VMware has released version 5.0.2 of its Fusion and Fusion Professional virtualization packages, fixing a number of bugs. Notable changes include USB 3.0 stability improvements, a fix for a problem affecting multiple-monitor setups under OS X 10.8 Mountain Lion, improvements for the Microsoft Office 2013 preview and Windows 8 installations, a solution to a bug that caused the library and the Fusion start menu contents to get out of sync, and more. Known issues that remain include a black virtual machine screen on some Mac Pro systems running Mac OS X 10.7.5 and problems with upgrading directly from Windows XP to Windows 8 inside a virtual machine.

Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
