Good day Nairaland, please come to my aid today. My MacBook, MacOS Sierra (Early 2011) is not able to visit a website and I'm getting SSL error on any browser I tried using, either safari, chrome and Mozilla. On Google Chrome, it shows, "Your connection to this site is not secure", I have disabled my Norton licensed anti virus and I have also done most of Mozilla solutions, all to no avail. Could my MacOS version be the cause or it's from the website, my version is 10.12.6, a friend of mine said it could be upgrading issue because this version does not receives update anymore, I've also visited this website with https and http. If I successfully bypass it, it won't still allow me to login to the website with my correct email and password.Please I need your help urgently
