How to speed up Safari on Mac?

Here, we provide you with 9 feasible solutions to help you speed up Safari on Mac, thus fixing the Safari running slow on Mac problem. You can perform the following solutions one by one to check if any of them will work.

Check for network connection problems

If you find the website you open in Safari takes too long to load, or even fails to load, it's a good idea to check the network connection, and see if the culprit is not inside Safari itself. Sometimes, a bad network connection will lead to the unstable performance of Safari. So, whenever you feel Safari is slower than usual, check your network first.

Shut down unneeded apps and resource-intensive programs

Safari will run much slower than normal when you have countless applications or resource-intensive programs opened on your Mac. In this situation, those apps and programs take up the most CPU usage, and thus there's not much left for Safari. So, to speed up Safari on Mac, you can quit or force-quit those apps not actively used on the Mac Dock.

Also, if you want to sort apps and find those consume too much processing power and memory, use the Activity Monitor to help you, here's how:

  1. Go to Mac Launchpad > Others, find Activity Monitor, and launch it.
  2. In the Activity Monitor window, click on the CPU tab or Memory tab in the top menu.
  3. Select the process or app that uses a great amount of CPU or lots of RAM, then shut it down.

Close unnecessary tabs in Safari

When you are searching for information or just browsing interesting websites in Safari, you may open a lot of tabs without realizing it. Too many tabs open in Safari will get Safari running slow on Mac. Because this Apple's default browser keeps many of those tabs active in the background, even when you are not using them.
