I have tried to install VirtualBox 5.1.28 to macOS high sierra but it fails every time with the following screen:
After some looking around I found this thread and I did indeed see that it was blocking VirtualBox from installing.
After clicking allow and then trying to run the VirtualBox installer again it just fails again with the same generic error message and the same Security warning reappears in the 'Security and Privacy' settings.
I tried to also run the pkg install from the terminal to see if I could get more information about why its failing but it doesnt help.
![]()
The VirtualBox application does appear to install and it can be launched however nothing functions.
Does anyone have any ideas how to solve this?

The answer at the following link worked for me. It required running the script provided by
dstroot , approving the kext in Security & Privacy and then installing with brew cask reinstall --force virtualbox --verbose --debug . https://github.com/caskroom/homebrew-cask/issues/39369

For those still struggling with this issue:
IF YOU ARE CONNECTING VIA REMOTE DESKTOP OR SCREEN SHARING or have any other mouse emulation running: It is not possible to actually click the
Allow button in this mode!!
So do the following:
Virtualbox Error Not Registered To Open
Now the button is actually clicked, and you can allow 'Oracle America, Inc.' to install. You might be prompted for a reboot. Then run the installer again and everything should work as expected!

If the GUI solution does not work, reboot in Recovery mode and enter
spctl kext-consent add VB5E2TV963 , then reboot in normal mode and install should be ok.

For some reason when I clicked 'allow' it felt as if the button 'did nothing' but then when I tried it a third time the button 'took' (after which point it always worked). Weird.
More ideas:
reboot into safe mode, try the allow button there
command line:
sudo spctl --master-disable
This is a community wiki feel free to add some more ideas here.

I saw a quick note in one of the messages here or in another thread and it was the critical piece I was missing.
When I had the Security & Privacy dialog open, the Apply button visible and clicking on the button and there was no apparent action. The prompt still remained. I needed to WAIT longer before trying the Apply. I found I waited 20 minutes until the button actually worked (the prompt went away).

Virtualbox Error Not Registered Windows 10
Hi,
I'm trying to install OSX in VirtualBox following the next tutorial: https://medium.com/@twister.mr/installing-macos-to-virtualbox-1fcc5cf22801
I have also follow similar tutorials that ended with the same result.
When running VBoxManage modifyvm MacOS --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbf
I get the following error: VBoxManage.exe: error: Could not find a registered machine named 'MacOS' VBoxManage.exe: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBoxWrap, interface IVirtualBox, callee IUnknown VBoxManage.exe: error: Context: 'FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())' at line 522 of file VBoxManageModifyVM.cpp
I've tried modifying the command in notepad++ (basically 'delete' and re-add the spaces between the name MacOS) as well as using 'MacOS' and 'MacOS' with no success.
Any ideas on why this is happening?
