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.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
