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”

The thing you get with Linux is "more _predictable_ shit to deal with", not "less shit to deal with", no large capable desktop OS is perfect and never will be.

Anxiety from what Apple's agenda will do to your computer next update? anxiety from if a 1hr windows update is awaiting you when you turn your pc on? ... Linux awaits.

Linux awaits and then when it comes it borks WLAN driver, because canonical decided to replace a perfectly working one with WIP FOSS alternative, forcing users to switch to cable LAN until it reached feature parity.

Linux awaits and then when it comes it borks AMD driver, because AMD decided not to support older cards on the new FOSS driver, and the old perfectly working driver is not compatible with modern kernels, driver ABI be dammed.

Linux awaits and then when it comes it breaks hard disk encryption forcing a full install, and feeling lucky that I actually backup /home regurlarly.

Linux awaits and then when it comes half of the stuff doesn't work in Wayland.

Eventually I rather just deal with macOS, Windows, Android and leave Linux just for the kernel itself.

I haven't had to deal with any of that, but I've had Windows straight up refuse to boot multiple times and the only fix I found was to reinstall. I've now had to advise multiple people who couldn't turn on their WiFi in Windows (the switch just did nothing). I also couldn't fix that without a reinstall (not for a lack of trying). My family iMac refuses to import photos from an iPhone into Photos, failing the transfer silently. I have no idea how I'd even go about fixing that besides calling Apple and forcing them to fix it.

No man gets to deal with all of the possible computer problems, thankfully. But in my experience, most Linux problems have been fixable and I managed to fix them, while more closed OSs have left me stumped many times. I no longer believe that a computer can work without problems, so my priority is making sure that when problems appear, I can diagnose them and fix them easily.
