Perplexity Computer can run completely local on Mac, with a big caveat

AI-summarised brief · reviewed before publication

Perplexity Computer now runs entirely on Apple Silicon Macs, supporting Qwen 3.6 and PPLX Pro models locally. The fully local version can interact with native apps—Notes, Messages, Mail, Numbers—performing tasks such as drafting emails, updating spreadsheets, and preparing presentations. Users may also grant cloud access for additional models and real‑time data. Perplexity recommends 36 GB of unified memory, exceeding the capacity of many recent Macs, which limits deployment options. Apple plans tighter Full Disk Access controls to protect user privacy.

💡 Why It Matters

  • · The high memory requirement forces users to upgrade hardware or accept cloud fallback, revealing a gap between local AI ambition and current Mac capabilities.
  • · This constraint could shape how businesses adopt on‑premise AI agents.
