Understanding Why Your MacBook is Running Slow in 2025

Before we dive into fixes, let’s understand why MacBooks slow down. The reasons have evolved over the years, but the core issues remain surprisingly consistent:

The Modern MacBook Slowdown Formula

Based on my analysis of thousands of slow Macs, here’s what’s killing your performance in 2025:

• Heavy data and media files (50%): 4K videos, high-resolution photos, and large applications
• Unnecessary apps and processes (30%): Background apps, launch agents, and memory leaks
• Browser data and extensions (20%): Too many tabs, resource-heavy extensions, cached data

MacBook Air vs MacBook Pro: Different Performance Challenges

While both suffer from slowdowns, they have unique characteristics:

MacBook Air:

• More prone to thermal throttling due to fanless design (M1/M2/M3 models)
• Limited RAM options (8GB base is often insufficient for 2025 workloads)
• Storage space constraints (128GB/256GB base models fill quickly)

MacBook Pro:

• More powerful but can still be overwhelmed by professional workloads
• Higher RAM capacity but users tend to push limits with creative apps
• Better cooling but can still suffer from dust accumulation

Step 1: Master Activity Monitor – Your MacBook’s Performance Dashboard

Before making any changes, you need to understand what’s actually slowing down your MacBook. Activity Monitor is your built-in diagnostic tool that reveals exactly which processes are hogging resources.

How to Open Activity Monitor

The fastest way: Press Command + Space, type “Activity Monitor,” and hit Enter. This powerful utility shows you everything running on your MacBook in real-time.

Understanding the Five Critical Tabs

CPU Tab: Finding Process Hogs

Click the “% CPU” column to sort by usage. Any process consistently using over 80% is a problem. Look for apps under your username first – system processes like kernel_task are usually normal.

Key Metrics at Bottom:

• System: macOS processes (should be under 20%)
• User: Your apps (varies by workload)
• Idle: Available capacity (below 20% = overloaded CPU)

Quick Action: Select any runaway process and click the stop button (X icon). Choose “Quit” first, only use “Force Quit” if unresponsive.

Memory Tab: The Most Important Indicator

Ignore the numbers – focus on the Memory Pressure graph at the bottom. This color-coded graph tells you everything:

• Green = Healthy: Your MacBook has plenty of RAM available. No action needed.
• Yellow = Constrained: macOS is compressing memory. Close some apps or browser tabs.
• Red = Critical: System using disk as virtual memory (very slow). You need more RAM or fewer open apps.

Critical Metric: If “Swap Used” is constantly changing and high (several GB), your MacBook is struggling with insufficient RAM.

Energy Tab: Battery Life Killers

Essential for MacBook users. The “Energy Impact” column shows current drain, while “12 hr Power” reveals consistently power-hungry apps.

Common Battery Drainers:

• Chrome (notorious for high energy use)
• Video conferencing apps (Zoom, Teams, Meet)
• Apps preventing sleep
• Background sync services

Disk Tab: Storage Activity

Shows read/write activity. High constant activity when you’re not actively using apps indicates:

Common Causes:

• Spotlight indexing (mdworker processes)
• Time Machine backing up
• Cloud services syncing
• Low memory forcing swap file usage

Network Tab: Bandwidth Usage

Identifies apps using your internet connection. Useful for finding:

What to Look For:

• Unknown processes with high data usage (potential malware)
• Cloud backup services saturating bandwidth
• Apps downloading updates in background
• Hidden cryptocurrency miners

Step 2: Five Quick Fixes That Make an Immediate Difference

These software adjustments take minutes to implement but can transform your MacBook’s performance. They target the most common causes of slowdowns without any risk to your system.

1. Manage Startup Items – The Silent Performance Killers

Every app that launches at startup slows your boot time and consumes resources all day.

