Error inserting guest additions CD image?

Post by Exuin »

I'm trying to share a folder between my computer and the VM (macOs big sur). When I try to insert the guest additions CD image it gives me this error:
Unable to insert the virtual optical disk C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso into the machine macOS.



Could not mount the media/drive 'C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Callee: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}
What do I do?

VERR_PDM_MEDIA_LOCKED is a common error and can be web-searched.

However, Mac guest is only allowed if the physical computer is real Mac hardware.
