Mac Maintenance

The recurring "keep it current" pass, run safely: show before changing, respect self-updating apps and pinned majors, never surprise-restart the machine. Designed to be re-run weekly/monthly — every step is idempotent.

When NOT to use

• First-time setup of anything → the respective setup skill
• Broken brew (doctor errors) → homebrew-setup
• Project dependency upgrades (package.json, lockfiles) → project work
• macOS major-version migration → manual, deliberate; only point at System Settings
