VirtualBox 5.2 Won't Install on Mac OS 10.13 Trying to install VirtualBox 5.2 on a Mac running OSX 10.13. The installation fails with an installer message reading "The installation failed."

I've tried the 2 solutions I've been able to find and neither have worked.

I tried clicking "allow" in the "Security &amp; Privacy" preference panel where the download gets blocked. Each time, I ejected the image before trying again with no luck.

I also tried entering sudo spctl --master-disable in the terminal before trying again, but still no luck.

After the failure, the application icon does still appear in the downloads folder, but I'm supposing this isn't a good installation and I'll run into problems using it? Thoughts?
This worked for me on High Sierra 10.13.4:


System Preferences > Keyboard > Shortcuts > Select 'All Controls'




Then:


System Preferences > Privacy &amp; Security > Press 'Tab' until 'Allow' is selected > Press 'Spacebar'


Note: the Privacy &amp; Security page may need to be unlocked before 'Tab' will work.

Hope this helps!
