<p>What we&apos;ll be doing is hiding our actual EC and creating a fake Embedded Comtroller for macOS to play with.</p>
<p>To find out what EC you have, open your decompiled DSDT and search for <code>PNP0C09</code>. This should give you a result like this:</p>

<p>As you can see our <code>PNP0C09</code> is found within the <code>Device (EC0)</code> meaning this is the device we want to hide from macOS(others may find <code>H_EC</code>, <code>ECDV</code>, etc, everyone&apos;s systems will be different). Now grab our SSDT-EC and uncomment the EC0 function(remove the <code>/*</code> and <code>*/</code> around it):</p>

<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 vs 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.
