safari can't establish a secure connection

Safari can't Establish a secure connection😟

This might fix it.

I ended up installing fresh OS X.

Turns out it was my mac antivirus that was causing the "Safari can't Establish a secure connection". All website are working after i disable the Web Shield in my antivirus setting.

From your Safari menu bar click Safari > Preferences then select the Privacy tab.

Click: Remove All Website Data

Then delete the cache.

Open a Finder window. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following

~/Library/Caches/com.apple.Safari/Cache.db

Click Go then move the Cache.db file to the Trash.

Quit and relaunch Safari to test.

If that didn't help, check System Preferences > Security & Privacy > Firewall > Firewall Options

Hello All,

I had the same issue. Chrome and Safari wouldn't open any https websites, error message : Safari can't establish a secure connection ...

I tried all solutions you can imagine , but no success.

and then ... I noticed my OS X time is not syncing with Apple too (time.apple.com) , so I put it on manual and changed the time to exact time manually

WOHOOO .. everything started to work , all security errors are gone, my anti-virus updated instantly without me touching it .

I am super happy 🙂

For anyone still having this problem, I found out that it was simply my date and time settings that had been reseted, and therefore I just had to manually adjust my calendar and time so that they corresponded with the certificats of all online servers.

I had the exact same problem. I also searched through multiple forums but could not find a solution.

It was not my internet provider because the same websites worked on other devices. So I uninstalled

avast and rebooted my mac and it worked. It turns out avast web shield was causing the problem.

Furthermore, apparently it is now more dangerous to use a 3rd party anti-virus like avast because 1) they

have access to areas of your computer that you really do not want anything other than your OS to have access

to and 2) hackers now only have to get into the software and that is in (They have already hacked the wifi protocol).

AVG was also hacked by the way so you might as well uninstall avast.

Hope this helps

The real issue, is that Apple is not updating Safari's security protocols to interface with websites that are enhancing their own. That's and understatement: the last time I received a Safari update was in August 2014. When I get the message on my desktop that a secure connection can't be established, I go to my tablet and guess what, I have a secure connection. If Apple were as diligent about keeping desktop users software up to date as they are developing new operating systems, there wouldn't be a problem, but, there's no money in it for them to upgrade my Safari 6.1.6 running 10.7.5.

Open safari > safari preferences > general > set safari opens with new window .

you must have enabled as : A new private window that is private browsing .

And in private browsing cookies are disabled , to run Facebook cookies must be enabled .

An article for private browsing is there : Safari 8 (Yosemite): Use Private Browsing windows

I solved this issue, but I'm not sure it's the solution for everyone. Try creating a new account on the Mac. Doesn't matter what kind but create a standard account first. Login with the new account. Launch Safari and visit the "problem" website in Safari.

If you don't get the error then the problem is something in the other account. I have not figured out what that might be.

I wanted to tell you the same guys but Farid7 was faster 🙂

If u are experiencing problems with safari telling u can not establish... also the battery problems like I did, after some time I realised it was all about the date and time.

I am happy too now 🙂

I was having the same problem. I have spent the last day trying to find the right resolution. I found a link to another forum and they recommended that you delete the

~/Library/Preferences/com.apple.security.plist

Have you made sure your software is completely up to date?

You should be at one of the following:

10.6.8

10.7.5

10.8.5

10.9.4

I had the same problem both on Safari and Firefox. I disabled "Web Shield" in my Avast anti-virus program, and now it works fine.

What I don't understand is, why it started creating this problem all of a sudden ? I have had Avast installed for weeks and was able

to go to any website.

a quick update:

Problem's still not solved, but I've established it's only confined to google.com sites (google, maps, youtube etc). iTunes is actually working fine.

I've also taken my router (airport extreme) out of the loop, so wired connection to modem now - same problem. Thinking about upgrading the modem in case that's the problem.

Any ideas?

I review the whole post on this subject. Nothing helped. :-(

"Can not connect to the server" message on each browser including Approte :-(

Mac Pro just upgraded to ElCapitan :-( as a result few apps do not work (VMWare, Apperture ... as most important to me)

I tried to get update for Apperture and .. failed. Appstore can not connect to the server. None of the browser can nonnect using SSL.

Basically dead in the water.

I had Norton Security installed - removed the whole application. - no help

I do not have any other AV software. I am going crazy here.

btw. the same network settings are on my laptop MacBookpro and there is no problem at all.

Please help
