Section D3. Once you execute the command to make the installer USB, the name of the stick will always be the same...

Once you execute:

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction

The USB name will always be:

'/Volumes/Install macOS High Sierra'
 
Thank You,

I'll recompile the AptioMemoryFix. If I understand correctly, we're not supposed to need the BIOS edits on the X299 Designaire EX motherboard. In the meantime, I am going through the process again using a LEEP 32GB USB 3 stick instead of the SSD in a USB case. I will document each action.

Yes you do...
You must disable CSM at least.
 
So I updated 10.13.4 from app store. Only one monitor working after updating. But several reboots made both monitors are working well..but, there is weird issue with itunes 12.7.4 the latest version. When I click it to open and all system currupted. finder not working and folders and apps not opened. Anyone has the issue with itunes?? So I download itunes 12.7.3 which is working fine in 10.13.4 no issue at all. But why 12.7.4 itunes has problem? anyone can test?

Are you using an AMD Vega card?

If so, install the Lilu.kext and the VegaGraphicsFixup.kext I provided earlier...

I do not need both lilu or whatevergreen and vegagraphicsfixup kext. My 5k +4K monitors are fine working without those files. sleep and wake working well. But itunes the latest version not working in 10.13.4. I am thinking I should clean install soon.
 
Observation on 10.13.4:

- The issue with AMD Vega card running at high fan speeds has not been resolved
- The AMD Vega high fan speeds stop, when you open this video: https://drive.google.com/file/d/1XDUvAjYGnpuhtlGWXUyAQ4bJr9MC9Q9A/view
- The AMD Vega stops crazy blinking on it's LEDs, when you cut the Internet connection

Wonder to myself: Has Apple implemented bitcoin mining in the background for themselves? It looks like they want to keep the system snappy (i.e. when you open the video), but will use graphic card resources in idle.

What is going on here?
