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

My MacBook is basically unusable right now. This appears to be the reason. Is there any way to fix it without installing little snitch?

Edit: working as usual now, moments after i wrote this. But seriously Apple, how can you allow this to happen? Your services hanging should _never_ prevent my device from running things locally. This is seriously making me reconsider my next computer purchase.

I don't know if the slow downloads of Big Sur are related, but the underlying problem is that ocsp.apple.com[1] is fubar, and certificate revocation lookups are failing.

EDIT: This might indeed be Big Sur-release-day related. Most certificate revocation failures are "soft", but with ocsp.apple.com black-holed in /etc/hosts I can't resume downloading the update.

Apparently you can set ocsp.apple.com to 127.0.0.1 in your /etc/hosts

This is really terrible, but at least the workaround is simple.

Add the `127.0.0.1 ocsp.apple.com` line to your /etc/hosts file.

Turn off your internet, open the app, turn it back on.
