OpenCore-Post-Install VS ProperTree

Rename PTS to ZPTS: https://github.com/dortania/OpenCore-Post-Install/blob/master/extra-files/FixShutdown-Patch.plist

I think that particular kext requires SecureBoot to be setup.

Source: https://github.com/dortania/OpenCore-Post-Install/blob/master/extra-files/SSDT-GPRW.aml https://github.com/dortania/OpenCore-Post-Install/blob/master/extra-files/GPRW-Patch.plist

I know many people have posted about this already and I know what the issue is related to. I have been trying for days to make the FixShutdown-USB-SSDT.dsl method from Dortania work but the instructions are very unclear.. This is actually my first time asking for help because I'm really stuck and don't know how to proceed.

Then I assumed that I need an editor that can open .aml/.dsl files and use it to find some text in the DSDT.aml, which then I have to paste into the FixShutdown-USB-SSDT.dsl. For this purpose I used MaciASL (which is also not mentioned in the instructions).

- Grabbed SSDT-USBX from here

Also download SSDT_USBX.aml from here;

Open the config in ProperTree (https://github.com/corpnewt/ProperTree) and do a clean snapshot (CMD-SHIFT-R). This will put all of the kexts in the right order.

Open your config.plist using ProperTree.

NO. Prebuilts are a bad way to start. They are not updated and aren't configured to your specific needs. Make your own EFI and also don't use OCAT, use ProperTree which can do OC specific things like OC (clean) snapshots.

ProperTree

Try looking into a program called ProperTree. Has a GUI implementation to easily edit https://github.com/corpnewt/ProperTree

Used the Ryzen and Threadripper(17h and 19h) OpenCore Install Guide for with OpenCore v0.8.7 in combination with OpenCore Auxillary Tools, Sanity Checker & ProperTree.

Use propertree. It is hands down, the best IMO. https://github.com/corpnewt/ProperTree

You need to mount your EFI partition (find a tool online or use command line). In it you should find "EFI/OC/config.plist". Open the file with Propertree or another plist editor and make the changes.

If anything, keep .contentFlavour files removed and try updating your config.plist using ProperTree or some other plist editor which just makes it easier to read. Sorry I couldn't be of much help but its the best I've got right now haha.
