MAC with BIG SUR — Kernel driver not installed (rc=-1908)
Make sure the kernel module has been loaded successfully.
where the error is:
suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.
Download and install the latest VirtualBox 6.1.18 or higher. And then follow the below steps to resolve.
Step 1 – run:
sudo kextload -b org.virtualbox.kext.VBoxDrv
Step 2: Go into System Preferences->Security & Privacy
Step 3: Unlock the security center
Step 4: Approve the software by Oracle
sudo kextload -b org.virtualbox.kext.VBoxNetFlt sudo kextload -b org.virtualbox.kext.VBoxNetAdp sudo kextload -b org.virtualbox.kext.VBoxUSB
Step 6: Reboot
Registering the .kext directly via terminal solved this issue for me.
sudo kmutil load -p '/library/Application Support/VirtualBox/VBoxDrv.kext'
There should be a prompt in System Preferences to allow the kernel, which will require a reboot.
Reboot and run command
cd ˜/Homestead && vagrant up
Big Sur disables the VirtualBox kernel extensions as part of the installation process. You can verify this by running:
kextstat | grep -v com.apple
If the kernel extensions are installed, you will see something like this:
Executing: /usr/bin/kmutil showloaded No variant specified, falling back to release Index Refs Address Size Wired Name (Version) UUID <Linked Against> 184 3 0xffffff7fa232d000 0xb2000 0xb2000 org.virtualbox.kext.VBoxDrv (6.1.18) 9C1C33DF-8061-30A2-9266-C9284816A6A2 <8 6 5 3 1> 187 0 0xffffff7fa240a000 0x5000 0x5000 org.virtualbox.kext.VBoxUSB (6.1.18) 51E577B4-43B6-359F-B817-9C63A69E7943 <186 184 62 8 6 5 3 1> 188 0 0xffffff7fa2405000 0x4000 0x4000 org.virtualbox.kext.VBoxNetFlt (6.1.18) 96E530DE-E34D-3447-89A5-FCF6646AE47E <184 8 6 5 3 1> 189 0 0xffffff7fa23ff000 0x2000 0x2000 org.virtualbox.kext.VBoxNetAdp (6.1.18) 63EFABA5-3341-3BEB-B47A-AAFCDD7312A5 <184 6 5 1>
If you don’t see the extensions loaded, the easier fix is to delete your current VirtualBox app, download and install the lastest version and then go the Security & Privacy System Preferences Pane. You should see a message that some applications require a restart to work correctly.
Restart your Mac and VirtualBox should now work. You can re-run the kexstat command just to be sure the extensions were loaded.
Here is how I solved the issue on MAC with MONTEREY
Update 09 december 2021 : installing the latest version (
VirtualBox-6.1.30-148432-OSX.dmg when updating this post) completely solve the issue on my machine
Initial post :
- Download the latest installer of VirtualBox (
VirtualBox-6.1.28-147628-OSX.dmgwhen writing this post)
- Launch the installer
- Double click on the file
VirtualBox_Uninstall.toolin order to uninstall VirtualBox
- Reinstall VirtualBox
Solution worked for Big Sur (no need to delete anything):
- Update VirtualBox
- Install VirtualBox Extension Pack https://www.virtualbox.org/wiki/Downloads
- Settings -> Security -> General settings -> Unlock settings
- On “General settings” form turn allow application usage checkbox from “App Store and others…” to “App Store” and back to “App Store and others…” (to make sure Mac recognised the changes made before on steps 1-2)
- Go to “Additional settings” (“General settings” form button right after application usage checkbox), system will show Applications changes made before (steps 1-2), push “Ok” and system will ask for reboot
- After reboot VirtualBox will work
I also got the same error while trying to run Windows 10 on macOS Big Sur 11.6, but I was easily able to fix the issue by navigating to System Preferences > Security & Privacy. There, under allow apps downloaded from section I found something like Oracle wants to install additional updates, and I gave permission. My Win 10 VM started to work. I hope this help.
On MacOS Monterey 12.4, I just installed the latest version and opened VirtualBox (version 6.1.34 r150636 (Qt5.6.3)). Then:
Step 1: Went into System Preferences->Security & Privacy.
Step 2: Unlocked the security center.
Step 3: Approved the software by Oracle.
I haven’t uninstalled my old virtualBox or restarted the machine or typed any code.
after googling for few days and no solution worked for me on macos
I run the below commands
sudo kextload -b org.virtualbox.kext.VBoxDrv sudo kextload -b org.virtualbox.kext.VBoxNetFlt sudo kextload -b org.virtualbox.kext.VBoxNetAdp sudo kextload -b org.virtualbox.kext.VBoxUSB
go to “https://www.virtualbox.org/wiki/Downloads”
and download “VirtualBox 6.1.30 Oracle VM VirtualBox Extension Pack” all platform
then open your virutalbox preferences –> choose extension –> and add the extension you just downloaded and eveything will be ok
Another restart of the system solved my problem as I was already at the most current version of virtualbox. My macOS upgrade was from Big Sur 11.6.1 to 11.6.4.
None of the methods here worked for me, the option to approve the driver in System Preferences / Security & Privacy never appeared.
The only way I could get to approve the extension was rebooting in recovery mode, and then giving consent to the Oracle Developr ID running in the Terminal the following command:
spctl kext-consent add VB5E2TV963
Then after a reboot, I could approve the driver and VirtualBox works just fine. Tested in Monterey 12.3.1

I started getting this issue when my Mac updated from Big Sur to Monterey. I just downloaded and installed the latest version of VirtualBox on my Mac and it started working like earlier.
I couldn’t make the option to allow the kext appear in System Preferences either. Rebooting, reinstalling VBox and running
sudo kextload -b org.virtualbox.kext.VBoxDrv didn’t help.
I discovered another cause: in my case, I had to enable WiFi for internet access and also allow
syspolicyd to contact
api.apple-cloudkit.com in Little Snitch (it is allowed by default, but I’d disabled that rule). Then running
sudo kextload -b org.virtualbox.kext.VBoxDrv forced
syspolicyd to verify the signature (or whatever my data it may be uploading) — the option appeared in Security & Privacy and I could allow it finally.
So if anyone has such an issue, try verifying that
syspolicyd can contact
