2. Let the installer run, and reboot.
3. Once the installer reboots you need to boot off the USB installer, let the installer load. Once the installer loads select Terminal from the Utilities menu.
4. Once Terminal loads enter:
sh "/Volumes/HighSierraAMD for Radeons 2/AMD/setup_run" To do it without quotes press tab after typing HighSierraAMD and it will autofill the name then input /AMD/setup_run
6 . Once Pre-Install is done choose 11 to reboot.
7. Now you want to boot from the Boot macOS Install from YOURINSTALLPARTITION.
8. On boot the installer will run again and copy files, could take some time, once through it will reboot again.
9. Boot off the USB installer again and when the UI loads select Terminal from Utilities menu. When Terminal loads enter the above command again to start the install script.
10. When the menu loads choose Option 2 for Post-Install. Enter you hard drive name and Y for all the questions.
11. When finished Choose 11 to Reboot.
12. Now, using the USB, boot off your macOS partition and a mini install may or may not occur that will last a short time and boot you to desktop. I had the mini install on my install to my 10.13.1 but not to my upgrade of 10.12.6.
13. You're done. Use your eyes and pay attention and you'll be ok.
14. I had issues dual booting windows and my high sierra on the same drive, I had to delete the window partition to let the install happen. I've asked Shaneee about this and am awaiting an answer.
I have an Clover based installer for Radeon cards, PM me and I'll give you the links. Have your specs in your signature as this won't work for NVIDIA. Included on the dmg is a Clover Files folder you'll need for PostInstall.
To begin use Transmac to restore the HighSierraAMD.dmg file to a USB drive, the USB drive needs to be at least 8GBs in size. This tutorial by Shaneee covers using Transmac to restore dmg images to USB: viewtopic.php?f=24&t=1213 Once you have the image restored you want to boot off the USB drive. You want to select HighSierraAMD to begin. If you get a Waiting on Root Device message, move the USB to a different port for a few seconds to see if the install continues. If it does not then keep moving ports until it does.
Set your SATA ports to AHCI
Enable USB Legacy support and EHCI handoff
Disable your Serial Port
Enable CSM and UEFI for Hard drives and USB devices
Set Secure Boot to Other OS
Just for postinstall for now, instead of entering start you would enter:
Select you USB drive and hit enter
Choose HighSierraAMD from the menu
Click the next button to load the installer
Click Utilities from the menu and select Disk Utility
Select your drive from the list on the left you want to install to
I already have a full drive so I'll select my old High Sierra partition and click the - button below it. This will remove and redistribute the space to the next partition. Click Apply.
You'll see a dialogue going through removing and resizing the next partition.
Select the Partition button again to create your new HighSierra partition. Now click the + sign below the circle to create a new partition.
Give the partition a name, don't use spaces, and then click apply.
Click Partition to create the new partition.
The partition create dialog will open showing resizing and creating the new partion. When it's finished click Done.
You'll see your new partition show up in the left side list. You want to make sure it's formatted as GUID with extended journaled format.
Exit Disk Utility and click Continue to begin the install
Select your new partition from the list and click Continue.
The installation will begin.
Click on Restart.
Boot off your USB Installer again and select HighSierraAMD again.
Click the Utilities Menu and select Terminal
At the Terminal enter Start to begin PostInstall, or if that fails enter:
Choose option 2
Enter the name you named your HighSierra volume
Choose option 11 to restart
Choose your USB Installer from the bios boot menu
Select your newly installed High Sierra Partition name
Select your country and click Continue
Choose your keyboard and click Continue
Click Don't Sign In and click Continue
Click Agree then Agree again
Enter your User Account Information
Click Customize Settings
Click Continue then click Don't Use
Select your time zone
Enable or Disable Siri
Setting up your mac
Now you can install enoch or clover bootloaders
Installing Clover for UEFI
Installing Clover Legacy Bios
Installing Clover to a partition with no EFI
Install Extra drivers for Clover with Clover Configurator
If you have an EFI partition, choose install into the ESP.
If you don't have and EFI partition, choose install into the chosen path.
Check the following options.
Once checked click on install to install Enoch.
Mount the EFI of the installer and open the Extra folder, inside will be an Extensions folder. Copy the files from there and place them into your EFI/Clover/Kext/Other folder, or if you're dual booting different macOS versions put it in 10.13.
Mount the EFI of the installer and copy the Extra folder over your existing Extra folder, whether it be in EFI or local hard drive. I've attached a good org.chameleon.boot.plist and an imac14,2 smbios.plist. If you can't boot with the 14,2 plist revert back to the 5,1 from the installer and try again. Also if you have an Nvidia card, you want to add NVIDIAWebDrv=Yes to Kernel Flags of the org.chameleon.boot.plist to load you web drivers every time.
I have attached zips of Clover Configurator (ccv.zip) and Kext Utility. I suggest when making your USB you copy them to the root of the drive to have when you get ready for post install.
