I'm trying to install HAXM for Android Studio on macOS 10.13. I went to the 'Security & Privacy' panel in order to allow the software to run, but I've run into an issue.
No matter how many times I press 'Allow', nothing seems to happen. The message and button remain… I've even rebooted. It's still there.
Managed to solve it.
Eject the VirtualBox image from: Finder > Devices
Now allow the exception in: System Preferences > Security & Privacy
Finally but not least click Allow button so that way the developer with the name "Oracle America, Inc" will be accepted and the installer using that certificate will run just fine (basically this installer is signed using "Oracle America, Inc" certificate so we are required to enable it use on our machine first)
Then try to install from the .dmg again so that it remounts the device.
Now its working fine for me.
I had these same issues installing VirtualBox 5.2 on an employees Mac running 10.13, via remote desktop. After trying all the things you've mentioned I kept googling, eventually finding this thread saying it's a screensharing issue.
There is a report that you cannot allow kext if you are using Screen Sharing.
I use magic perf to intercept various touchpad actions. [...] If you have this problem try to disable any apps that my capture and forward clicks.
Apple are disabling the "Allow" button if it's pressed by anyone BUT the Mac touchpad, directly.
So, if you're also attempting this via some sort of indirect method, or are using something like Magic Perf or Steermouse, disable those and make sure the click on "Allow" is as direct as possible.
Hope this helps someone out there.

This is a new feature in macOS High Sierra that blocks kernel extensions from 3rd-party developers until manually allowed via the Security & Privacy preferences pane. Note this is different from Gatekeeper — this blocks signed kexts until you allow them, and all unsigned kexts are blocked unless System Integrity Protection is disabled. Gatekeeper blocks unsigned apps from running until you allow them. Apple has some further details in TN2459: User-Approved Kernel Extension Loading.
According to reports such as this issue thread for Karabiner, programs that might be intercepting or simulating mouse clicks such as MagicPrefs or VNC could be at fault. If you can temporarily disable those programs, and be in front of the machine rather than connected remotely via Screen Sharing or similar, it will work.
As a more complex workaround, you can disable System Integrity Protection for kexts with
csrutil enable --without kext, then reboot to the regular OS and ensure the Android emulator is working, then (optionally but recommended) reboot to Recovery Mode again and re-enable SIP withcsrutil enable. This will automatically add all installed signed 3rd-party kexts to the whitelist.
