The suffocating feeling that someone looks over your shoulder is quite uncomfortable. The same is replicated by the nasty ad trackers who track your browsing activities and how you use content. As much as I want to not joke, you need to be aware of what really happens to your favorite sites.
Fortunately, Apple crac King is down to the scary sites that track your behavior, whether or not you click on their site. In addition, Apple's latest version of Safari includes Intelligent Tracking Protection 2.0, which examines and defends third parties as well as first-party potentials to track your browsing activities.
Therefore, Safari may fail while opening a suspicious or improperly crafted page. If you've met the "Cannot establish secure connection" error message with your frequently visited sites, you're not alone. Here are the best work solutions to help you fix that error and continue to surf peacefully.
1. Check for the correct certificate
To keep it simple, make sure you access the right site by clicking on the address bar. You should examine the URLs and look for the green lock icon in front of the site address. If it looks like gray, it may be a cleverly crafted phishing site with the exact logo and layout of your bank or another site you visit frequently.
2. Delete Browser History
The Safari option to delete the browser log is like a double-edged sword. Usually, the Clear Browser History option will remove the list of sites you visited. However, the latest iteration of Safari removes the related data, such as cookies and content on the respective sites.  “/>
Step 2: Select All History from the drop-down menu next to the word Clear. Then click Delete History.
3. Uninstall Suspicious Extensions and Plugs
Extensions, plugins and add-ons are like little helpers that speed up the process of performing specific tasks with a click or two. However, installing for many of them affects Safari's performance. So, it is only wise that you remove the unwanted and unused plugins or extensions.
Step 1: Click the Safari menu and select Settings.
Step 2: From the pop-up window, click Extensions to display the list of extensions you have installed for Safari. I didn't install any extensions. But if you see something, select and remove them.
4. Unblock All Cookies
It may be an honest mistake that you accidentally click on the box that appears just below the one that says – Prevent cross-site tracking. If this is the case, the box essentially blocks all cookies.
Step 1: Open Safari preferences and click Privacy.
10. Use Another Browser
If nothing works and you need to use a web browser, it's better to use another browser like Firefox or Chrome.
Continue Safe Browsing
If none of the solutions mentioned above work, the problem may be with the site. The installation of macOS is the last resort, and I bet it doesn't. One of the solutions mentioned above should work for your Mac. It is quite possible that the site you are trying to access is not available and is facing downtime.
