8 Tips to Speed Up Safari in macOS Catalina on Mac

As the problem may require you to take some tough measures, it would be better if you talk about all the important things first up.

So, How are We Going to Speed Up Safari for macOS?

First things first, we are going to try out a whole host of tricks to troubleshoot the sluggish Safari on Mac. To name a few, we will get rid of all the Flash plug-ins and extensions. While I never doubt their usability, they often slow down the web browser and even cause it to crash at times. Besides, we are also going to wipe out all the existing cache along with all the website data that may have piled up over time. It’s just to ensure that Safari remains light and completely decluttered to run as smoothly as it’s known for. With that said, let’s get started with the guide, shall we?

1. Disable Safari Extensions

I get it. Safari extensions go a long in providing a more customized web browsing experience. As someone who loves personalized web browsing, I have always loved using them. Though I’m a big fan of them, I make sure not to overkill as using too many extensions can cause the web browser to slow down. So, the first trick that we are going to try out is to disable all the extensions or the ones that you don’t use.

  1. Now, click on theExtensions taband thenuncheck the boxfor all the Safari extensions or the ones that you no longer use.

After you have disabled extensions, force quit Safari. Simply click onApple menu -> Force Quit -> Safari -> Force Quit.Then, restart your Mac.

2. Disable Plug-ins

It’s no secret that plug-ins make web browser slow and even cause it to quit unexpectedly at times. Not to mention, they are also known to prevent downloading files sometimes. So, it would be better to disable them in favor of smooth performance.

  1. LaunchSafarion your Mac ->Safari menu -> Preferences.

  2. Now, click on theWebsitestab anduncheck the box to the left of the plug-in name.

Now, force quit Safari as usual. Then, launch it again to see if the web browser can run smoothly.

3. Remove All Website Data

Whenever I find Safari unable to deliver the desired performance or seem to be rather sluggish, website data remains one of my targets. It’s because they do become problematic after a while if not removed on a frequent basis. So, I’m not going to let it escape either.

  1. Open theSafariapp on macOS ->Safari menu -> Preferences.

  2. Now, click on thePrivacytab ->Manage Website Data. Then, click onRemove Allto eliminate all the stored data. In the end, click onDoneto finish.

4. Empty Safari Cache

It’s always advisable to remove cache frequently so that it doesn’t become problematic. If you hadn’t removed it for a while, chances are it might be the hidden culprit behind this whole mess. So, remove it sooner than later.

  1. Open theSafariapp on your Mac ->Safari menu -> Preferences.

  2. Now, click on theAdvancedtab and then check the box forShow Develop menu in the menu bar. After that, click on theDevelop menuat the top and selectEmpty Caches.

5. Clear Safari History

Removing Safari history is one of the oldest ways to get rid of all the existing clutters. So, in a situation where a speedy Safari is more important than the piled-up history, you shouldn’t hesitate to wipe out all the data. Keep in mind, it will remove Safari history on all the devices synced with the sameApple ID. To do it, open theSafari -> Safarimenu. Then, click onClear History.After that,click on the drop-down menu and choose All History. Then after, click onClear Historyto finish.

6. Update DNS Setting on Your Mac

If you are still struggling to speed up Safari on your Mac, update the DNS setting. For those unfamiliar, it stands forDomain Name Serverthat allows users to connect to websites using domain names. In other words, it’s known as the phonebook of the Internet.

  1. Next, select how your computer connects to the Internet (i.e Wi-Fi, ethernet). Then, click on theAdvancedbutton.

  2. Now, click on theDNS tab. Under the DNS servers section, click on the“+” or “-” buttonto add or remove the IP address of a DNS server.

Just in case, you are using more than one DNS server, you can drag the addresses to change the order. Also, if you don’t know which DNS server to use, check out our list of thebest free DNS serversto get started.

7. Flush Out DNS Cache

Flushing out DNS cache has done the trick many a time for me in fixing the Safari running slow issue on Mac. So, I’m banking on this hack again to resolve the problem. To get it done, you have to use the following Terminal commands.

Simply launchTerminalon your Mac and then enter the below-given command and hit the return key.

Note:Also, try to turn off DNS prefetching as it has the knack of speeding up the web browser. To disable DNS prefetching, launch Terminal and then enter the below-given command: After that, hit the return key.

In the end, quit the Terminal app.

8. Update Software on Your Mac

If you have followed the recent trend, you might already be whispering with something like “This could very well be the answer to this problem!” Well, it just goes on to explain how much Apple’s ecosystem (including iOS) is embroiled with issues in recent times (i.eApproved not workingandMessages not syncing with iCloud.) So, do not forget to update macOS. Click onApple menu -> System Preferences -> Software Update.Now, follow the usual steps to update macOS Catalina.
