VirtualBox 6.0.8 does not install on Mac OS 10.14.5 -> duplicate of #18645

[Kevin L Mitchell]

Installation just fails with some message about the software not being compatible with the version of Mac OS. An existing 6.0.6 installation seems to function fine (though I had to re-install it after 6.0.8 failed to install). Looks like some driver could not be installed.

I tried sudo

 kextcache --clear-staging

It cleared the /Library/StagedExtensions folder, but it still failed.

Here's some output from kextutil

Yeah, #18645 didn't come up on my attempts to search prior to opening a new report. Mods may close this as a duplicate of #18645.
