Oracle VM VirtualBox 4.3.10 is primarily a maintenance release fixing bugs but also adds some new (experimental) features. Mac OS X users can now experience native full screen support for Mountain Lion and Mavericks. Simply press the "Host key" + "F" to toggle this on or off, or go the View menu to "Switch to Fullscreen".
An additional (experimental) new feature is the keyboard indicators (HID LEDs) synchronization for Mac OS X hosts. This feature makes the host keyboard lights match those of the virtual machine's virtual keyboard when the machine window is selected. This is a per-VM setting and it is disabled by default. To enable this for a VM use the following “VBoxManage" command:
Note: This is an experimental feature and works best when using the internal keyboard of eg your MacBook Pro.
