Cleanup

So you've made all your SSDTs but now there's one thing left: Adding them to Opencore

The 2 main locations:

EFI/OC/ACPI (Only .aml files, reminder to compile your SSDTs)
config.plist -> ACPI -> Add

You can save yourself some work with the config.plist by running Cmd/Ctrl+R in ProperTree. Reminder do not add your DSDT.aml to your EFI

For those who do not yet have a config.plist, you'll want to next head back to your respective OpenCore guides and create the config.plist:

Users of FixHPET will also need to merge oc_patches.plist into their config.plist

Steps to do this:

Open both files,
Delete the ACPI -> Patch section from config.plist
Copy the ACPI -> Patch section from patches.plist
Paste into where old patches were in config.plist
