Ventoure with Opencore on Imac 12.1

[agala68]

Hi,
I have an Imac 12.1, mid 2011 21.5 inches upgraded with Xen CPU and NVIDIA Quadro K2100M GPU, perfectly owrking in Monterey using Opencore,it is not in the list but I wonder if since my GPU support Metal 1v1 until 1v4, it should be possible to install Ventura with Opencore.
Thank in advance

I don't think so. See https://dortania.github.io/OpenCore-Legacy-Patcher/VENTURA-DROP.html#current-status

Currently Unsupported/Broken Hardware in Ventura​

#AMD Polaris, Vega and Navi support on pre-2019 Mac Pros and pre-2012 iMacs​

For users with 2008 to 2013 Mac Pros (MacPro3,1-6,1) and 2009 to 2011 iMacs (iMac9,1-12,2), keep in mind macOS Ventura now requires AVX2.0 support in the CPU (opens new window)for native graphics acceleration. Thus while your GPU may be natively supported, you cannot run Ventura officially with these GPUs.

I know it says AMD GPUs but I interpreted the paragraph as valid for all machines lacking AVX2.0 support.

but AVX 2.0 is a CPU or GPU feature?

if I check mine, it says:

Imac-di-Andrea:~ agalanti$ sysctl -a | grep machdep.cpu.features
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0

not a good new, but I also read in the web:

I've bolded the presence of the AXV1.0 CPU feature in the report from my Mac: iMac 27" Late 2012 3.4GHz Core i7.

In the same opencore page:

macOS Ventura | OpenCore Legacy Patcher

says:

• CPUs supporting AVX2.0 are Haswell or newer, which no pre-2019 Mac Pros can be upgraded with.

Just looking for experience using open core? I have a 2011 iMac looking to upgrade with OpenCore
