Ventura issues to understand
AVX2 graphics constraints
Ventura requires AVX2 for native graphics acceleration, affecting 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
Older Atheros and Broadcom wireless issues were documented as resolved in OCLP 0.6.0 and newer, but hardware still matters.
Non-Metal
Non-Metal graphics acceleration was a major challenge in earlier Ventura notes and is model dependent.
