If you’re getting an error about Virtualbox Enable Auto Capture
The Virtual Machine reports that the guest OS supports mouse pointer integration. This means that you do not need to capture the mouse pointer to be able to use it in your guest OS — all mouse actions you perform when the mouse pointer is over the Virtual Machine’s display are directly sent to the guest OS. If the mouse is currently captured, it will be automatically uncaptured.
The mouse icon on the status bar will look like to inform you that mouse pointer integration is supported by the guest OS and is currently turned on.
Note: Some applications may behave incorrectly in mouse pointer integration mode. You can always disable it for the current session (and enable it again) by selecting the corresponding action from the menu bar.
Enabling Virtualbox Auto Capture
