You have to SUDO xattr -d com.apple.quarantine <app>

Thanks for the tremendous support. Since it's a learning project - https://github.com/johnothwolo/noah and nothing serious I'll just wait for Apple to iron out Big Sur and its Frameworks.

My apologies for replying a week later, I've been busy. Which one are you calling? And what error result do you get back? I get error -85377023 with hv&#92;&#95;vm&#92;&#95;create, and I can confirm I'm using the right header (hv.h not hv_vm.h), which is supposed to be the x86 flavor. And can the admin edit the title to Hypervisor Framework?

There is no HypervisorKit, just Hypervisor framework. Yeah my bad with "Kit". I confuse the naming scheme with AppKit/HomeKit/WatchKit. Will the documentation be completed, because it looks like there are a bunch of MSR and register functions missing. And despite requiring permission for the entitlements, is that the reason hvvmcreate failed? Because I didn't add entitlements the first time? Because this project isn't sandboxed and has hardened runtime disabled.

100% agree. Let's hope they fix it.
