🚀 “My Mac Was Slower Than Ever — Until I Ran This One Terminal Command (M1/M2 Users Must Try This!)”

💻 The Problem

If you’ve owned a Mac for more than a few months, you’ve probably noticed it — apps take longer to open, Safari hangs for a second too long, and that fan that never used to spin suddenly won’t stop.

Even the mighty Apple Silicon M1 or M2 chips aren’t immune to cache bloat — hidden folders full of temporary files, logs, and system junk that silently eat away your storage and speed.

I used to dig through Finder manually, deleting random cache folders. It worked… kind of. Then I found a faster, cleaner, geek-approved way — one simple Terminal script.

⚙️ The Fix: A One-Line Cache Cleanup Script

Here’s the exact script I used to clear my Mac’s system and app caches safely.

Works perfectly on macOS Monterey, Ventura, Sonoma, and newer (including M1 & M2 chips).

🧠 Step 1: Open Terminal

You’ll find it under:

Applications → Utilities → Terminal

Or hit Command + Space, type “Terminal”, and press Enter.

🧩 Step 2: Create the Script

Type this command:

nano ~/Desktop/clear_cache.sh

Then paste the script below:

#!/bin/zsh
echo "🧹 Starting full Mac cache cleanup..."

sudo -v

echo "→ Clearing user cache..."
rm -rf ~/Library/Caches/*

echo "→ Clearing system cache..."
sudo rm -rf /Library/Caches/*

echo "→ Clearing temporary files..."
sudo rm -rf /private/var/folders/*

echo "→ Flushing DNS cache..."
sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

echo "→ Clearing Safari cache (if exists)..."
rm -rf ~/Library/Safari/*
rm -rf ~/Library/Caches/com.apple.Safari/*
rm -rf ~/Library/Caches/Metadata/Safari/*

echo "→ Clearing log files..."
sudo rm -rf /private/var/log/*
sudo rm -rf ~/Library/Logs/*

echo "✅ Cache cleanup complete! Restart recommended."

Save it by pressing:

Control + O → Enter → Control + X

⚡ Step 3: Make It Executable & Run

Run these two commands:

chmod +x ~/Desktop/clear_cache.sh
sudo ~/Desktop/clear_cache.sh

Enter your Mac password (it won’t show as you type).

Now sit back — your Mac will do a deep clean of all caches, temp files, and logs.

When it’s done, restart your Mac.

💥 The Result

I instantly freed over 12 GB on my M1 MacBook Air. Apps launched faster, and Safari finally stopped beach-balling. It felt like a fresh install — without reinstalling macOS.

Here’s what it cleaned:

✅ User caches

✅ System caches

✅ DNS cache

✅ App temp files

✅ Safari junk

✅ Log files

💡 Bonus Tip: Make It Permanent

Want to reuse it anytime?

Run:

sudo mv ~/Desktop/clear_cache.sh /usr/local/bin/clearcache
sudo chmod +x /usr/local/bin/clearcache

Now you can just type:

sudo clearcache

from any Terminal window, whenever your Mac feels sluggish. 💨

🧠 Why It Works

macOS caches improve performance — until they don’t. Over time, they pile up from app updates, web browsing, and system logs. Apple doesn’t provide a single “Clear All” button, but this script does exactly that — safely.

It doesn’t touch your personal files or system libraries — just removes old, rebuildable caches.

✨ Final Thoughts

If your Mac feels slower, don’t rush to upgrade or reset.

Try this first — it’s quick, reversible, and shockingly effective.
