    Unbelievable. When I read the tweet (tried to post here as well), I suddenly realized why my Mac was unresponsive an hour ago.

    Here is another tweet that describes the problem in more detail:

    > I am currently unable to work because macOS sends hashes of every opened executable to some server of theirs and when `trustd` and `syspolicyd` are unable to do so, the entire operating system grinds to a halt.

    EDIT:

    As others pointed out, I put this to my `/etc/hosts` file and refreshed it like so:

        sudo emacs /etc/hosts # add `0.0.0.0 ocsp.apple.com` 
    sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder # refresh hosts

    Note that it's ocsp.apple.com, not oSCp.apple.com.

    dns is case insensitive

    OP was commenting on the order of the S and C

    parent is using case to highlight a typo in the domain name, not to imply that the problem is with the case.

    I'm sure if the SCP Foundation gets involved in filtering our applications, they have a very good reason, like keeping Zalgo out of our reality.

    "oSCp".ToLower() != "oCSp".ToLower()

    it's transposed, not case difference

    I would want to see what applications foundation is hiding from us. Like a FOSS version of Windows 10

    Ahh, thanks for the hint. It was a bad typo, but I can't edit my post anymore.

    Edit:

    Just reached out to Dang with a request to correct my typo.
