How to speed up Safari on Mac

3 min read

Is Safari running really slow on your Mac? Well, it’s no secret that Apple's default browser isn't perfect.

Safari is not immune to problems, and over time its performance can suffer unless you follow a couple of simple measures to make sure it stays running like clockwork. 

If the page load times are getting slower or you’re experiencing browser crashing and freezing, you've come to the right place. 

How to check if Safari is down today

Is Safari down today? It's a good question. You can check Apple's online system status page to see if they are experiencing any server or system issues.

Today, everything is working fine, but if you did notice an issue, this would be indicated by a red outage indicator.

You cannot do a lot in these cases, just wait and hope the servers are fixed quickly. 

Now we've checked the servers, making Safari faster is next on the agenda. 

How to speed up Safari

1. Close all tabs 

Some browser tabs use more memory than others, causing the “This webpage is using significant energy” message to appear. Even the pages you’re not currently using consume CPU resources and may slow down your browser. So, if Safari is slowing down, bookmark the important pages and close the rest of the tabs. This should speed things up a bit. 

2. Turn off or remove Safari extensions 

Extensions eat up resources — removing unused extensions is a sure way to improve performance. Here's how to do that:

How to turn off Safari extensions

  1. In Safari, select the Safari menu and press Preferences.

  2. Select Extensions from the tab.

  3. Go through your list and choose any Extensions you no longer need.

  4. Then, press Uninstall and follow the on-screen instructions. 

3. Remove Safari Cache

Removing a build-up of cache is another quick way to improve Safari performance drastically. Here's how:

Safari - Advanced settings window

  1. Open Safari and select the Safari menu.

  2. Choose Preferences and select the Advanced tab.

  3. At the bottom of the window, locate the Show Develop menu in the menu bar and check it.

  4. Now, select the Develop menu from the top menu bar and choose Empty caches.

4. Optimize your macOS

Another reason that Safari is running really slow could be that your Mac is not fully optimized, making programs and applications run slower than usual. 

When did you last run some basic maintenance tasks on your Mac?

Over time these items can seriously make your Mac slow and sluggish:

  • Lack of available RAM

  • The build-up of DNS cache

  • Broken disk permissions

You could spend all day attending to these issues manually, or you could use a dedicated tool like CleanMyMac X. That's what I prefer to do. CleanMyMac X comes with a Maintenance module that helps improve system performance; it’s simple to use and quick to get to work; take a look.

How to quickly run Mac maintenance:

  3. Choose tasks from the list you want to perform and press Run.

5. Remove Safari history & cookies

Removing all history and cookies may help improve Safari performance. Here’s how to do that:

How to clear Safari history and cookies

  • Open Safari and select the Safari menu.

  • Select Clear History, then select All History from the dropdown and press Clear History.

To remove cookies in Safari:

Safari privacy settings

  • Open Safari and select the Safari menu.

  • Click Safari Preferences.

  • Go to Privacy.

  • Click Manage Website Data.

  • Click Remove All to delete cookies.

6. Disable autofill 

Autofil can be a handy tool, but the more data you have stored in autofill, like passwords and logins, the more resources Safari needs. Disabling autofill will help make Safari run faster.

How to disable autofill in Safari

  1. In Safari, select the Safari menu.

  2. Select Preferences, then select the Autofill tab.

  3. Select Edit next to any item to view and remove your autofill data.

  4. Then uncheck which autofill web forms you no longer want. 

7. Reset Safari

If you've tried all of the above, but Safari is still slow, you can try resetting the browser. 

You can do this quickly with CleanMyMac X, which helps revert Safari to its original state.

  1. Launch the app, then select Uninstaller from the sidebar.

  2. Search for Safari in the search bar.

  3. Once selected, press the dropdown arrow and choose Reset.

  4. Now press Reset at the bottom.

It's really that simple. 

These tips should have helped you speed up Safari. Ensure you keep up the regular maintenance and optimization; these will help you keep Safari running smoothly. Happy browsing.
