Unable to run Virtualbox after updating to macOS Mojave

I had a problem with my location service in my macOS Mojave, so I decided to reset and successfully reset my macbook, but here is where problems begin. I was unable to install Oracle Virtualbox. I also tried entering into security and privacy and to allow the system extension, but it does not show any options to allow them. I have reset my mac several times, but no use. The location service issue is also not solved yet, that is a different discussion but. I tried reseting my mac to older version of OS X (El Captian), virtualbox worked flawlessly, now I am in macOS Mojave. It is not working. Kindly help me out.

MacBook Air 13", macOS 10.14

The installation failed, but still it allowed me to open the application. When I tried to start my virtual machine, it shows error. Usually it is required to allow the extension in security and privacy section in preference to successfully install Virtualbox. This time it doesn't show the option to allow access in the security and privacy section.

I was reading your post on my iPhone where it is not easy for me to discern the pictures.

I had not realized that you DID install VirtualBox - it is clearly running on your screenshot.

You seem not to be able to successfully run a particular virtual machine inside it.

Apparently, some system extension is being blocked for being "incompatible" with the present system, rather than for security reasons. That may be why it does not show in System Preferences on your screenshot.

I suggest you run Etrecheck and post your report here. There may be other software conflicts that are impacting this, and the report often sheds light on these problems. Use the "additional text" button below the message area and paste the report into it.

When I follow the VB forum steps exactly, the spctl command returns no error, but on reboot, VB6.0.8 still blows up with dialogs that it could not load a kernel driver. Wasn't expecting that per previous input on this subject.

[Update: never mind ... saw a 5 in the code as an S, so expect that was the issue. - /viking]

I can neither confirm nor deny the "fix" for 6.0.8. I've used VB since 2009 and the latest problem installing 6.0.8 before a fix was published and the poor Mac guest support finally made me give up on it for good.

After I applied more squint to that VB developer code, it all works now. 🤓

Although the guest extensions for macOS are a work in progress, that might take years, so I simply do not use VB for macOS. Parallels appears to run my El Capitan installation well. Still using the v1.3.3 Desktop lite to avoid having to pay Corel a subscription fee for v1.4.0+.

Something I have wanted to do is install VMware's free vSphere hardware VM and run a bunch of OS X/macOS guests from that. Small problem, don't have the hardware here to do that.

What version of VirtualBox? It seems that you are trying to install a version that is too old. Download the most recent version from the application site.

It is the latest version (6.0.8) downloaded from the Official Oracle Virtualbox website. I have also tried Virtualbox 5.2, it shows the same error message.
