<p>But looking back at the screenshot above we notice something, our ACPI path is different: <code>PC00.LPC0</code> vs <code>PCI0.LPCB</code>. This is very important especially when you&apos;re dealing with Intel consumer vs Intel HEDT and AMD, <code>PC00.LPC0</code> is common on Intel HEDT while <code>PCI0.SBRG</code> is common on AMD. And they even come with name variation such as <code>EC0</code>, <code>H_EC</code>, <code>PGEC</code> and <code>ECDV</code>, so there can&apos;t be a one size fits all SSDT, <strong>always verify your path and device</strong>. </p>
<p>And make sure to scroll to the bottom as the new Fake EC function also need the correct path to replace the old EC. <strong>Do not rename the EC device itself</strong>, this is our fake EC we&apos;re using for macOS to play with. Just change the path!</p>

<p>This means your SSDT can be <em>almost</em> complied, the main thing to watch for is whether your DSDT uses <code>PCI0.LPCB</code> or not. The reason being is that we have a FakeEC at the bottom of our SSDT that needs to connect properly into our DSDT. Gernally AMD uses <code>SBRG</code> while Intel HEDT use <code>LPC0</code>, <strong>verify which show up in your DSDT</strong>.</p>
<p>You can check by just searching for <code>Name (_ADR, 0x001F0000)</code>(this only works for Intel, AMD users should assume <code>SBRG</code>). This address is used for Low Pin Count devices(LPC) but the device name can vary between <code>LPCB</code>, <code>LBC</code> or <code>LBC0</code>. Just search each one in your config and which ever shows up is the one your system uses</p>
