If you still need .aml tables, you can simply rename the files; converting them is not necessary. We can simply select a folder containing our tables in SSDT using option ```D. Select ACPI table or folder containing tables```. +{: .note } +Below you will find a list of all SSDTTime options. However, that does NOT mean you should select every one!

FixHPET +- *1.* **FixHPET** Using the FixHPET option will create ```SSDT-HPET```. ```SSDT-HPET``` re-defines the HPET's _CRS method to claim IRQs (Individual Interupt Requests) that macOS expects the device to be assigned to it. It requires several ACPI patches to remove conflicting IRQs from other devices, as well as renaming the HPET's _CRS method to XCRS in order to re-define it. Creating ```SSDT-HPET``` will also create several ACPI patches that we can find in the also generated ```patches_OC.plist```. ```SSDT-HPET``` will be useless if you dont merge them into your ```config.plist```. -2. FakeEC -Using the FakeEC option will generate SSDT-EC. This SSDT disables our existing embedded controller (EC) as it is not compatible with macOS. It automatically searches for the ACPI path of our chip and disables it if booting Apple's kernel. +SSDTTime will show us conflicting IRQs: + +

This SSDT disables our existing embedded controller (EC) as it is not compatible with macOS. The EC is usually responsible for system paths, sensors, etc - since using the EC is not an option for us, we will provide needed data directly to the kernel using kexts.

FakeEC then creates a fake EC that is compatible with macOS. + +- *3.* **Laptop EC** +Laptop EC creates a fake macOS-compatible companion EC named "EC" - it leaves the original untouched as the built-in EC is what manages battery statistics, brightness notifications, hotkeys, etc. Instead, it generates a patch to rename it if it's already named "EC". + +- *4.* **USBX** +Starting with Skylake, systems started to change the way they handle USB devices. Consequently, USBX defines USB power properties - it defines a top-level USBX device. When a high-powered USB device is plugged in, the operating system gets informed of the appropriate power level to provide. SSDT-USBX is only needed on SMBIOS (System Management BIOS) based on Skylake and newer. + +SSDTTime is going to show us our USBX device properties: + +
