I have a SilverStone SST-RVZ03B case for my ASUS ITX Z270, and it is an incredible pain to assemble and disassemble. It's a tiny box into which I have stuffed a single fan water cooler, a 3/4 sized power supply and 3 SSDs. The cooling fan is mounted on the outside.
I started this with a ITX Radeon RX570 which didn't work - see prior postings from earlier in the month. I retracted that and put BACK the NVidia GTX 950 and rebooted with no problems. So I then bought this RX580 as it was deemed 100% compatible all over this Forum. Unpacked the case, stuffed in the RX580 and booted to this nightmare. As I've said a million times this works fine on the Windows 10 boot.
Now I've re-enabled the IGPU in the BIOS and am running the Windows on it. But it doesn't change the failure to boot to any OSX.
Before I rip this pain apart again, I would like to know why I can't boot to the USB High Sierra install stick. What is happening there?
I think now this is an ACPI problem of some nature. Someone out there must have a suggestion - before I tear it apart.
Is there a BIOS setting that I'm missing - is this the common point? Any yes I have followed all advice I can find on BIOS defaults. And I have varied all I can find in the BIOS with regard to Graphics option - the latest being booting on the IGPU.
I'm now thinking of replacing the computer case to something bigger uglier but easier to jig.
My weekend homework will be to build a new USB Install stick from scratch, test it on my GA-Z97X hack and see if I can boot it on this Z270X hack.
I'm fishing for ONE more suggestion before I follow your advice, which believe me, I had already considered.
WTF?
Do you have the USB injection fix (high sierra version) installed on the USB stick drive itself? I had a problem similar to this where I couldn't get to the installer because my build couldn't recognize the USB Drive properly under MacOS because the USB ports weren't properly configured. I know they recommend the fix when installing MultiBeast but for some builds its also important to install it on the USB Stick itself too. This is the only thing I could think of that it might be.
