How to Fix OC Boot Menu error & SSDTTime error?
This mini-guide provides a structural approach to troubleshoot and fix the issue.
Prerequisites
- Confirm your hardware specifications (CPU, GPU, Motherboard).
- Ensure you have a bootable recovery USB and backup your EFI.
Fix Steps
- Verify your network controller model (Intel, Broadcom, Realtek).
- Ensure the correct kext (e.g., AirportItlwm or BrcmPatchRAM) is loaded in your config.

Can someone help me with my problem? When OC Boot Menu appears after booting off USB, there are FOUR options... [1] Windows [2] KING 16GB (external) (dmg) [3] OpenShell.efi [4] Reset NVRAM The OC Guide says to select "[2] macOS Base System (External)". My option [2] says the USB name and with (dmg) which im thinking maybe it broke or something?. Even though it says that, I still select [2]. It goes black for a few seconds and then text appears fast and reboots back into Windows 10. Clearly something doesn't work. While I was creating the USB, when it came to the SSDTs part, i clicked on "Desktop - AMD (17h-19h): SSDT-EC-USBX". I tried using SSDTTIME option. When opened, I did "Dump DSDT" and .aml file showed up in "Results" folder. The OC Guide also says to run "FakeEC", which I TRY to do, but I get a message saying... Locating PNP0C09 (EC) devices... - None found - only needs a Fake EC device Locating LPC(B)/SBRG... -Could not locate LPC(B)! Aborting! I'm not sure why it does this. Since I kept getting this "error", I decided to instead go with the Prebuilt option and downloaded "SSDT-EC-USBX-DESKTOP". Could this be the cause of my problems? Originally, I tried to make USB with BigSur, and it didn't work (same problem). I'm thinking that maybe BigSur doesn't work for my PC, so I go with Catalina. Again, same problem occurs as I mentioned above. Can anyone help?
