With the forth coming release of OpenCore Legacy Patcher v0.5.0, systems with legacy Metal GPUs will finally be able to achieve graphics acceleration in macOS Ventura!

  • Reminder: These patches are still in beta and in active development. Stay on Monterey if you're not comfortable with the trade offs listed

GPU Models

Supported GPU models include:

  • Intel:
    • Ivy Bridge (HD4000)
    • Haswell (HD4400/4600/5xxx)
    • Broadwell (HD6xxx)
    • Skylake (HD5xx)
  • Nvidia:
    • Kepler (GTX 6xx, GTX 7xx)
  • AMD:
    • GCN 1-3 (HD 7xxx/8xxx/9xxx, R7/R9, FirePro D300, D500, D700)
    • Polaris (RX 4xx/5xx) - (Hosts lacking AVX2.0)
    • Polaris (Radeon Pro 4xx/5xx) - (MacBookPro13,3/14,3)
    • Vega (RX 56/64/VII) - (Hosts lacking AVX2.0)

Note: MacBookPro14,3 tested to be exempt of all graphical issues listed below.

Sample Units
MacPro5,1 MacBookPro9,2
MacBookPro11,5 iMac11,3

Stability issues

Issues Severity Affected Models Potential Fix/Work-Around
"Sequoia" Metal dynamic wallpaper wallpaper won't render properly Non-Functional Nvidia Kepler GPUs
Some Metal apps crashing on Sonoma+ Non-Functional MacBookPro11,5 and iMac15,1 Downgrade to macOS Ventura
No hardware decoding on AMD Vega GPUs running Ventura+ Non-Functional AMD Vega (RX 56/64/VII) Downgrade to macOS Monterey
Photos app failing to edit portrait photos on Sonoma+ Non-Functional Intel Ivy-Haswell iGPUs and Nvidia Kepler GPUs Downgrade to macOS Ventura
Safari failing to reproduce DRM content on Sonoma+ Non-Functional All non-native GPUs (except MacBookPro14,3) Use a third-party browser
Paravirtualized Graphics is unavailable on Sonoma+ Non-Functional Intel Ivy-Haswell iGPUs and Nvidia Kepler GPUs Downgrade to Ventura
Broken Live Text Non-Functional Intel Ivy, Haswell iGPUs and Nvidia Kepler GPUs (portions require Metal 2) Use 3rd party OCR software
Black Screen on external GPUs if internal GPU is AMD Legacy GCN Semi-Functional AMD Legacy GCN + AMD Polaris eGPU Render on different display
Metal's Mesh Shader feature set not available Non-Functional All non-native GPUs (except MacBookPro14,3)
GeForceGLDriver Crashing Non-Functional Nvidia Kepler GPUs

Cosmetic issues

Issues Severity Affected Models Potential Fix/Work-Around
Native Metal 3 eGPUs may report as Metal 2 Cosmetic Haswell iGPUs Has no effect on driver feature set
Interface Build UI may become corrupted Semi-Functional Nvidia Kepler with Intel iGPU
Green Artifacts on QuickTime Timeline for .mov Cosmetic Intel Ivy and Haswell iGPUs
Artifacts on Cropped Screen recording Non-Functional Nvidia Kepler Record fullscreen, crop afterwards
  • Notes:
    • AMD GCN 1-3 issues are also applicable if your GPU is AMD Polaris and CPU lacks AVX2.0, e.g. MacPro3,1 - 5,1 and some select iMacs with upgradable GPUs. Additionally MacBookPro13,3 due to missing framebuffer.
    • Due to Apple's merge of on-disk binaries into the dyld_shared_cache, we're reliant on the DCSE project to extract binaries.
