This EFI is compatible with all Ryzen and Athlon 2xxGE processors with macOS-compatible peripherals.
Support for 15h (FX series), 16h (A series) and Threadripper CPUs is not covered here.
Model | Compatible? |
---|---|
Integrated | No |
Nvidia | Partially 1 |
AMD | Yes 2 3 |
1 Support for Nvidia GPUs was dropped in Monterey Beta 7, the only way to get it back is using OpenCore Legacy Patcher. Kepler series under correct PAT Patch. Others require WebDrivers which work only in High Sierra or are not supported. More details on Dortania.
2 Some R7 and R9 GPUs require FakeID. More details here
3 Lexa series GPUs are not supported. Older than 7000 series are supported up to High Sierra (10.13), their support is not covered here.
For AMD Navi 10 and 20 Series GPUs (RX 5000 and RX 6000) you need to add agdpmod=pikera
to boot-args
to fix the black screen issue.
PAT Patch made by Shaneee is used by default. It improves GPU performance but it has a few caveats. Audio passed by HDMI or DisplayPort won't work or will be unstable. It also may not work with Nvidia GPUs.
If you want to control monitor's brightness or HDMI/DP audio volume you need to use MonitorControl for that.
All laptops with AMD CPUs are not supported due to integrated GPUs incompatbility.
Chipset | Details |
---|---|
B550, A520 | Requires SSDT-CPUR to boot. Details here. |
B550, A520, B450, X470, X570 | SetupVirtualMap has to be disabled. |
Other | Should be compatible out of the box. |
Follow these steps to properly install SSDT-CPUR.
- Download from here.
- Install it to your
OC/ACPI
directory. - Add it to your configuration file. Use ProperTree for simplicity.
On AM5 motherboards with on-board Thunderbolt/USB4, macOS Ventura may not enumerate devices on the PCI bus properly when on-board WiFi and on-board Thunderbolt are both enabled. Patch CaseySJ | IOPCIIsHotplugPort | Fix PCI bus enumeration on AM5 | 13.0+
bypasses the problem. This patch is disabled by default. If you have described issue you have to enable this patch.
To disable SetupVirtualMap
simply go to Booter -> Quirks -> SetupVirtualMap
in your configuration file and disable it. (Should be false
).
If you have the Above 4G Decoding
option in your BIOS settings, enable it and remove the npci=0x2000
parameter from the boot-args
(NVRAM section).
If you have the Resizable BAR
option in your BIOS settings and your GPU supports it, you can enable it for better GPU performance. Then, set Booter -> Quirks -> ResizeAppleGpuBars
to 0
.
If you experience issues related to Secure Boot in the macOS installer, set Misc -> Security -> SecureBootModel
to Disabled
. After installation, you can set it to the value corresponding to the used SMBIOS. Look here for more information.
Follow these steps if your audio chipset is different than the one specified in the Specification.
- Go here to find your audio chipset codec. (Under Codec)
- If you can't find your codec on the list, then you probably have to use VoodooHDA. This repository does not cover or support the use of VoodooHDA.
- Under Revisions and layouts you'll see bunch of numbers and layout ids.
- Find your
boot-args
settings and look foralcid=11
. - Try every layout id (except 0x values) one by one until it works.
- Example:
alcid=10
iflayout 10
- Example:
Caveats:
- External (USB) audio cards should work out of the box.
- If you have CPU with integrated GPU (even if you don't use it) your audio may be broken or unstable. You can try using SpeedKeeper but it's not guaranteed to fix your problem. The best solution is using external (USB) audio card.
If you experience any issues with your network connection, then your best bet would be to install a different kext, preferably from here.
If you use High Sierra and Realtek 8111 Ethernet Card then you should use older version of kext.
If you have issues with network card on Monterey or newer try adding e1000=0
to boots-args
.
SmallTree kext does not work on Monterey for now. You can try AppleIGB kext, it works on some systems. If it does not work you have to stay on Big Sur and wait for SmallTree's update.
Only Apple Airport and Fenvi cards work out of the box. Here you can list of all supported cards and needed kexts for them.
Rembember that AirDrop, Handoff, etc. works only on cards with Broadcom chip.
Option | Status |
---|---|
SATA Mode | AHCI |
Above 4G Decoding | Enabled 1 |
EHCI/XHCI Hand-off | Enabled |
SVM | Enabled |
CSM | Disabled |
Secure Boot | Disabled |
Serial Port | Disabled |
Parallel Port | Disabled |
1 If you have this option in BIOS you must also remove npci=0x2000
from boot-args
in your configuration file.
Some of these options may not exist in your firmware, just try to match it as closely as possible.
Before booting macOS remember to update BIOS to the latest version.
-
Follow this guide to create your bootable USB.
-
Clone this repository and copy "BOOT" & "OC" directories to your "EFI" directory on your bootable USB. The structure should look somewhat like this:
EFI -> BOOT, OC
.
- Modify Core Count patches to match your CPU's cores amount.
-
Find four
algrey - Force cpuid_cores_per_package
patches underKernel -> Patch
in your config. -
Modify these patches for your CPU physical cores. Change first pair of
00
inReplace
of these patches toHex value
from below table.- e. g. for Ryzen 7 1700 with 8 Cores three modified patches should look like:
- B8 00 0000 0000 -> B8 08 0000 0000
- BA 00 0000 0000 -> BA 08 0000 0000
- BA 00 0000 0090 -> BA 08 0000 0090
- BA 00 0000 00 -> BA 08 0000 00
- e. g. for Ryzen 7 1700 with 8 Cores three modified patches should look like:
Physical CPU cores | Hex value |
---|---|
4 Cores | 04 |
6 Cores | 06 |
8 Cores | 08 |
12 Cores | 0C |
16 Cores | 10 |
24 Cores | 18 |
32 Cores | 20 |
- Use this tool to generate your unique SMBIOS info.
-
SMBIOS has to be unique, you cannot use one present in this repository.
-
Run the tool and select
Generate SMBIOS
. -
Select the appropriate model for your hardware using the table below.
-
Go to Apple Coverage and paste generated Serial. You need "Invalid Serial" or "Purchase Date not Validated" message. If you get something another you have to generate SMBIOS data and check it again.
-
Open config.plist and search for
PlatformInfo -> Generic
and replace these values:- SystemProductName - Model
- MLB - Board Serial
- SystemSerialNumber - Serial
- SystemUUID - SmUUID
-
ROM entry should be set to your network card's MAC address, without separators (e. g.
:
,-
).
