Fix: Kernel Driver Not Installed (rc=-1908) VirtualBox Mac
When you try to launch a virtual machine in Oracle VirtualBox, you receive successive error messages.
Kernel driver not installed (rc-1908)
Make sure the kernel module has been loaded successfully.
- The support driver is not installed. On linux, open returned ENOENT
You may also receive this error message:
The virtual machine “” has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code: NS_ERROR_FAILURE (0x80004005)
If you recently installed Oracle VirtualBox, restart your computer to ensure the VirtualBox drivers loaded correctly.
All else, it is possible Mac OS is blocking the Oracle VirtualBox kernel extension. Follow the steps below.
- Go to System Preferences -> Security & Privacy and choose Allow from the bottom of the screen. (If you do not see this, then Mac OS is not blocking the Oracle VirtualBox kernel driver extension).
- Search for an extension named Oracle and check the box next to it to allow it.
- Restart your Mac.
I think that "Allow..." option appears only for a while after the error. You may need to try (and fail) again and then go to the "Privacy and Security" again. You may even need to uninstall Virtualbox and reinstall it.
I do not know where to enter your bullet point 2?
Nevertheless "System software was blocked from loading" is not shown. Where would it be supposed to be displayed. How can I determine where it is displayed or if it is displayed at all?
probably I am running an updated version of macos.
What os version is the article relating to?
" (If you do not see this, then Mac OS is not blocking the Oracle VirtualBox kernel driver extension)."
What should you do then? I've tried adding kext manually also.
