On Wednesday, virtualization softare maker VMWare released version 4.1.1 of its Fusion software for the Mac.

Similar to other virtualization software packages, VMWare allows users to run alternate operating systems such as Windows and Linux distributions on Intel-based Macs at native speeds. Other features, such as Unity, allow users to run and minimize Windows applications from the Mac OS X Dock.

The new version, a 180 megabyte download, can be found here and offers the following fix:

Fusion 4.1.1 retails for US$49.99 and requires an Intel-based Mac, 2 GB of RAM, Mac OS X 10.6.7 or later (10.7 recommended) and a copy of Windows (if you’ll be installing Windows).
