Key Ventura issues
AVX2 graphics constraints
Ventura requires AVX2 for native graphics acceleration, which affects pre-Haswell Macs with certain upgraded GPUs.
USB 1.1 removal
Penryn systems and pre-2013 Mac Pros can lose support for keyboard, trackpad, IR, and Bluetooth devices that rely on USB 1.1.
Wireless notes
OCLP 0.6.0 and newer resolve many older Atheros and Broadcom wireless issues, but your exact hardware still matters.
Non-Metal
Non-Metal graphics acceleration remains a model-dependent challenge on Ventura.
