10 Fixes When Safari Running Slow on Your Mac
If you have a lot of tabs open, close some of them
When you have a lot of tabs open in Safari, it can start to run slow. To help speed things up, close some of the tabs you’re not using. This will free up memory and processing power, making Safari run faster.
Try using a different DNS server
If you’re using Safari and you’re finding that it’s running slow, one potential fix is to try using a different DNS server. DNS is the system that translates website addresses into IP addresses, so it’s an essential part of browsing the web.
If your DNS server is slow, it can cause Safari to load slowly as well. There are a number of public DNS servers you can use, such as Google DNS or Cloudflare DNS. To change your DNS server, you’ll need to go into your network settings and update the DNS server address.
Check your extensions and plugins
If you’re noticing that Safari is running slowly on your Mac, one of the first things you should check is your extensions and plugins. While these can be very useful, they can also cause performance issues if they’re not up to date or not compatible with your version of Safari. Try disabling or removing any that you don’t absolutely need, and see if that speeds things up.
Check your computer for viruses
If your Safari browser is running slow, one potential reason could be that your computer is infected with a virus. Viruses can cause all sorts of performance issues on your computer, so it’s always a good idea to run a virus scan if you suspect that might be the case. There are a number of different antivirus programs available, so you can choose whichever one you prefer. Once you’ve installed the software, run a full scan of your system to see if any viruses are detected. If so, you can remove them and hopefully see a speed boost in Safari.
Use a private browsing window
When Safari is running slow on your Mac, one thing you can try is to use a private browsing window. This will create a new window that doesn’t track your browsing history or keep any cookies from your previous browsing sessions. To do this, simply click on the File menu and choose New Private Window.
If you find that your Safari is still running slow after trying a private browsing window, move on to the next fix.
Empty your caches
Assuming you’ve tried all of the other tips on this list and Safari is still running slow, one potential culprit could be your caches. Over time, these can start to build up and slow down your browser. Luckily, it’s easy to clear your caches in Safari. Just go to the Safari menu and select “Clear History and Website Data.” Confirm the action and your caches will be cleared.
disable location services
If you’re noticing that Safari is running slowly on your Mac, one potential reason could be that you have location services enabled. While location services can be useful in some cases, they can also drain your battery and slow down your Safari browsing experience. If you don’t need location services, you can disable them by going to your System Preferences and then selecting Privacy. From there, you can click on Location Services and turn it off.
Restart your computer
One of the best ways to speed up Safari is to restart your computer. This will clear out any junk that has accumulated in the Safari browser and allow it to start fresh.
