# Fixing System Clocks
|
||||
|
||||
What the [SSDT-AWAC](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-AWAC.dsl) will do is force enable the Legacy RTC device in macOS, the reason we want to do this is that macOS currently does not support AWAC as a system clock. In some rare cases, there is no Legacy RTC device to force enable so we'll need to create a fake RTC device for macOS to play with using [SSDT-RTC0](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-RTC0.dsl)
|
||||
|
||||
To determine whether you need [SSDT-AWAC](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-AWAC.dsl) or [SSDT-RTC0](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-RTC0.dsl), open your decompiled DSDT and search for `Device (AWAC)`. If you get a result then you have an `AWAC` system clock present, **if nothing shows then no need to continue and no need for this SSDT**. Otherwise, continue with the next search for `STAS ==`:
|
||||
|
||||

|
||||
|
||||
As you can see we found the `STAS ==` in our DSDT, this means we're able to force enable our Legacy RTC. In this case, [SSDT-AWAC](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-AWAC.dsl) will be used As-Is with no modifications required. Just need to compile.
|
||||
|
||||
For systems where no `STAS` shows up but you do have `AWAC`, you can use [SSDT-RTC0](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-RTC0.dsl) though you will need to check whether your DSDT uses `LPCB`, `LBC` or `LBC0`.
|
||||
|
||||
By default it uses `LPCB`, you can check by just searching for `Name (_ADR, 0x001F0000)`. This address is used for Low Pin Count devices(LPC) but the device name can vary between `LPCB`, `LBC` or `LBC0`. Just search each one in your config and which ever shows up is the one your system uses

# Fixing NVRAM
|
||||
|
||||
**This is required for all B360, B365, H310, H370, Z390 motherboards**
|
||||
|
||||
This SSDT brings back NVRAM support and uses the scope `PCI0.LPCB` to check what scope your system has, search your DSDT for `Name (_ADR, 0x001F0000)`. This address is used for Low Pin Count devices(LPC) but the device name can vary(quite rarely in reality, almost all consumer intel boards use `LPCB`)

# Fixing Power Management
|
||||
|
||||
**Intel CPUs only**
|
||||
|
||||
CPU naming is fairly easy to figure out as well, open your decompiled DSDT and search for `Processor`. This should give you a result like this:
|
||||
|
||||

|
||||
|
||||
As we can see, the first processor in our list is `PR00`. This is what we'll be applying the `plugin-type=1` property too. Now grab [SSDT-PLUG](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-PLUG.dsl) and replace the default `CPU0` with our `PR00`. Note that there are 2 mentions of `CPU0` in the SSDT.
|
||||
|
||||
There are also some edge cases with `Processor`, specifically on HEDT series like X79, X99 and X299. This edge case is that the ACPI path is much longer and not so obvious:
|
||||
|
||||

|
||||
|
||||
If we then search for instances of `CP00` we find that it's ACPI path is `SB.SCK0.CP00`:
|
||||
|
||||

|
||||
|
||||
So for this X299 board, we'd change `\_PR.CPU0` with `\_SB.SCK0.CP00` and `External (_PR_.CPU0, ProcessorObj)` with `External (_SB_.SCK0.CP00, ProcessorObj)`

# Renaming GPUs
|
||||
|
||||
So this is mainly needed for GPUs that are not natively supported OOB due to their names, most commonly:
|
||||
|
||||
* R9 390
|
||||
* R9 290/390
|
||||
* R9 280/380
|
||||
* R7 270/370
|
||||
* R9 260/360
|
||||
* R7 250X
|
||||
* R7 250
|
||||
* R7 240
