Allow button not working in system preferences I am trying to install some software, (at this particular moment I want to install VirtualBox, although this issue has happened with other software), and I have to click "Allow" in System Preferences, in the Security &amp; Privacy -> General window. When I click on it, nothing happens, and the button and message stays there.

I looked online, and all of the solutions say that there is some kind of program running that captures/forwards mouse clicks and such, and thus I am not "directly" clicking on the Allow button.

The problem is that I don't know of any programs that I'm running that do this.

I am on a Macbook Pro 13 inch 2016 with touchbar, running macOS High Sierra


I am not connected remotely
I have tried restarting my computer
I have tried running the installer through terminal, with and without the sudo command
I have tried right-clicking and clicking on "open" on the .pkg file
I have tried unlocking the system preferences page before clicking "Allow"
I tried re-downloading the .pkg file
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.

*Note: After open Security &amp; Privacy and selecting General tab you should push tab key to select allow button after that push space bar key!

Hope this helps!
