<p>So this is mainly needed for GPUs that are not supported in macOS, mainly this will be Nvidia users who wish to pair an AMD GPU for macOS use. While WhateverGreen does support the boot-arg <code>-wegnoegpu</code>, this only works when running on iGPU so for the rest of us we&apos;ll need to make an SSDT.</p>

<p>Hey what about USBX? Do I need to do anything?</p>
</blockquote>
<p>USBX is universal across all systems, it just creates a USBX device that forces USB power properties. This is crucial for fixing Mics, DACs, Webcams, Bluetooth Dongles and other high power draw devices. This is not mandatory to boot but should be added in post-install if not before. Note that USBX is only used on skylake+ systems, Broadwell and older can ignore and that USBX requires a patched EC to function correctly</p>
