Hello community,
Please lend me a hand with the following issue, I spent a while trying to fix this on my own but cannot:
Dell Latitude e7250
Broadwell
Intel Core i7-5600U
Intel HD Graphics 5500
Firmware A17
UEFI/BIOS settings correctly set (as working with sierra previously)
Previous state: Running MacOS Sierra on the internal SATA M2 SSD without any issues
Current state: Wiped the internal SSD with dd, empty and no partition table yet in preparation of fresh High Sierra install
Steps to create boot medium (all the official steps from guides):
1) Used Apple provided command line tool for creating boot media
2) Installed the latest (official, no fork) Clover bootloader
3) Merged the generic EFI folder EFI_4439.zip
4) Updated to newest lilu 1.2.3
5) Installed specific High Sierra bootpack
5a) Tried bootpack E7450_HD5500_Only_A17_HS.zip from https://osxlatitude.com/forums/topic/8514-dell-latitude-e7450-clover-uefi-only/?tab=comments#comment-76261
5b) Tried bootpack E7450_HD5500_Only_A19_HS.zip from same source as above
5c) Tried bootpack E7250_A17.zip from https://osxlatitude.com/forums/topic/10318-solved-e7250-unable-to-boot-high-sierra-installer/?tab=comments#comment-76635
The install USB thumbdrive is currently using the clover config from 5c and the bootpack from 5c.
Leaving out step 5 altogether leads to a kernel panic like here: https://osxlatitude.com/forums/topic/10318-solved-e7250-unable-to-boot-high-sierra-installer/?tab=comments#comment-76617
With step 5a, 5b, and 5c the installer just stops and hangs at a random point during boot (after selecting the installer partition with Clover), always around 3 seconds after choosing the installer partition in clover. It is not a kernel panic, the verbose mode just stops scrolling and hangs there, the CPU gets hot after a few minutes with the fan spinning and there is nothing that can be done other than turning it off.
I narrowed the issue down to the ACPI/patched folder, when it is empty I get a kernel panic and when I fill it with the files from the bootpacks, the hang occurs.
It seems that for my specific hardware, re-patching of the native files (DSDT/SSDT) might solve the problem. I have attached the origin folder after dumping the files with F4 in Clover. Now I know how to do basic troubleshooting, and I have learned a bit from having 3 other Hackintoshes at home all working fine after crying a lot. But I have never patched the native files myself. Can you refer me to a guide on how I can do that? Or could you patch them for me, if you are willing to? I do not know how time consuming that is - I saw a guide earlier this morning but can't find it again now.
I am not sure if my assessment of the problem source is correct though, perhaps I need to use an older High Sierra installer like 10.13.3? I really don't know and I could use your help. Thank you very much for your time!
