Copy/Paste - From Mac to Virtual box

You can use the help menu in VirtualBox (and other applications) to very easily to find what you need:

I prefer bidirectional setting so I can copy and paste back and forth between systems

I'm using a Windows VM on a Mac OS host. I had to install the Guest Additions onto the actual VM so that it knows how to communicate with the host machine. Here's what I did:

• launch the Windows 10 VM
• In the top menu go to Device -> Insert Guest Additions CD image
• On the Windows VM go to Explorer, then look for the drive that represents the newly "inserted" CD
• Once there, run VBoxWindowsAdditions.exe as administrator and install
• Enable Clipboard and Drag&Drop under either VM settings or the Devices menu

This article has helped me understand how it works.

Copy from MAC with ⌘ + C and Paste to VirtualBox with ctrl + ⇧ + V

Vice versa ctrl + ⇧ + C in VirtualBox and ⌘ + V on MAC would also work! ;)

Check if the "Shared Clipboard" feature is disabled. It should be somewhere around Settings > General > Advanced. You can set it to bidirectional or any other setting you need.
