Update Safari
Make sure that you are using the latest versions of Safari. Since Safari is a part of the macOS software, updating your Mac’s software will also update Safari. Here is how:
- Open System Preferences.
- Click Software Update.
- This will check for updates. If your Mac says that your Mac is up to date then Safari is up to date too. If not, click the Update Now button and then follow the onscreen instructions.
If you are running macOS High Sierra or earlier, you will need to open the App Store app on your Mac.
Remove cookies, cache, and other data
When you visit a website, Safari saves some information from the website in its cache and cookies. Removing them may resolve this issue. Here is how:
- In Safari, click Safari and Preferences.
- Click Privacy.
- Click the Manage Website Data… button.
- A new window will appear saying Loading Website Data. This may take a few minutes. Wait for Safari to load website data.
- Then you have two options:
- If you are having this problem with specific websites, you can remove their data individually. In the search field, enter the name of the website, then select the website and then click the Remove button.
- If you want, you can also remove all website data, if you are having this problem with a lot of websites, and removing them individually may be difficult. You may try this option instead. Click the Remove All button.
- Then click Done and exit Preferences.
Please note that when you remove this, some of your site settings will be deleted. Also if you were signed in, you may also need to re-sign in again.
Third-party security software
Some third-party security software, such as firewalls, antivirus, may cause this problem. For example, some Avast Antivirus users have said that turning off the Web Shield setting fixed this problem for them.
What you can do is, to isolate the problem, to turn off your antivirus or similar software completely but temporarily. Then try to open the web site that gives this error. If now you can open the website, you know that your antivirus software is the problem. If this is the case, you have a few options:
- Contact the virus software vendor for further help.
- Permanently disable the software.
- Keep adjusting and customizing your antivirus settings (e.g., turning off Web Shield) until you get rid of this problem.
If turning off your antivirus software does not change anything, this means that your problem is elsewhere. You can turn it back on if you want.
Apple logins
If you see this error message when you attempt to log into the Apple services such as iCloud, Apple Store, Apple Developer, or Apple Communities, the problem may be Apple’s security certificate.
- Visit the Apple certificate page (link).
- Under the Apple Intermediate Certificates section, download Apple IST CA 2 – G1 Certificate by clicking it.
- When the download is completed, double click it to install or you can drag the certificate file onto the Keychain Access icon. This certificate will add the certificate to Keychain. If asked, enter your admin password.
- When you are done, click OK.

Now try to open the website again.
I have been using Wikipedia for years, suddenly “Safari can’t establish a secure connection to Wikipedia” etc. I have changed nothing – no OS updates (using 10.6.8), no new 3rd. party software. Both my iMac 9.1 and MacBook Pro 7.1 are locked out of Wikipedia – yet my iPad Air II is unaffected.
My Firefox browser also refuses to connect.
So, why will Safari on iOS open a
specific website, but Safari on Mac
cites ‘unauthorized signature on Security Certificate’ & won’t open that same site?
I performed your suggestions to the point and still I’m getting the same error. This is driving me nuts. This started after I reset my iMac to its factory state. I upgraded my system up to OS X Lion (10.7.5) I need full access to the internet in order to collaborate with fellow musicians in Facebook, Tweeter etc. Please help!
Same problem here. I wiped my MacBook early 2008 and clean installed snow leopard and now this. Did you find a solution? I been working on this prob for days…
Thank you so much for publishing this article! Turns out my issue was because of a third party security software I had downloaded. I got the issue fixed! Thank you so much again!
If I clicked on a suspicious link on a text unintentionally but got prompted with the Siri couldn’t establish a secure connection does this mean that I have visited the website and I’m compromised or does this imply that I’ve not been on the site thanks in advance
After a disk wipe and new install on iMac G5 ppc running Leopard.
Safari will connect to google fine and bring up all search results okay. But any attempt to connect to any of the sites thereafter results in the error, cannot connect to server.
I’m having the same issue after my reinstall of snow leopard on my early 2008 macbook. Did you find a solution?
The thing is I am aware of what I am doing and I really want to hit that website since I’m doing testing … need a way to bypass that or accept the certificate
Under: Remove cookies,cache, and other data.
Will not allow me to remove a specfic website. I highlight it, click remove, and then done.
It will remove from the screen and then sometimes comes back a second time to be deleted.
before I hit done. The when I try to visit the site…error message is still there. I try it again, and when I go back, my specfic website is still there. Why won’t it disappear and stay gone? Thank you in advance for any information you can provide to help me with this problem. Ron
