Upgrade from Mavericks failed

[Wildleecher]

It's just funny that I can boot Mavericks from the flash drive that fails to boot the Sierra installer without kernel panic.
But now I am preparing for a journey and have no more time for this, at least for several weeks.

When you're back, you can continue this thread!

I'm back and tried it again with an old version of Unibeast that was still saved somewhere. It failed to install the bootloader, so I installed Clover later. When I try to boot it the result is always the same. Here are pictures of the options and the kernel panic of my latest attempt. The same install stick boots Mavericks without problems, but when I pick Ubuntu or Windows Clover freezes. They are on another harddrive that is formatted in MBR.

There is a KP. Just to double check, you're using Mavericks and want to upgrade it to High Sierra right?

Yes, still the same goal, but it looks like this laptop is incompatible with higher versions of OS X beyond Mavericks.

Provide the EFI you're using!

Here it is zipped.

A few issues here:

The BOOTX64.efi must be in the BOOT directory.
You must have SSDT-EC in the patched directory.
The drivers64UEFI directory contains bogus drivers.
The config.plist is not up to the mark and no quirks are configured.

Assuming your Laptop supports UEFI Boot Mode, follow the guide linked below to create a proper EFI:

Following this guide I finally managed to reach the High Sierra installer and installed a test system on an external SSD. It was possible to boot into it despite of a lot of error messages. WiFi, Sound and brightness didn't work, so I put these kexts into the EFI:
AppleALC
BrightnessKeys
SMCLightSensor
VoodooPS2Controller
IO8021HighSierra
SMCBatteryManager

That was apparently some too many, because I got a kernel panic because of Evoreboot that had been migrated with other files from Mavericks. Even after removing this kext which is incompatible with High Sierra the kernel panic appeared again with the same message. What kexts are really needed?

I can't upgrade from Mavericks before I'm sure everything will work.

I risked installing High Sierra to the internal drive, of course after creating a new backup. But I could not boot into it because of the same error, should have deleted EvOreboot first. After many attempts I was able to boot into the external system again, in save mode, and deleted EvOreboot from the internal drive. Now I can boot into the upgraded system, but only in safe mode. There are still some old kexts to remove.
