How to fix MacBook internet slow

If the internet is slow on your Mac but not on other devices or just generally sluggish, these tips will help you solve the problem. Let's get started.

1. Check with your service provider

Before diving into technical troubleshooting tips, your first call should be to check with your internet provider. Ask if there are any outages or network and service issues. If they report problems in your area, you must wait it out. However, if there are no outages or issues with your service provider, jump to the next tip.

2. Restart your Mac and your router

Sometimes a quick restart is all you need to solve connectivity issues. First, start with restarting your Mac — this can help solve multiple problems, including Mac's slow internet.  Simply press Restart from the main Apple menu.

Restarting Mac and router

While your Mac is booting back up, restart your router. It will help to clear router cache. How to do this will vary depending on the origin and model; if your router doesn't have a restart button, simply unplug it for around 60 seconds and plug it back in.

3. Check for updates

If restarting your Mac and router didn't help speed up the internet on your Mac, it's time to check for available system updates.Keeping on top of macOS Software updates will help you address glitches and bugs like internet connection issues and also enhance performance and security.

If it's been a moment since you last updated your Mac, here's a quick reminder:

System Preferences - Software Update

  • Select System Settings from the main Apple menu.
  • From the sidebar, press General > Software Update.
  • Install any updates if available.

4. Run maintenance scripts 

Running maintenance scripts on your Mac can help to remove a build-up of temporary data, Apple cache and useless system logs. This will not keep your Mac in tip-top shape, but it can help to resolve many system issues, like slow internet.

The Maintenance module in CleanMyMac X is the perfect tool for the job. You can run scripts in just a few clicks and enhance your Mac's performance simultaneously. Download the free version first, if you haven't already, then follow these easy steps:

Maintenance Scripts in CleanMyMac X

  • Open the app and find Maintenance in the sidebar.
  • Press View All Tasks.
  • Select Run Maintenance scripts from the list, along with any other items you need.
  • Press Run.

5. Check for browser updates

Although most browsers issue updates automatically in the background, this can often fail. If your browser is out of date, this might be the reason you're having issues.

In the example below, I'll show you how to check for updates in Chrome.

Chrome browser updates

  • With Chrome open, select the main Chrome menu > About Google Chrome.
  • Under the About Chrome section, you'll see if your browser is up-to-date.

While we're on the subject of browsers, it's also worth closing open tabs. Too many open tabs will also dramatically slow your internet down.

6. Check for corrupt browser extensions

When your MacBook Pro has slow internet, it's worth checking to see if outdated or corrupt browser extensions and plugins are the root cause. Here’s how to check Chrome extensions:

Chrome browser extensions

  1. With Chrome open, select the main Chrome menu.

  2. Press Settings > Extensions.

  3. Toggle all your extensions off, close your browser and try turning extensions back on, one by one.

  4. If you find the extension slowing your Mac down, remove it.

  • In the sidebar, uncheck all your extensions.
  • Close your browser and turn your extensions back on, one by one.

7. Remove your Wi-Fi network

Another tip to fix your MacBook's slow internet is to forget your Wi-Fi network and then reconnect. It's important to mention that this will completely remove your Wi-Fi network, and you'll need to know the password to reconnect.

System Preferences - Wi-Fi

  1. Select the main Apple menu > System Settings > Network > Wi-Fi.

  2. Select the Details button next to your Wi-Fi name.

  3. Press Forget This Network.

  4. Back in the main Wi-Fi menu, locate your Wi-Fi network from the Other Networks list and select it. You'll need to enter your password to join it again.
