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”

Well, you're using the wrong distributions then. Use something stodgy but solid like stable Debian or a recent but not bleeding edge version of Mint and you should not have all too many things on your shit list. It won't be empty - printing will still trip you up every now and then, just like it does everywhere else to give an example - but it will mostly ' just work' unless you're trying to install it on truly exotic (as in "released this week") hardware. The overall facepalm experience will be comparable to that on Mac OS, better than that on Windows. Add to that the fact that it is free in every sense of the word as well as the glaring and welcome absence of draconic "features" like the one discussed in this thread and those Linux distributions will start to look very tempting.

Debian has abysmal hardware support( well gpus mostly). They need to do something about their kernels, my RX5700XT is miles ahead with the current kernel compared to whatever debian 10 ships.
