macOS unable to open any non-Apple application • Hacker News Board

The computer is completely unresponsive as the OS is blocking all apps from starting. The best part was that the "keyboard" was not found.. in my macbook.

Does anybody now how to disable all hashing on macOS? The best I could do was disable GateKeeper with `sudo spctl --master-disable`.

You can also disable code signing enforcement and amfi by adding the following boot args: cs_enforcement_disable=1 amfi_get_out_of_my_way=1

Thanks, you can also disable library code signing validation too:

`sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true`

Captain Pedantic checking in, should not the title simply be "Macs unable..."? I don't see anything MacBook Pro-specific.

Define “taking down”

Ypu have to send a hash of every program you run.

Unix workflows like to call hundreds of small programs.

If Apple doesn't respond in time, your system halts.

Is it possible that we (the internet) don't understand this properly because by this logic, the apps shouldn't run when there is no internet connection. I don't believe that is the case.

No connection -> Fine Good connection -> Fine Spotty connection -> Problematic. Basically, they didn't include a timeout in their network code.

It's funny how many apps have this problem, you don't realize until you're on a spotty connection. Often disabling/cycling the wifi/network fixes an app freeze.

"If you're now experiencing hangs launching apps on the Mac, I figured out the problem using Little Snitch."

Well, how interesting that Apple's software is going to be bypassing Little Snitch, making it harder to discover and fix this sort of issue.

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: https://mobile.twitter.com/llanga/status/1326989724704268289 > 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,…

Turning off wifi/ internet connection fixes the slow start for me
