macOS unable to open any non-Apple application

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

I started panicking mildly thinking my drive was failing or something.

And just before this, I finally managed to fix Spotlight pegging one core at 100% constantly. Next thing, I reboot into a laggy system. macOS is my favorite OS, but the shit I put up with... it's basically an abusive relationship at this point.

Idk, the several Linux distros I’ve used recently, and Windows, have a much longer list of “shit _I_ put up with”

Can you really think of a single thing worse than this?

Computer failing to turn on as a buggy, mandatory update has replaced broken or replaced a driver with a non-functional one.

Fair enough, but that's not a typical experience on either Windows or Linux in this decade - if that's happened to you, then I think you've just been incredibly unlucky.

Disagree with Linux. I make an LVM snapshot before making any attempts to upgrade the graphics driver. It's a disaster. And don't say proprietary code, that's beside the point. Windows runs drivers in a way that one that crashes can be restarted without bringing down the kernel or the whole system.

FYI I've had the issue you describe half a dozen times with CentOS but literally never with Arch Linux (on both machines with similar nVidia cards, using the proprietary driver). In general I'm pretty impressed with Arch's package quality, I seldom encounter any issue and when I do it's patched very quickly.
