I'm trying to install a VirtualBox dmg file on macOS Sierra. It's from Oracle, a trusted source. However, when I click on it, nothing happens. Nothing happens even when I Ctrl + click and then select Open. Please help.
Double click on .dmg file and click on open .

Try downloading it again.
You can try opening it in another admin user account, but it does appear to be a faulty download.
I did that, however it doesn't work.
