Installation succeed But can't start the simulator
At first I downloaded a genymotion, but it informed me to download a virtualbox. Then I clicked the link and download a 5.2.22 version. It was installed successfully without any failing notification. I continue to use genymotion and choose a android 8.0 simulator. But it failed to launch. And it said like this:

Unable to start the virtual device.
VirtualBox cannot start the virtual device.
To find out the cause of the problem, start the virtual device from VirtualBox.
For more information, check the log files. Please refer to: http://www.genymotion.com/faq/logs

So I turned to open virtualbox. But when I click the virtualbox icon, nothing happen. The virtualbox's UI did not display!
Then I uninstall my virtualbox 5.2.22 using the script in the official dmg, and downloaded a virtualbox 6 rc1, then I installed it. Succeeded again but still with no notification or other instruction to approve some third kext blabla. THis time I open virtualbox successfully, and click the start button. Then it told me:

The virtual machine 'Android8.0' has terminated unexpectedly during startup with exit code 1 (0x1).
NS_ERROR_FAILURE (0x80004005)
MachineWrap: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}

So I find some log file only to find that all the kext loaded successfully.

1. Genymotion is a program that relies on VirtualBox, but modifies its configuration files in unknown ways to us, and with unknown consequences. It is not supported on these VirtualBox user forums, they have their own Genymotion support channels. If you are having this problem with a standalone version of VirtualBox (after a complete uninstallation of Genymotion), then we can continue this discussion.
2. Android is not a supported guest OS. Can you try with something more supported as a test? Like a Linux Mint live DVD?
3. The kernel extensions seem to be up and running, so I don't think it's the known 10.13/14 issue where you need to get permission from the Security in the System Settings.
4. This is not an "OSX Guests" issue, but an "OSX Hosts" issue. Moving accordingly...
