## What this SSDT does
|
|
|
|
The purpose of SSDT-EC/USBX is a couple things:
|
|
|
|
* On desktops, the EC(or better known as the embedded controller) isn't compatible with AppleACPIEC driver, to get around this we disable this device when running macOS
|
|
* AppleBusPowerController will look for a device named `EC`, so we will want to create a fake device for this kext to load onto
|
|
* AppleBusPowerController also requires a USBX device to supply USB power properties for Skylake and newer, so we will bundle this device in with the EC fix
|
|
* On laptops, the EC is used for hotkeys and battery so disabling this isn't all too ideal. Problem is our EC's name isn't compatible, so we will create a simple "fake" EC device that will satisfy Apple
|
|
|
|
So TL;DR:
|
|
|
|
* EC is embedded controller
|
|
* Desktops will want real EC off, and a fake EC created
|
|
* Laptops will just want an additional fake EC present
|
|
* Skylake and newer devices will want USBX as well
|
|
|
|
## Methods to make this SSDT
|
|
|
|
For the EC fix, there are 3 methods you can choose from:
|
|
|
|
* [Prebuilt](/Universal/ec-methods/prebuilt.md)
|
|
* [SSDTTime](/Universal/ec-methods/ssdttime.md)
|
|
* [Manual](/Universal/ec-methods/manual.md)
