🔍 Why Your MacBook Air M3 Might Be Running Slow

Even powerful machines can face slowdowns. Here are a few common reasons:

• Low storage space
• High background app activity
• Corrupted system caches or files
• Poor thermal management triggering kernel_task overuse
• Outdated macOS or app versions

Identifying the root cause is key before applying fixes. Let’s go over the solutions step by step.

✅ 1. Free Up Storage Space Immediately

One of the first things you should do is check your available disk space. If your SSD is almost full, your MacBook will slow down significantly. Therefore, try to keep at least 15% of your storage free.

Here’s how you can manage it:

• Go to System Settings > General > Storage
• Delete large files, apps, and caches you don’t need
• Move photos and videos to iCloud or an external drive

By taking these steps, your system can perform background tasks without delays.

⚙️ 2. Optimize Startup Apps

Too many startup programs can drag your system down. To reduce unnecessary background activity:

• Navigate to System Settings > General > Login Items
• Disable apps you don’t need launching at startup
• Restart your Mac to apply the changes

This quick fix significantly boosts boot speed and overall system performance.

🧠 3. Check for High CPU Processes

Sometimes, certain background processes consume a lot of CPU power. One common culprit is kernel_task, which is often linked to your Mac’s thermal controls.

To check:

• Open Activity Monitor from the Utilities folder
• Look for processes with high CPU usage
• Close apps that are resource-intensive

In addition, ensure your MacBook is placed on a hard, flat surface for better heat dissipation.

🔄 4. Reset SMC and NVRAM

Sometimes, deeper system resets are needed.

• Reset NVRAM: Shut down your Mac. Then, power it on while holding Option + Command + P + R for 20 seconds.
• Reset SMC: For M3 MacBooks, simply shut down, wait 10 seconds, then restart. The SMC resets automatically.

These resets can resolve strange glitches and restore performance.

🔧 5. Boot into Safe Mode

Safe Mode disables third-party extensions and runs diagnostics in the background.

• Restart your Mac and hold the Shift key during boot
• Let the system load, then restart normally

This trick helps identify software conflicts slowing down your device.

📲 Bonus Tips to Maximize Performance

Here are a few additional ways to keep your MacBook running at its best:

• Keep macOS updated for security patches and performance improvements
• Reindex Spotlight: Go to Settings > Siri & Spotlight > Spotlight Privacy, add and remove your drive
• Reduce animations: In Accessibility > Display, enable “Reduce motion” and “Reduce transparency”

These tweaks may seem small but can make a huge difference in performance over time.
