Optimize Mac Skill

Optimize My MacBook for Speed

A Claude Code skill that audits and optimizes your Mac's performance. Born from a real debugging session where a single Chrome tab was eating 15 GB of RAM.

What it does

1. System Snapshot — audits memory, swap, processes, DNS, and startup items
2. Kills Runaway Processes — safely terminates Chrome tabs leaking memory (>6 GB)
3. DNS Optimization — switches from slow ISP DNS to Cloudflare 1.1.1.1
4. Animation Tweaks — disables 7 macOS animations for instant UI response
5. Memory Watchdog — installs a persistent background monitor that auto-kills leaked Chrome tabs and warns about memory hogs
6. Login Item Audit — identifies unnecessary startup apps consuming resources
7. Full Report — presents before/after metrics with reversal instructions

Safety

• Never kills system processes or non-Chrome apps without asking
• All changes are reversible with documented undo commands
• Never uses memory_pressure (a stress-testing tool that makes things worse)
• Lets macOS manage its own VM subsystem — only intervenes for clear runaways

Install

git clone https://github.com/Casper0301/optimize-mac-skill.git ~/.claude/skills/optimize-mac

Then restart Claude Code and say "optimize my Mac" or run `/optimize-mac`.

Requirements

• macOS (any version with Apple Silicon or Intel)
• Claude Code with Max subscription

What you get

• Full system performance audit
• Automatic Chrome memory leak cleanup
• Persistent watchdog (runs every 5 minutes via launchd)
• DNS optimization (Cloudflare 1.1.1.1)
• 7 animation performance tweaks
• Startup item audit
• Before/after report with undo instructions
