as HDMI and/or VGA for instance. I think this was mentionned in previous posts. HD4000, like HD3000 before it, has no built-in dedicated VRAM; as such, for memory, these iGPU use computer's RAM.

Check that your HDD mode is set to AHCI in the BIOS settings. OS X does not usually support modes such as RAID. One other thing you may try when you obtain the "waiting for root device" is unplug then replug your USB installer key.

You need the patched AppleHDA kext in /S/L/E + the codec specific AppleHDAxxxx kext in /L/E. If you have Clover, you can simply add the on-the-fly AppleHDA patch to your config plist.

I could not say whether your friend's statement re: VGA control is true or not, but VGA output off IvyBridge iGPU is not usually supported OOB under OS X and requires FrameBuffer patching. Since you run on your integratedHD4000, I would expect you need the VGA patch applied to your Capri FrameBuffer. You'll find details of the patch here. Identify your active HD4000 layout-id (0x0166xxxx), then experiment with the described VGA patching possibilities until you hopefully find the value that works. Keep a backup of the vanilla Capri FB of course!

KP=Kernel Panic -> means system crash.

Check that you have: 1) the Extra folder at USB installer root and that it contains the kernel + org.Chameleom.Boot + smbios plists & the correct kexts in Extensions subfolder (FakeSMC, VoodooPS2Controller and NullCPUPM being mandatory to begin with) 2) that the kernel.plist file does contain the parameter KernelBooter_kexts set to Yes

You may look here. Very complete and up to date general guide afaik.

A few things to do on your USB installer: remove the SSDT provided in the bootpack from /Extra (it's for a i5-3340M and unsuitable for your i5-3320M) if it's missing, add the attached NullCPUPM kext to /Extra/Extensions folder reboot NullCPUPowerManagement.kext.zip

BIOS version and CPU model? Post a (1024x768) picture of General->System Information BIOS page.

You've got your answers above. Please read them.

Again, please read and follow the guide! The guide clearly states it applies to the E6230 fitted with i5-3340M CPU (CPU-specific SSDT in the bootpack). For other CPUs: Did you read that too?

As stated in the guide: It'd please me if you could read the guide with a little more attention... I made every effort to post an orderly step-by-step procedure and every step is required.

As stated in my previous above, USBInjector is of no help for your issue. It's your DSDT...

You might have been, yes... I'd restore them if I were you. Looking at the DSDT (dated May 2016) you posted on May 24th, one will notice that none of your EHCx or HDEF devices have the usually required _DSM method that defines power settings and is required for sleep. I would suggest you add this to the DSDT devices. You'll find details of the code all over the forum. Here for instance. If, after that, you still have issues like instant wake, you may adjust the _PWR methods for those given devices. All according to info posted by Rehabman on his blog. Re: USB injector, it's used to get USB ports to work (be recognised), not really for sleep or wake. The SMBIOS you use must match the model configured in the USB injector and the ports specified in the injector must match those defined in the DSDT... The injector kext posted above would gain by being substantially optimised (read: remove all unnecesary entries). Look here for details re: creation of an adequate and optimised USB injector.

Please follow the guide more carefully... NB: Go easy with size when it comes to picture attachments!

Last update: 15 Nov 2020 Here are BIOS settings that are known to work on the E6230 (Intel Ivy Bridge CPU with Intel HD4000 graphics) under Mavericks, Yosemite, El Capitan, Sierra, High Sierra, Mojave, Catalina and Big Sur.

My guide is applicable to BIOS in legacy mode. Ensure you've setup your BIOS according to the recommended settings. No merge for the Extra folder. Copy it "as is", replacing any existing folder.

Tried this guide?

VGA output is supported OOB throughout the D630/D830 nVidia models. Just plug and play... You can search the forum (and its archive) for old threads related to VGA output on the D Series; the matter was quite extensively discussed between 2011 and 2013.

Unrelated to Dell Latitude D8xx, so topic moved to Intel-based systems section.

I edited and compiled the above DSDTs with MacIASL, make sure you have a recent version of the app.
