All VMs crash on macOS 10.12 with NS_ERROR_FAILURE (0x80004005)

[JackMacWindows]

Hello, Whenever I launch any of my VMs on macOS 10.12, the VM crashes immediately with NS_ERROR_FAILURE (0x80004005). The whole error given by VirtualBox:

Failed to open a session for the virtual machine OS X Install Test.

The virtual machine 'OS X Install Test' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005) Component: MachineWrap Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

No VBox.log file is made, but a Crash Reporter log is given, which I have attached. It mentioned "Illegal Instruction: 4" and "BUG IN CLIENT OF LIBDISPATCH: _dispatch_main_queue_callback_4CF called from the wrong thread".

@JackMacWindows: Take a look at the following discussions. There are some workarounds, different but some have reportedly worked:

I tried all of the solutions posted, but none of them fixed the problem. I'm going to try reinstalling VirtualBox again.

Ok, a reinstall fixed the problem. I guess it was just not reinstalled properly.

That's good to know. You updated OSX after you installed VirtualBox?

I guess the ticket can now be closed.
