fix-safari-running-slow-on-Mac1.jpg

Safari as the Mac default browser, is developed by Apple based on the WebKit engine. Apple touts Safari as the fastest browser out there, which may be true on iOS, but it doesn't work the same way on Mac because Safari is just too slow. Sometimes a webpage loading seems like taking forever, which is so frustrating. And you won't be able to navigate back and forth between pages. Why is Safari running so slow on Mac?  Here we listed some possible reasons and shared some tips to make your Safari faster.


1: Overworked Cache and History


Like all other browsers, Safari stores information about every website you visit as browsing history automatically. Elements of those websites like images and html files are saved to cache so that pages load faster next time, which puts an additional burden on the browser. Overworked Cache and History may be the biggest 'culprit'of slowing Safari. So, try getting rid of the dead weight and see if Safari is still slow afterwards. Here's how to erase the data in the cache so that Safari can work faster.


Clean Up History in Safari


1. Open Safari

2. Find History in the menu bar (or click Safari then choose Clear History)

3. Click Clear History at the bottom

4. Select the time span and hit the Clear History button.

 2: Buggy and Bad Extensions


Extensions enable users to tailor Safari functionality and behavior for individual needs or preferences, and let you do a ton of convenient extras in a browser, like storing passwords or translating words with a click.
