解決MacOS VirtualBox: Error -610 in supR3HardenedMainInitRuntime!

最近項目轉向 Kubernates, 因而想在本地安裝使用 minikube.
但不知是由於什麼時候升級了 MacOS (10.13.3) 仍是升級了VirtualBox, VirtualBox就是沒法正常啓動, 老是顯示錯誤:

VirtualBox: Error -610 in supR3HardenedMainInitRuntime!
VirtualBox: dlopen("/Applications/VirtualBox.app/Contents/MacOS/VBoxRT.dylib",) failed: <NULL>

VirtualBox: Tip! It may help to reinstall VirtualBox.

來來回回卸載安裝不一樣版本也毫無做用...
嘗試使用 brew cask install virtualbox 也能成功, 可是仍是同樣的錯誤, 也沒有輸出任何有用的信息. 非常鬱悶..

可是 brew search virtualbox 的結果裏邊還有一個
caskroom/cask/virtualbox-extension-pack
因而抱着試試看的態度
brew cask install virtualbox-extension-pack

沒想到此次居然有不一樣!

連忙查看/Applications的權限, 不知道何時改爲了 xxx:staff, 趕緊
sudo chown root:wheel /Applications

再次brew cask install virtualbox-extension-pack

?  virtualbox-extension-pack was successfully installed!

成功的預感!
再次啓動 VirtualBox, 久違的界面終於回來了!

minikube start 也能夠成功, 終於能安心學習 K8S 了, 去了一塊心病 :)
