[Resolved] VBoxDrv.kext failed to load

Ive read all the posts but still cant resolve this issue. during the installation I have gone to security & Privacy but there is no option to "Allow Oracle" that appears either before during or after installation.
Im running Mac OS High Sierra, its a fairly new machine and im a bit of a novice so bear with me.
I downloaded virtual box and attempted to install. but I get the Installation failed message. during the installation Ive looked in the security & Preferences but where people have referred to a message asking me to allow the installation from Oracle There is nothing there. No I have had this message for another piece of software I installed but for some reason it does not appear during the installation of VirtualBox.
I have attached my installation log.
Any help would be appreciated.
Thanks

@Ryan.Watson
It seems that you have a permissions problem with your setup:
Feb 12 06:03:42 DMI27s-MBP installd[496]: ./postflight: /Library/Application
Support/VirtualBox/VBoxDrv.kext failed to load - (libkern/kext) authentication
failure (file ownership/permissions); check the system/kernel logs for errors or
try kextutil(8).
Why exactly is that? Have you willingly modified some system permissions? Anything system-wide-modifying installed? Post the output of the command:
Code: Select all
ls -laed@ \
/ \
/Applications \
/Applications/VirtualBox.app \
/Applications/VirtualBox.app/Contents/MacOS/VirtualBox \
/Applications/VirtualBox.app/Contents/MacOS/VirtualBoxVM \
/Applications/VirtualBox.app/Contents/MacOS/VBoxRT.dylib \
/Library/Application\ Support/VirtualBox \
/private \
/private/etc \
/private/etc/sudoers \
/private/tmp
PS. I've removed your duplicate post. According to the forum rules,

I honestly don't know why that it, I may have done something inadvertently but Im a bit of a novice. Below is the result of the command

The permissions look fine. I will need you to list the output of a couple more commands:
Code: Select all
ls -laed@ \
/Library \
/Library/Application\ Support \
/Library/Application\ Support/VirtualBox
ls -ale@ /Library/Application\ Support/VirtualBox
ls -ale@ /private/tmp
Something is definitely not right with the permissions. The question is "what". I'd hate to force you to re-install OSX just because of a small glitch...

Thanks for this. I haven't really set much up on my device so I can do a re-install if necessary.
Thanks

Again, everything looks appropriate, permissions set as they should. I don't know what might be wrong here. Sorry about that...

In Terminal.app Can you try running the following:
sudo kextutil -v -t /Library/Application\ Support/VirtualBox/VBoxDrv.kext
If it reports anything we don't already know then post it here.

Well, I'm not sure we helped at all, if you had to reinstall at the end to get things going. It would have been a good learning experience if we had gotten to the bottom of the failure. Oh, well...
Marking as [Resolved].
