Ok, no problem. It would appear Globalsign's advice is out of date when it comes to macOS Sierra. Instead you should paste the following command line (it's all one line) into a Terminal window:


sqlite3 ~/Library/Keychains/*/ocspcache.sqlite3 'DELETE FROM responses WHERE responderURI LIKE "%http://%.globalsign.com/%";'


This just removes the expired Globalsign certificates from the cache.

Dear Trevoz

Thank you. Yes, I also saw this advice from "GlobalSign"

I am so clueless about the inner workings of computers that I have no idea where to enter the commands recommended

I get as far as "Utilities" > "Terminal" > and then ?

when I tried copy pasting the instruction to "delete both OCSP and CRL cache":

certutil -urlcache * delete

I get the message "command not found"


Tedious

Sorry to bother you with it

You did in fact select Solved on the correct post 🙂 Then gave me additional points with Helpful on another post 🙂

So fear not. My points cup is overflowing 🙂


It's not about points anyway. I get more out of answering the questions as I get to learn more about my secondary operating system - I run FreeBSD on most of my Mac Minis.

I've solved this.

What I suggest you do is open this path

~/Library/Keychains

There you may see multiple folders with GUID like names.

Replace the * in the command above with the name of the folder.

So for example I used


sqlite3 ~/Library/Keychains/698D32DB-5B41-5382-96B6-73BE3AC5E913/ocspcache.sqlite3 'DELETE FROM responses WHERE responderURI LIKE "%http://%.globalsign.com/%";'


See if this works for you
