I'm running Mac OS Mavericks under Virtual Box 6.0 and can't get it to run full screen or get access to my other files and folders. All the tutorials on Youtube are for Windows and show typing commands in command prompt so this does not work for Linux. Also I can't get access to my systems files folders even after I try adding a folder via the Shared Folders option but after that I can't find that folder anywhere in finder or when I click on the Macintosh Hard Drive Icon.
There is no setting under Displays in the Virtual Box setting for screen resolution, just how much video memory to assign the the Virtual Machine. This is in version 6.0 that I manually install from the Virtualbox.org Website because the previous version of Virtual Box won't even run Mavericks.
