Install Virtual box on mac OS +10.3 with security kernel can failed. After you have this message :

Kernel driver not installed (rc=-1908)

because you have to add editor Oracle in the list of security kext.

If you have chance, you can see the ask for authorisation in Preference -> "Security and Privacy".

But it was not my case. I want to share the solution, because it was a really pain for me: Add Oracle editor in this authorization list.

Restart your mac in Recovery mode (cmd + R)

Then open a Terminal and enter : spctl kext-consent add VB5E2TV963

Restart your mac.

VB5E2TV963 is the code for oracle.

Apple states in tech note tn2459 that it only prompts once and that the text in the system preferences is only visible for 30 minutes.

I did the following to view the allow button again:

• close the system preferences
• install virtual box again (it states that it failed)
• open system preferences - security: and the allow button appeared again
• Virtual Box worked for me
