Re: Installation fails on 10.13.x, 10.14.x (rc=-1908)

Hi,
I also need to add to this thread...
I updated VirtualBox from 6.1.8 to 6.1.16 on my Mac running Mojave and the installer failed with "The installation failed. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."
I remebered this to be common and usually you just need to allow the kernel extensions in "Preferences > Security & Privacy > General". But nothing was there, also I would expect that on a fresh install not an update. VirtualBox ran just fine before the update!
I checked the loaded kexts, but nothing:
I did some googling and found several threads on different forums and tried some of the suggestions.
I ran
and tried again. No change. I ran the uninstall.tool and installed again. Did that again but rebooted in-between.
Found this script and tried to load/unload the kexts that way and get them to appear in Preferences:
I then went to rescue mode and ran
I got the ID from
and re-tried all of the above. Never did I see any prompt to allow the extension in Preferences.
Compare (the consent-list was empty before I did that):
As a last resort I then re-entered rescue mode and entered
and rebooted. Without any further intervention the kexts were loaded and VirtualBox worked.
But when I enable csrutil again I am back to where I came from.
Any more ideas what I could do to get the extensions approved? Any more logs I could provide?
Thanks!
EDIT: So I have actually been able to fix this right now. I cannot fully recall which error
produced, but it had something to do with a staging error and a temporary directory. I have elaborated on this more in my post below.
In the end I could fix it by running the following from the rescue environment after unlocking "Macintosh HD"
Afterwards rebooted and verified:
Extensions can now be loaded again!
