If you also found your Mac built into it, let’s try some convenient solutions to speed up Safari in macOS Catalina on Mac!

8 Tips to Speed ​​Up Safari in macOS Catalina on Mac

Since the problem may require you to take some drastic measures, you’d better talk about all the important things first.

So How Do We Speed ​​Up Safari for macOS?

First, we will try a series of tricks to fix slow Safari on Mac. We will get rid of all Flash plugins and extensions, to name a few. Although I never doubted their usability, they often slow down the web browser and even cause it to crash from time to time. We will also delete any existing cache along with any website data that may have accumulated over time. Just to keep it light and completely messy so that Safari runs as smoothly as it’s known. Having said that, let’s get started with the guide, shall we?

1. Disable Safari Extensions

Understood. Safari extensions go a long way in providing a more customized web browsing experience. As someone who likes personalized web browsing, I’ve always loved using them. While I’m not a big fan of these, I’m careful not to overdo it as using too many extensions can cause the web browser to slow down. Therefore, the first trick we will try is to disable all extensions or the ones you don’t use.

  1. Simply start Safari On your Mac -> Safari menu -> Preferences.

2. Now, click on Plugins tab and then uncheck the box for all Safari extensions or extensions you no longer use.

3. Remove All Website Data

Website data remains one of my goals when I notice that Safari is not performing as desired or seems rather slow. This is because they become problematic after a while if they are not removed frequently. That’s why I won’t let him escape.

5. Clear Safari History

Removing Safari history is one of the oldest ways to get rid of all the clutter available.

Note that it will remove Safari history on all devices synced with the same Apple ID. To do this, open Safari -> Safari Menu. Next, click Clear History. Later on, click the dropdown menu and select All History. Then click on Clear History to finish.
