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

That oscp server must be compiling a huge set of stats on application usage. That doesn't sound right, privacy-wise.

It probably just gets a fingerprint, or the cert’ information.

But when the endpoint is dying and it gets called every time you try to run any binary…
