    I get "drop-down" messages ( invalid web certificate ) when trying to acces websites in Safari that I visit frequently on my iMac running macOs Sierra. I suspect something is wrong and I can't find relevant issues elsewhere. I click cancel and leave the site. Attached jpeg shows "drop-down" in Danish language.

    Any suggestions ?

    Check the date and time of your Mac to see if it's accurate.

    maybe check here if the fingerprint of the certificate for that domain is matching what the site is reporting:
    https://www.grc.com/fingerprints.htm
    They are and should be unique.

    using an anti virus perhaps?

    Wauu - fingerprint and domain name is matching for the site I have chosen.

    But - thank you.

    Does that mean I could just select these and delete them without consequences?

    At least you figured out there's not something bad playing man in the middle or alike.

    Fantastic - problem solved.

    All affected sites were related to GlobalSign. I ran their command in terminal to clear cache and restarted the machine and everything was back to normal.

    And...no virus or anti-virus software on my machine :)

    I'm very impressed with your knowledge and I appreciate your effort to help.

    Thank you to all.

    Regards Lars

    Glad you got it sorted.

    Which command did you run from the GlobalSign site?

    I ran the command designed for OS X 10.12 Sierra.

    My OS version is 10.12.1 but I assumed the command would work for all 10.12.xx versions.

    Anyway I'm relieved.

    OMG It worked! This is the ONLY thing that worked. Putting that line in Terminal. So many people with this problem on the 'net and it's amazing the real answer isn't being put out there.

    I've had question marks for Walmart, Container Store, Houzz and IDK what else for probably 2 months now.
    IDK how to prevent this from happening again however.
