Installing VirtualBox On a Mac

When Installing Virtual Box on recent versions of MacOS, two problems arise:

  1. The installation fails unless the you grant it privilege.

  2. Once the installation completes, when you launch Virtual Box, the application fails because
     additional kernel modules are needed.

We discovered the following steps on the web, and found that they work.  Here's what you do.

To Install Virtual Box

1. From https://download.virtualbox.org/virtualbox/6.1.34/ download

	VirtualBox-6.1.34-150636-OSX.dmg

2. Prepare to reboot your computer (i.e., save files and close applications)

3. Get ready to grant privilege to the installer:

   Open System Preferences -> Security & Privacy, and click the "General" tab.  Leave it open on
   the Desktop for Step 5.

4. Open the dmg file you installed in Step 1 and double click the VirtualBox.pkg icon.

5. grant privilege during installation

   On some systems. during the installation, you will reach a step where kernel changes are
   required.  The installer will ask if you want to open System Preferences, but it is already
   open.  A reques tfrom from Oracle Inc. will appear in the Security & Privacy window you
   opened in Step 2.  Click the lock to allow changes, enter your password, and then click
   "Allow" on the request from Oracle.  You will receive a notification that a reboot is
   required for the changes to take effect.

   On other systems, the installer will complete the kernel changes, and you may not see the
   notification about rebooting.

   IMPORTAN: whether or not you receive the reboot notification, a reboot is requried, so
   restart your computer.  Do it immediately, even if the installer has not exited --
   rebooting later does't seem to work.

   Once the system reboots, eject the installer and move the dmg file to the trash.

6. Add additional kernel modules

   Although it may appear that Virtual Box has been installed, it may not be ready to run.
   Try it, and if an error message appears. you will need to install additional modules.
   Launch a Terminal window and enter the following command:

                sudo kextload -b org.virtualbox.kext.VBoxDrv
		(Enter your password when prompted.)

    Then enter following commands:


                sudo kextload -b org.virtualbox.kext.VBoxNetFlt
                sudo kextload -b org.virtualbox.kext.VBoxNetAdp
                sudo kextload -b org.virtualbox.kext.VBoxUSB

Now the installation is finished.  You can launch VirtualBox and import the two Xinu appliances.
