Upon starting my virtual machine it stops immediately with an error message:
Fatal error occurred in the virtual machine "Mac OS X"
3D acceleration is not supported in OS X virtual machines, therefore there is no point of assigning more than 64 MB of video memory to OS X virtual machine. This overload may cause virtual machine to crash on some Macs.
To fix this issue please download and install the latest update for Parallels Desktop 9 for Mac by clicking on Parallels Desktop menu and selecting Check for Updates...
If the issue was not fixed after installing the update please quit Parallels Desktop application and start it again.
