Hi!
I'm trying to install Paralles 13 (trial version) on a fresh installed iMac with macOS 10.13.1 (17B48) and all available updates.
It is not possible to allow the installation of the paralles system extensions as described here: http://kb.parallels.com/en/124244
I can click the button "allow", but nothing happen then.
What is the problem?
 
I have the same problems that SebastianA2.
I also have High Sierra 10.13.1
I try to install. (install ParallelsDesktop 13.1.1)
Get message that I have to press Allow.
Open Preferens. Press Allow.
Nothing at all happens.

What to do... :-(
 
Can you please post output of this terminal command?
sudo kextutil /Applications/Parallels\ Desktop.app/Contents/Library/Extensions/10.9/prl_hypervisor.kext
 
After I run this command I only get prompted to put in password.
Then I get the prompt back again. So there is no output of this terminal command!
 
I get this:
Kext rejected due to system policy: <OSKext 0x7fd99d900180 [0x7fff98c75570]> { URL = "file:///Library/StagedExtensions/Applications/Parallels%20Desktop.app/Contents/Library/Extensions/10.9/prl_hypervisor.kext/", ID = "com.parallels.kext.hypervisor" }

Diagnostics for /Applications/Parallels Desktop.app/Contents/Library/Extensions/10.9/prl_hypervisor.kext:​
Seems like Parallels hasn't updated its Kext file.
 
I was able to fix it using the guidance in your TeamID knowledgebase article by restarting in Recovery Mode and then opening Terminal and run
spctl kext-consent add 4C6364ACXT​
After restart all was as it should be. You might want to fix this for other users though.
