A Reddit post argues the 2019 Mac Pro — with up to 1.5TB of system RAM and room for four passively cooled GPUs carrying 128GB of VRAM — would be the ideal local LLM machine if sold today with modern components. Apple discontinued it in favor of machines capped at 192GB unified memory. The author concedes it would be expensive, but blames market conditions, not the design.
