pastrychef Posted July 15, 2017 Share Posted July 15, 2017 @Jake Lo Hi. I was trying to see if the High Sierra beta would work and encountered a kernel panic when booting (please see attached images). How can I fix this? Thanks in advance!

Moderators Jake Lo Posted July 15, 2017 Moderators Share Posted July 15, 2017 Drop ACPI Table BGRT. You can do this in the Config file where you already have DMAR dropped. Link to comment Share on other sites More sharing options...
pastrychef Posted July 15, 2017 Author Share Posted July 15, 2017 Hi! Applying BGRT helped my get past that panic. Now, the progress bar under the Apple logo appears and loads half way (previously, the progress bar never appeared), then the laptop reboots. Below is the best video I managed to capture with my iPhone... IMG_7636.MOV Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 15, 2017 Moderators Share Posted July 15, 2017 what process did you use to create the installer? Link to comment Share on other sites More sharing options...
pastrychef Posted July 15, 2017 Author Share Posted July 15, 2017 I used Terminal and the "createinstallmedia" in the installer to make USB installer. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 16, 2017 Moderators Share Posted July 16, 2017 Ok, install Clover and use the same bootpack for Sierra, just add the additional drop table BGRT and generate a new SMBIOS with the latest Clover Configurator 4.45. Try booting to different USB ports. For my E7450, I'll get encounter "Still Waiting for root device". Normally this will failed on older builds, but for HS, it'll continue booting. A new message shows "USB device 0984830114D00000 - will be reset!" After that a bunch more messages appears and eventually a grey screen, the the installer will appear. Continue the normal installation process. Link to comment Share on other sites More sharing options...
pastrychef Posted July 18, 2017 Author Share Posted July 18, 2017 Sorry for the late reply... Some things I have tried: I tried redoing the SMBIOS while keeping BGRT. I tried both MacBookAir7,2 and MacBookPro12,1 SMBIOS. I tried using Lilu.kext and IntelGraphicsDVMTfixup.kext. I tried booting from an SSD with High Sierra beta 2 already installed. They all resulted with the same reboot issue. The same config.plists all boot my existing 10.2.5 system perfectly. Thanks again for your time. I wish I could buy you guys a few beers...

Administrators Bronxteck Posted July 19, 2017 Administrators Share Posted July 19, 2017 do you have latest clover from source? same for lilu and it's plugins read the docs for LILU and plugins because you need to boot them with beta boot flags Clover_v2.4k_r4119.zip 1 Link to comment Share on other sites More sharing options...
pastrychef Posted July 19, 2017 Author Share Posted July 19, 2017 Yes!! Adding "-lilubeta -igfxbeta" was what was needed and, yes, I had already upgraded to the latest Clover. I feel so foolish for missing something so obvious. Thanks so much to both of you for all your help!!! Link to comment Share on other sites More sharing options...
pastrychef Posted September 26, 2017 Author Share Posted September 26, 2017 Just wanted to let everyone know that I upgrade from Sierra to High Sierra on my laptop without any problems. Here's what I did prior to the update: 1. Updated to latest version of Clover. 2. Placed High Sierra compatible version of apfs.efi in to /EFI/CLOVER/drivers64UEFI/. 3. Updated to latest versions of FakeSMC, FakePCIID, Lilu. Then, I just updated to High Sierra from App Store. Thanks once again to everyone here!!
