Chrome Slow on MacBook Pro M1? Here’s How to Fix It

Your MacBook Pro M1 is a powerful machine — but even the fastest hardware can feel sluggish when Chrome isn’t running efficiently. The good news is that most Chrome performance issues on M1 Macs are solvable with a few targeted adjustments.

Whether you’re working with 8GB or 16GB of RAM, this guide will help you get Chrome running smoothly on your MacBook Pro M1.

Why Chrome Can Feel Slow on M1 MacBooks

Even though the M1 chip is incredibly fast, Chrome can still bottleneck your system for several reasons. First, Chrome is a memory-hungry application, and if you have many tabs open, it will consume RAM quickly. Second, some websites are extremely resource-intensive — especially those with heavy JavaScript, auto-playing videos, or live data feeds. Third, Chrome extensions can compound the problem significantly.

The M1 chip handles these challenges well when properly configured, but the default Chrome settings aren’t always optimized for Apple Silicon. Let’s fix that.

Start with Activity Monitor

Before making any changes, check what’s actually consuming your resources. Open Activity Monitor (Cmd + Space, then type “Activity Monitor”) and click the Memory tab.

Look at the “Memory Pressure” gauge at the bottom. If it’s yellow or red, your MacBook is running low on memory. Then look at Chrome’s memory usage in the list — if it’s using several gigabytes, you have a clear problem to address.

Also check the CPU tab. If Chrome processes are consistently using high CPU even when you’re not actively browsing, that’s a sign something is wrong.

Reduce Your Open Tabs

This is the single most effective fix for Chrome performance on any Mac, but it’s especially important on M1 machines with limited RAM. Every open tab consumes memory, even when you’re not looking at it.

If you’re someone who keeps 20+ tabs open, start closing the ones you’re not actively using. Bookmark important pages instead of leaving them open. Consider using a tab management approach where you only keep 5-10 tabs open at a time.

For M1 MacBooks with 8GB of RAM, keeping under 10 tabs is ideal. If you have 16GB, you can stretch to 15-20, but even then, fewer is better.

Enable Chrome’s Memory Saver

Chrome has a built-in feature called Memory Saver that automatically suspends tabs you haven’t used recently. This frees up RAM for the tab you’re currently viewing.

To enable it:

  1. Open Chrome Settings (Cmd + ,)
  2. Click on “Performance” in the left sidebar
  3. Toggle on “Memory Saver”

This is one of the easiest fixes that delivers immediate results. When you switch back to a suspended tab, it will reload briefly — but the tradeoff is worth it for the memory savings.

Audit and Remove Extensions

Chrome extensions can significantly impact performance, especially on M1 Macs where every bit of efficiency matters. Type chrome://extensions in your address bar and review what you have installed.

Ask yourself these questions for each extension:

  • Do I use this every day?
  • Is there a native app or website that does this instead?
  • Could I live without this?

Extensions that inject into every webpage (like password managers, grammar checkers, and shopping tools) are particularly heavy. If you’re on an 8GB M1 MacBook Pro, try keeping your extension count under 5.

Check Hardware Acceleration Settings

Hardware acceleration allows Chrome to use the M1’s GPU for certain tasks, which is generally good. However, it can sometimes cause issues.

To check or adjust:

  1. Go to Chrome Settings
  2. Click “System” in the left sidebar
  3. Look for “Use hardware acceleration when available”

If you’re experiencing visual glitches, frequent crashes, or high fan speeds, try turning this off. For most M1 users, keeping it on is fine, but it’s worth testing if you’re having problems.

Optimize Chrome for Apple Silicon

Chrome runs natively on M1 chips, but you should verify you’re not running the x86 version through Rosetta. Here’s how to check:

  1. Open Finder
  2. Go to Applications
  3. Right-click on Google Chrome and select “Get Info”
  4. Look at “Kind” — it should say “Apple” if it’s the native M1 version

If it says “Intel,” you may want to reinstall Chrome to get the native M1 version, which performs significantly better.

Limit Background Processes

Chrome continues running background processes even when you minimize it — checking notifications, updating extensions, and preloading pages. This can slow down your M1 MacBook Pro.

To limit this:

  1. Go to Chrome Settings
  2. Click “System”
  3. Disable “Continue running background apps when Google Chrome is closed”

This prevents Chrome from consuming resources when you think it’s closed.

Use an Ad Blocker

Ads and trackers are surprisingly resource-intensive. They load additional scripts, track your activity, and often auto-play videos. An efficient ad blocker like uBlock Origin can significantly reduce the work Chrome has to do on each page.

This is one of the few extensions that actually improves performance rather than slowing things down. By blocking heavy ad content, your pages load faster and use less memory.

Clear Cache Regularly

Over time, Chrome’s cache can grow enormous, consuming storage and sometimes causing performance issues. Clear it weekly or monthly:

  1. Press Cmd + Shift + Delete
  2. Select “All time” for the time range
  3. Check “Cached images and files”
  4. Click “Clear data”

Try Tab Suspender Pro for Advanced Control

While Chrome’s built-in Memory Saver is helpful, it doesn’t give you fine-grained control over when tabs suspend. If you need more power — especially on an 8GB M1 MacBook — consider Tab Suspender Pro.

This extension lets you:

  • Set custom idle timers for different tabs
  • See exactly how much memory you’re saving in real-time
  • Whitelist sites that should never suspend
  • Manually suspend any tab with one click

For users with limited RAM, Tab Suspender Pro prevents your MacBook from ever hitting the swap threshold, which is when performance really degrades. It proactively manages your resources instead of reacting to problems.

Restart Chrome Daily

Leaving Chrome running for days or weeks causes memory fragmentation and slowdowns. Make it a habit to quit and restart Chrome once a day. This clears memory and gives you a fresh, fast browser session.

Also, restart your MacBook Pro weekly. This clears system memory and helps everything run more smoothly.

Consider Your Workflow

If you’ve tried everything and Chrome still feels slow on your M1 MacBook Pro, think about whether you need Chrome for everything. Safari is natively optimized for Apple Silicon and uses less memory. You might use Safari for general browsing and keep Chrome only for specific tasks that require it (Chrome extensions, Google Workspace, etc.).

Summary Checklist

Here’s your action plan to fix Chrome on your M1 MacBook Pro:

  1. Check Activity Monitor to identify the problem
  2. Reduce open tabs to under 10 (8GB RAM) or 15-20 (16GB RAM)
  3. Enable Memory Saver in Chrome settings
  4. Remove unused extensions
  5. Verify you’re using native M1 Chrome
  6. Try an ad blocker
  7. Clear cache weekly
  8. Consider Tab Suspender Pro for advanced memory control
  9. Restart Chrome daily, Mac weekly

Most users see significant improvements after just a few of these changes. The M1 chip is more than capable of running Chrome smoothly — you just need to give it the right conditions.
