[vbox-dev] Turning on Virtual Disk (VD group) debug logs on VBox

[Alexander Eichner]

Hi Quaizar,

you need a special debug build to be able to enable logging.
There are build instructions for OS X on our website: https://www.virtualbox.org/wiki/Mac%20OS%20X%20build%20instructions

Regards,
Alexander Eichner
