Mac mini has emerged as the de facto hardware substrate for persistent AI agents, driven by three converging agent runtimes: Perplexity Personal Computer, OpenClaw, and Hermes Agent. Apple's Q2 2026 earnings call confirmed the trend, with Tim Cook citing supply shortages and CFO Kevan Parekh naming Perplexity directly. The Mac mini's appeal stems from its low idle power (4W), unified memory architecture supporting large quantized models via Ollama, deep macOS integration (iMessage, Shortcuts, Keychain), and a cost advantage over cloud VMs. The three runtimes differ significantly: Perplexity is a hybrid local-cloud harness with 400+ connectors, OpenClaw is API-key-flexible with deep macOS hooks and a large community, and Hermes is a local-first agent with a closed learning loop and cross-session memory. Despite their differences, all three communities recommend Mac mini as the cleanest always-on deployment target. Apple's announcement of a new Mac mini factory in Houston signals this demand is being treated as durable.
