<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>

Now grab our SSDT-EC and uncomment the EC0 function(remove the <code>/*</code> and <code>*/</code> around it):</p>
