4. Scan for Malware or Disable Anti-malware software

Although Mac is renowned to be the safest system ever existed, there are some vulnerabilities that can be abused by virus developers to penetrate their software. Especially if they are faced by inexperienced and naive users. Any infections can lead to sudden changes, and if not deleted, they will repeatedly put on their settings no matter what you do to tackle the issue. We highly-recommend using SpyHunter for Mac that will help you maintain your PC clean and virus-free.

Another possible reason for receiving the “Safari can’t establish a secure connection” error is because anti-malware software uses its own firewall to increase defense against threats. However, this can conflict with inbuilt antivirus and issue some changes in the connection properties. Thus, you can try and disable your safety program for a while and see whether it rectifies the problem. If yes, then you should consider trying another app that will not have errors like that.
