Legacy Metal Graphics Support and macOS Ventura - Sequoia

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.

Sequoia issues

Issues	Severity	Affected Models	Potential Fix/Work-Around
"Sequoia" Metal dynamic wallpaper wallpaper won't render properly	Non-Functional	Nvidia Kepler GPUs
Software Update stalling with a spinning circle	Non-Functional	NVIDIA Kepler GPUs	Use command line to update

Sonoma+ issues

Issues	Severity	Affected Models	Potential Fix/Work-Around
Some Metal apps crashing or misbehaving	Non-Functional	MacBookPro11,5 and iMac15,1	Downgrade to macOS Ventura
Photos app failing to edit portrait photos	Non-Functional	Intel Ivy-Haswell iGPUs and Nvidia Kepler GPUs	Downgrade to macOS Ventura
Safari failing to reproduce DRM content	Non-Functional	All non-native GPUs (except MacBookPro14,3)	Use a third-party browser
Paravirtualized Graphics is unavailable	Non-Functional	Intel Ivy-Haswell iGPUs and Nvidia Kepler GPUs	Downgrade to Ventura

Ventura+ issues

Issues	Severity	Affected Models	Potential Fix/Work-Around
No hardware decoding on AMD Vega GPUs	Non-Functional	AMD Vega (RX 56/64/VII)	Downgrade to macOS Monterey
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.