How to Fix:

1. Go to System Settings > General > Login Items & Extensions
2. Remove unnecessary apps from “Open at Login” with the minus button
3. Critical: Check “Allow in the Background” section
4. Toggle OFF any apps you don’t need running constantly

Pro Tip: The “Allow in the Background” section is often overlooked but contains the real resource hogs – helper apps that run even when the main app is closed.

2. Reduce Visual Effects – Free Up GPU Resources

macOS animations look nice but consume CPU/GPU resources, especially on older Macs.

How to Fix:

1. System Settings > Accessibility > Display

• Turn ON “Reduce motion” (eliminates zoom animations)
• Turn ON “Reduce transparency” (removes blur effects)

1. System Settings > Desktop & Dock

• Turn OFF “Animate opening applications”
• Change minimize effect from “Genie” to “Scale”

3. Restart Your MacBook – The Simple Reset

Macs can run for months, but this causes memory leaks and cache buildup.

How to Fix:

1. Save all work and close apps
2. Apple Menu > Restart
3. For Apple Silicon Macs: This also resets system controllers
4. Schedule weekly restarts for consistent performance

Why This Works: A restart completely frees all RAM and clears temporary files that accumulate over time. It’s the simplest performance fix.

4. Update macOS and Apps – Performance Patches

Updates contain crucial performance fixes and security patches.

How to Fix:

1. System Settings > General > Software Update
2. Install all macOS updates
3. Update all App Store apps
4. Check for updates in non-App Store apps
5. Enable automatic updates for convenience

5. Optimize Spotlight – Stop the Hidden CPU Hog

Spotlight’s mds_stores process can consume massive CPU, especially after updates.

How to Fix:

1. System Settings > Siri & Spotlight
2. Click “Spotlight Privacy” at bottom
3. Add folders that don’t need searching (Downloads, Developer files)
4. Exclude external drives and backup volumes

Important: Never disable Spotlight entirely – it’s integrated into many system functions. Just exclude folders with frequently changing files.

Step 3: Strategic Storage Management – The Hidden Performance Killer

Here’s what most people don’t realize: your MacBook needs free space not just for saving files, but for basic operation. When your disk gets too full, performance crashes dramatically.

Why Your MacBook Needs 15-20% Free Space

System & Apps    Your Files    Working Space    FREE (Required)

macOS uses free disk space for:

• Virtual memory when RAM is full
• Temporary file operations
• System caches for speed
• File system operations

Without it, your MacBook grinds to a halt.

Check Your Storage Status

Apple Menu > System Settings > General > Storage

• Over 20% Free: Optimal performance
• 10-20% Free: Acceptable but monitor
• Under 10% Free: Critical – performance severely impacted

Smart Storage Cleanup Strategy

1. Use Built-in Tools First

• Storage Management suggestions (Store in iCloud, Optimize Storage)
• Empty Trash automatically (30-day setting)
• Review Large Files section

2. Manual Cleanup Hotspots

• Downloads folder: Installers, zips, old files
• Desktop: Everything here uses RAM!
• Old iPhone/iPad backups: ~/Library/Application Support/MobileSync/Backup/
• Time Machine local snapshots: Terminal command tmutil listlocalsnapshots /

3. Find Duplicates in Photos

• Photos app now has a Duplicates album in sidebar
• Can save gigabytes with one click

Advanced Storage Optimization

Move Large Libraries to External Drives

Photos Library:

1. Drag Photos Library.photoslibrary from Pictures folder to external drive
2. Hold Option while opening Photos app
3. Choose “Select Library” and pick the new location

Music Library:

1. Copy Music folder to external drive
2. Open Music app with Option key pressed
3. Click Choose Library and select new location

Note: You’ll need to keep the external drive connected when using these apps.

Step 4: Memory Management – RAM Optimization Techniques

RAM is your MacBook’s short-term memory. When it’s full, your system slows to a crawl.

Understanding Memory Pressure

As mentioned earlier, the Memory Pressure graph in Activity Monitor is your best indicator:

• Green: You’re good
