I am running a Mac OS X Server as the guest and have configured Screen Sharing through the system preferences. Each time I try to access the VM remotely via VNC, it crashes almost immediately with the following message: ""A critical error has occurred while running the virtual machine and the machine execution has been stopped"". This has happened with a different Mac OS X version as well, and occurs regardless of what type of VNC client I use. I tried modifying the VM's parameters like CPU count, RAM size, video memory, 2D/3D acceleration and so on, but nothing has helped." defect closed guest control VirtualBox 4.2.0 obsolete VNC crash OSX Server Mac OS X
