Users who are running earlier versions, like Yosemite, El Capitan, or Sierra might want to update their operating systems to the latest available one. MacOS High Sierra is an operating system for Macintosh computers which are developed by Apple Inc. Other people have had success triggering the button click with AppleScript, but that did not work for me.To repair damaged system, you have to purchase the licensed version of Mac Washing Machine X9 Mac Washing Machine X9. Following dansanduleac's advice in this thread I was able to finally click the "Allow" button using the keyboard. However subsequently experiencing the same unresponsive "Allow" button when trying to install a different kext made me realize this issue was not limited to VirtualBox. I was able to install VirtualBox after disabling SIP (restart from Recovery partition and run csrutil disable at the Terminal) and it remained functional after re-enabling SIP. VirtualBox appeared to be installed but would fail when trying to boot a virtual machine, saying the kext was not loaded. So the VirtualBox kext was never allowed and repeated installation attempts would never report success, even after rebooting. In my case I believe the small keyboard app "High Sierra Media Keys" (which has no mouse-related functionality) was causing OS X High Sierra to ignore my mouse clicks on the "Allow" button.
#MAC OS SIERRA INSTALL PROBLEMS SOFTWARE#
High Sierra seems very paranoid about only accepting mouse clicks from the local computer and will reject mouse clicks over VNC / Remote Desktop, and ALSO for locally attached mice/keyboards if any 3rd party mouse/keyboard/touchpad software is installed. The VirtualBox installation may repeatedly fail if clicking the "Allow" button in System Preferences appears to have no effect. TL DR - remote access or ANY 3rd party mouse or keyboard software may trigger High Sierra to ignore your mouse click on the "Allow" button. I resorted to disabling System Integrity Protection to get past this installation failure, but I later figured out what was causing my VirtualBox installation to repeatedly fail.

Note: If the Allow button is there but clicking it does nothing, use the Tab key to focus on it and the Space key to press (you will need Full Keyboard Access enabled for this method to work).

Note: If the Allow button does not show up, run sudo kextcache -system-caches This effectively breaks our fully automated installation process on macOS, since the user now has to perform a manual approval and then restart the installation (reboot and rerun the installation in some cases) This issue affects anyone installing VirtualBox for the first time on a fresh macOS High Sierra 10.13. Apps or installers that treat a KEXT load failure as a hard error will need to be changed to handle this new case.Īpproval is automatically granted to third-party KEXTs that were already present when upgrading to macOS High Sierra.

When a request is made to load a KEXT that the user has not yet approved, the load request is denied. MacOS High Sierra 10.13 introduces a new feature that requires user approval before loading newly-installed third-party kernel extensions (KEXTs).
