[Solved] Direct Upgrade to macOS High Sierra Not Working for Me

[karacho]

Thanks - now the installation worked! I guess I just need to fix the sound.
But most important: How can i drop mats continiuseley?

Do I have to embed this code:

<key>APCI</key>
<key>DropTables</key>
<array>
<dict>
<key>Signature</key>
<string>MATS</string>
</dict>
<dict>
<key>Signature</key>
<string>DMAR</string>
</dict>
</array>

...into my config.plist? If yes, where exactly?
Thanks!

Use Clover Configurator to edit your config.plist. It's the easiest way with the dropdown item.

Hi I am having the same issue, I have checked and Vtd is disabled, and ACPI is activated. I get the Apple logo after restart, I have followed the guide as Jackblack87 did, however I cannot get past the apple logo. I have went into clover config and added drop MATS, however the last section of the table I don't know which option to choose.

Read post #164 Credit to @vulgo

"ACPI: VT-d can be disabled in firmware settings (under CPU features), otherwise we can drop DMAR table. MATS is known by some to prevent 10.13 boot so drop that as well."

Code (Text):

<key>APCI</key>
<key>DropTables</key>
<array>
<dict>
<key>Signature</key>
<string>MATS</string>
</dict>
<dict>
<key>Signature</key>
<string>DMAR</string>
</dict>
</array>

"Recent betas seem to raise problems with SIP partially disabled, resulting in errors later on in boot. This log is from a boot into 10.12, but setting the CSR bits 0x3FF for booting High Sierra."

Code (Text):

<key>RtVariables</key>
<dict>
<key>BooterConfig</key>
<string>0x28</string>
<key>CsrActiveConfig</key>
<string>0x3FF</string>
</dict>

Isn't there any other workaround to get rid of this problem? I repeat my Problem:
I followed the APFS guide
