If you are seeing the "Safari can't establish a secure connection" error on your Mac, it means that Safari is unable to connect to the website you are trying to visit securely. Here are some things you can try to troubleshoot the issue:
- Check your internet connection: Make sure that your Mac is connected to the internet and that your internet connection is stable.
- Check the website URL: Make sure that you have entered the correct website URL in the address bar. If you have entered the URL correctly, try accessing the website using a different browser to see if the issue persists.
- Check the date and time on your Mac: Make sure that the date and time on your Mac are correct, as an incorrect date or time can cause issues with SSL/TLS certificates.
- Clear your browsing data: Clear your browsing data, including your cache and cookies, and then try accessing the website again.
- Check your security software: Your security software or firewall may be blocking the website you are trying to access. Try temporarily disabling your security software or firewall and then try accessing the website again.
- Check for updates: Make sure that you are using the latest version of Safari and that your Mac is up to date with the latest software updates.
If none of these steps work, you can submit the issue to apple. This is for educational purposes. Watch the video below for more information.
