Safari can’t open the page because Safari can’t establish a secure connection

A friend has started having a problem on her Mac connecting to certain web sites that she has connected to many times in the past. The Mac throws up this error…


Safari can’t open the page because Safari can’t establish a secure connection


I tried to help me by changing her DNS servers from Open DNS to Google’s. No solution.


I used Firefox to find out what the host servers were and changed the Trust settings on those certificates to Always in Keychain. No luck.


I removed the cookies and cache data associated with the sites. Restarted Safari. Nope.


I tried changing the settings in iPv6 to manual but the fields didn’t automatically populate with the Router, iPv6 Address and Prefix Length so it wouldn’t let him proceed and had to cancel.


She is running an older iMac, Yosemite, Safari 10.1.2. Upgrading to a new OS isn't a desirable option because she is using quite a bit of older software that would be rendered useless.


Anybody have any suggestions?


Thanks, Welles

Are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply.

Hi Eric,


I tried out your suggestions yesterday. The problem still occurred in Safe mode and a new Administrator account. So I ran Etrecheck. Here's the report.

I noticed the anti-virus info you asked about in the report but had forgotten to look for it myself.


If you wouldn't mind taking a look to see if anything pops out I'd be appreciative. My last two strategies are to run DiskWarrior (just because I've kept up with the latest since the late 1990's and it can't hurt). After that the only thing I can think of is to boot into recovery mode, use Disk Utility and run first aid just to see if anything gets fixed, repair permissions and then run the reinstall OS.


If you have any other suggestions I'm open for guidance. Thanks!

Welles

That was going to be my "fix" for the problem but I cant find anything I can update to. I am running yosemite. Havent been offerred any further updated OS from Apple, so I havent done any. Really didnt need to until this issue with Safari came up. I dont want to change servers, I like Safari. Cant just update it though. Any links to any OS updates that are compatible with a mid 2010 macbook pro?
