macOS AI Coding Tools Claude Code and OpenUsage Simplify Usage Tracking

Developers are turning spare Macs into dedicated hosts for Claude Code, Anthropic’s command‑line AI coding assistant. Users face macOS‑specific obstacles such as disabled SSH, Full Disk Access restrictions, power‑management sleep, and missing environment variables. A step‑by‑step guide recommends enabling Remote Login, granting appropriate permissions, and adjusting launch settings to keep Claude Code sessions alive on modern macOS releases (Sonoma, Sequoia, Tahoe).

A separate open‑source macOS menu‑bar app, OpenUsage, aggregates quota, credit and cost information for several AI coding services—including Claude, OpenAI Codex, Cursor, and GitHub Copilot—into a single panel. It displays weekly and session limits, reset timers, and estimated daily costs, helping users avoid exceeding allocated usage before large tasks. OpenUsage can be installed via a universal DMG or Homebrew and requires macOS 15 or later.
