Top Mac Performance and Storage Boosts | Generated by AI
Here are the highest-impact things you can do right now, ranked by ROI:
Biggest Wins
| Action | Saves | How |
|---|---|---|
| Clear JetBrains cache | ~7 GB | rm -rf ~/Library/Caches/JetBrains/ |
| Homebrew cleanup | ~3 GB | brew cleanup --prune=all |
| pip cache purge | ~2.4 GB | pip cache purge |
| Clear WeChat cache | ~5-10 GB | WeChat Settings > Storage > Clear |
| Close Vivaldi/Safari tabs | ~10 GB RAM | Close what you don’t need |
| Quit WeChat when not using | ~5-19 GB RAM | Just quit the app |
| Quit idle VSCode projects | ~15 GB RAM | Close unused windows |
| Switch input method (WeType→Apple) | ~3.5 GB RAM | System Settings > Keyboard |
Additional considerations
- Spotlight indexing — the 250% CPU spike is normal after boot. Give it 15 min. You can exclude
node_modules/,~/Projects/,~/Library/Caches/in Spotlight Privacy settings to keep it fast long-term. - 48GB free — I’d aim for >100GB. Safest cleanup: JetBrains cache + Homebrew + pip alone frees ~12GB.
Want me to run any of the cleanups? I can also recommend what to move to your remote RTX 4070 machine (compilation, ML, heavy dev) so this laptop stays lean as a thin client.
