Parallels Desktop 9 for Mac is this year's update to perhaps the most popular virtualisation program for OS X. Parallels is trying the hard to cram in every possible features it thinks you'd want, along with several we wish it wouldn't. New options include Apple's PowerNap, which now extends to Windows. This is a spin-off from Intel's low-power mode that allows PCs with recent Core processors to entertain certain tasks when the computer is asleep; in the case of applicable recent Mac models this could include Time Machine backups, downloading software updates and checking for email. Personally we find the idea of our computer periodically waking up and doing work unbidden a little creepy. And now you can extend the idea to let Windows apps do the same; an even scarier thought actually. USB 2.0 has been supported from the beginning. More recently USB 3.0 has been included for manual activation with some success, depending on device.
