New release of Virtualbox VM 6.1.18 crashes on Mac OS Bigsur host

Post by stazeb »

When I try to open a VM 6.1.18 (does not matter if Windows or Linux), the error occur.
Kernel driver not installed (rc=-1908)
Make sure the kernel module has been loaded successfully.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908)

Happens with the test build VirtualBox-6.1.18-142142 on iMac Retina 5K late 2014 and macOS Big Sur version 11.1.
I have tried suggestion to completely uninstall VB 6.1.16 using dmg file then in terminal run [csrutil clear] without success.

Read the other thread that discusses this in detail

However even when I followed the instructions detailed, after the restart and VM crash again, I need to verify once more the System Security and restarted Virtualbox

Apple released Big Sur 11.2.3 update just last night, in Australia.

Installed on my iMac and after the reboot, my Virtual Box install Version 6.1.18 r142142 (Qt5.6.3) started working again.

I too had the infamous Kernel driver not installed (rc=-1908)... etc. error

But the update for me at least seems to have fixed it. No other attempted mods by me.

Hope this helps the community.
