[Solved] Apple Logo boot loop after MultiBeast updates

[Nyak]

I've been struggling with network issues on my Hackintosh for over a year now, and in my troubleshooting I decided to update my kexts and drivers. After doing so and restarting, I get a kernel panic boot loop on the Apple logo. I just finished updating to Sierra, is there a way I can solve the problem without reinstalling?

 

[vulgo]

Some boot flags to show more information or otherwise aid in booting:

Disable graphical boot, verbose output

-v

Don't reboot on panic

debug=0x100

Safe boot, boot without third party kexts and rebuild kernel cache

-x

Force loading kexts, don't use pre-linked kernel cache

-f

Save Clover pre-boot log to /efi/clover/misc:

Press F2 at boot menu

I ran it with all the boot flags in addition to dart=0 and nvda_drv=1 and somehow it still went into a boot loop. I didn't manage to back up my OS drive before I updated my kexts so I still have sensitive data I need to preserve, too.

Remove dart=0 and nvda_drv=1, try only with these and also post the pre-boot log.

-v debug=0x100

and/or

-x -v debug=0x100

without more information there is not much hope for help. Your data will be recoverable from a secondary macOS installation or a linux live distro btw.

Not a very good idea to remove dart=0 if VT-d is enabled in the BIOS.

Not a very good idea to remove dart=0 if VT-d is enabled in the BIOS.

Will make no difference.

    // Override the mapper present flag is requested by boot arguments.
    if (PE_parse_boot_argn("dart", &debugFlags, sizeof (debugFlags)) && (debugFlags == 0))
      removeProperty(kIOPlatformMapperPresentKey);
    if (PE_parse_boot_argn("-x", &debugFlags, sizeof (debugFlags)))
      removeProperty(kIOPlatformMapperPresentKey);

Will cause Kernel Panic without dart=0 if VT-d is enabled in the BIOS not a good idea.

It is fine to leave dart=0 in the boot flags.

I tried it with the boot flags you reccommended, still gets stuck after the ACPI sleep states. Here's the verbose log if it helps.

What about the pre-boot log? As there is no panic with safe boot, probably more helpful to upload your EFI folder (minus the themes, but with preboot.log - press F2 at boot menu to save to /efi/clover/misc)
