Why Macs quietly win at local AI: unified memory beats RTX 5090 and accessibility APIs power better computer use
dotey · x · 2026-09-15
- Unified memory: M-series Macs offer 48GB+ of unified memory for running LLMs locally, versus 32GB VRAM on a $5,000 RTX 5090.
- Accessibility APIs: macOS's accessibility tree lets agents click controls by name instead of screenshot-based coordinate guessing, making computer use far smoother than on Windows.
The author argues pure vision-based coordinate control is a flawed approach.
