I tried everything listed in that link and many other things found here and there but I could not get PM working on my Ivy bridge since Ventura. It was working great before that.

Is your power management working on the Ivy Bridge ?

Done on the Ivy Bridge OC v0.8.5 and OCLP 0.5.1 :

Done on my Z270/7700K OC v0.8.5

And without agdpmod ? (Keep amfi get out of way). Do not forget to reset nvram.

Try with boot arg : amfi_get_out_of_my_way=1

OCLP is designed for real Macs, yes. However it can be used with hacks for patching the system, not for installation. I use it on my Legacy system since 1st release of Monterey, never had a single problem. It is up to you to use it or not. Two things : - At the moment you will not get GVA...

The system is just as fast as Monterey. You need to remove -amd_no_dgpu_accel after patching with OCLP.

Then I do not know. Double check all your bios settings and if CSM is disabled (if your motherboard has got that option).

One last try :

You did not reset your nvram.

Try this EFI

Success on my Ivy Bridge :)

It is just the time to launch OCLP and apply the patch. I tested on my Ivy Bridge Hack and I could not boot into safe mode for some reason. I added to my config.plist NVRAM boot arg : -amd_no_dgpu_accel And here is a working Ivy bridge with Ventura :

Hi there, Is there any way to enter safe mode with Ventura ? I tried on two of my working hacks but all I get is a prohibited sign at boot (right after Opencore entry selection). I tried shift + enter or -x arg but nothing worked. I played with other quirks such as...

See change log here, V 0.5.0 : https://github.com/dortania/OpenCore-Legacy-Patcher/blob/main/CHANGELOG.md Graphics Acceleration for legacy Metal GPUs Intel: Ivy Bridge, Haswell, Broadwell and Skylake Nvidia: Kepler AMD: GCN 1 through 3 AMD: Polaris (on pre-AVX2.0 systems) Boot in safe mode...

If you boot in safe mode (hold shift + enter at opencore boot entry), what happens ? To me you lack the AVX2.0 instruction with your Ivy Bridge that is needed to drive the RX570 with Ventura. It loads the default macOS drivers. As I have an Ivy Bridge system too, I think we need to wait for...

Done :)

I am writing this message on my oldest hack from 2008 and running latest Monterey update : - P5QL Pro - LGA 775 hack with XEON X5460@4Ghz OC - 8GB RAM DDR2 (@832 Mhz, does not recognized as such by OpenCore) - MSI GTX 770 Lightning Edition 2GB - SSD SATA 512GB - 2x4TB HDD - Dual boot Windows 11 :)

Is wake from sleep working for you ? Mine was working since High Sierra until 12.1 but now it is broken.
