How to Find ACPI path of your PCIe Devices
This guide covers finding ACPI path of your PCI Devices for various hardware fixes. ACPI path is required especially for incorporating SSDT fixes which could be used to inject device properties or spoofing the device itself. By following this guide, you'll be able to find the ACPI path of your PCIe device.Overview
To fix certain hardware, you may need the ACPI path of your PCIe Device. To find the ACPI path of your PCI Devices follow the steps below:STEP 1: Download Hackintool from the Download section.
STEP 2: Open Hackintool.
STEP 3: Go to PCIe Tab
STEP 4: Under Device Path, you can find all the PCIe Devices connected to your system.
STEP 5: Right click on the ACPI path you want to copy in the IOReg Name column, just right next to the subclass column and select Copy IOReg Path.
STEP 6: For example, in our case, the ACPI path for the WiFi device is IOService:/AppleACPIPlatformExpert/PC02@0/AppleACPIPCI/BR2C@4/IOPP/ARPT@0. But the actual ACPI path starts after AppleACPIPlatformExpert and you'll have to disregard all the numbers with @ prefix and as well as AppleACPIPCI, IOPP. So, in our case, the actual ACPI path for WiFi device would be PC02.BR2C.ARPT.
