I don't know if anyone still looks at this post but currently I am in the process of installing 10.13 onto my own Z600.
I've been having a few issues completing and getting the system fully up and running. Sorry but these will be listed and if anyone can help I would be so greatful.
1, macOS (The drive I would like to install OS onto) disappears on occasions during start ups and at the points before changing the APFS to false task.
I had to restart, tweak settings and on some occasions unplug drive and place in another system to repair drive just so the Z600 could see it during setups.
2, For some reason I'm unable to do the unibeast option as when using application on my MacBook it couldn't see a usable drive.
So the only option I could do was the Cover option.
3, The Clover Version I use is a newer version (Clover_v2.4k_r4920) and doesn't quite look like the one shown in the example. Is Clover meant to download Kext files (Basic Drivers) that it believes it requires or should I de-select the option?
Update: I did both options and the same results.
4, I got to a point where it gets to main screen, looks awesome, little delays (Perhaps due to the drivers missing). Here I can shutdown and restart but with the Bootloader Drive still part of the system but I'm choosing macOS as my startup.
It's after I use Clover to create the EFI-folder, copy the Config file, add all the Kext files to (10.13 and Other) then do the reboot the problem appears.
I'm following the Tutorial step by step...
Unplug the Bootloader Drive (Not wiped as I may use it again) move the SSD (Yes APFS footnote 1 was followed too) into the first drive bay in the case and started the computer back up.
The computer starts up then comes to this weird Bios Screen (See Picture) can't continue as it just goes into a loop forever and would have to shutdown computer.

I have done reinstalls and on one time I went through the Bootloader to see if the drive was having an issue and it had disappeared from the Clover Menu with only a recover drive which was no help at all.
5, I know another issue, I tried getting rid of the Apple.HPET file incase that was an issue but this was before adding all the kext files to see if I could have USB working while not fully complete.
Results: Nothing!
These PS2 adapters are great investments.
I know this is a lot to take in and I bet the original poster doesn't have his system anymore but I just want to see this Z600 purr and work with me.
If anyone can help that would be fantastic!
