We’re going to have to tell our Mac to allow an exception for this one time (it will not change the setting permanently).

However, the download is safe and can be trusted. This is simply because the file did not come from the Apple App Store. When you click on the “VirtualBox_Uninstall.tool” you may see the message above. We want to select the VirtualBox_Uninstall.tool in the lower right-hand corner of the screen to begin uninstalling the app from our Mac. Step 4: we will then be greeted with this window which has a couple of options in it. There will then be a window showing that the dmg is verifying itself and it will then automatically launch.

Step 3: double-click the VirtualBox dmg file to launch the app. Step 2: click on the “Downloads” folder which is located under “Favorites”. Step 1: once the app has been downloaded, we want to launch Finder. You can download the app by clicking here which downloads the app from the MacUpdate website onto your Mac. If you’re unable to uninstall VirtualBox double-check that none of the steps below were missed as that could be the issue. We’re going to download the dmg to get access to the uninstaller tool. Using this method is more efficient than dragging the program to your trash as it will ensure that all files associated with VirtualBox are deleted from our Mac. Lucky for us, VirtualBox has an uninstaller tool that is built into the dmg (disk image) of the app that we’re going to use. While you can do it that way, that won’t provide you with a clean uninstall of the app. Uninstalling VirtualBox requires a couple of extra steps rather than dragging the app to your trash.
