Problems encountered when installing VirtualBox with MacOS brew cask

Problem 1: Cask 'virtualbox' is already installed.

If virtualbox is not installed through Homebrew, when you use brew cask install virtualbox to install virtualbox, you will be prompted:

Warning: Cask &#39;virtualbox&#39; is already installed.

Copy after login

Then you need to reinstall virtualbox, command:

brew cask reinstall virtualbox

Copy after login

If this is not the case , your virtualbox happens to be running, and it will prompt:

Failed to unload org.virtualbox.kext.VBoxDrv - (libkern/kext) kext is in use or retained (cannot unload).

Copy after login

Then, you need to pull the log online and find:

Warning! Found the following active VirtualBox processes:

Copy after login

These are the list of running virtual hosts, the first column of which is their ID, use the kill command to shut down the service, such as:

kill 234

Copy after login

Then reinstall:

brew cask reinstall virtualbox

Copy after login

Question 2: Error: Failure while executing;

The last step of installing virtualbox will ask you to enter the computer login password. However, after you enter the password, you may still be prompted with an error. This is because of permission issues. The main information is as follows:
