I understand. Safari extensions do a lot to provide a more personalized browsing experience. As someone who loves personalized web browsing, I’ve always loved using them. While I’m a big fan of them, I’m careful not to overdo it as using too many extensions can cause the web browser to slow down. so the first trick let’s try is to disable all extensions or the ones you don’t use. Instead, they should fix Safari complications like super slow Safari on macOS Big Sur/Catalina or Mojave. Safari won’t open, so Safari won’t load a page, browsers won’t work after Safari won’t load on MacBook, and more. There is a way you can get solutions to all these problems. So let’s start with them to accelerate up the slow internet connection on Mac.

Make sure auto proxy detection is unchecked

This setting is useful for privacy reasons, but the proxy server and some settings could be creating the slow internet issue. Unchecking Auto Poxy dictation can help bypass the proxy server, or Mac users can get direct internet connectivity if the proxy server is not available to them.

Turn off Safari Mac search suggestions

Search Suggestions improve the user experience as you connect to your Apple device. Search suggestions use Siri search on all your Apple devices such as iPhone, iPad, Home pod or Apple Watch. As per your Favorites search, you can also quickly get the exact location on your Mac. sometimes that feature it’s useless; by disabling “Safari Search Suggestions” as a result you can get more benefits on a slow safari or mac system.

Disable DNS Prefetch on Safari Mac

Does your Mac send DNS queries to the network through the router and your router is unable to process these queries in a timely manner? As a result, you will get a slow response from the internet. With DNS prefetch enabled, your Safari browser on Mac will send a DNS request to load the website the first time. So, disabling DNS prefetch on your Mac Safari is a great solution if this is happening to your system. Below, I recommend trying alternative methods to disable DNS prefetch on a Mac or Macbook running any macOS.

Change DNS Service Provider for Safari Slow:

By default, our DNS settings are provided by the ISP. Instead, this time we’ll try to use public DNS, which can boost Safari. The best DNS server is Google DNS; Probably everyone, including me, uses Google DNS. This action not only helps with Safari but also provides the solution for How to fix slow internet on mac?

Open empty page in Safari: no more loading every time

I also had issues with slow new tabs. We fixed it by opening a blank page instead of the home screen. The Safari browser has many hidden customizations that most Safari users are not aware of.

Open Spaces is a great tip to quickly browse and open on your Mac. Follow the steps below,

Force close and relaunch with “Shift” key

Your Safari browser is slow because the affected website is opening in the background; Some lagging websites are consuming more memory than your Mac which is the cause of Safari performance slowdown. To find out quickly, Mac users need to force quit Safari and restart with Refresh Safari Storage.

Test other Safari plugins and add-ons

An outdated or unsupported Safari extension installed on your Mac results in a slow browsing experience. So I recommend disabling the Safari extension or waiting for an update from the Mac App Store. From experience, some extensions cannot load websites like YouTube in a standard browser, but Private Browsing allows websites to be opened. As the installed extension will not load in Private Browsing, it is proven that you have a problem with the extensions.
