VMware Fusion for Mac is a desktop application that lets you create and run virtual machines on your Intel-based Mac. VMware's first product for the new Intel Macs makes it easier than ever to take advantage of the security, flexibility, and portability of virtual machines. Fusion provides an intuitive user interface for creating virtual machines, and for running preconfigured virtual machines created with VMware Workstation, VMware Server, and ESX Server. With Fusion, you can run your favorite Windows applications on your Intel-based Mac. You can also download virtual machines from the VMware Technology Network (VMTN) Website, which has a growing library of virtual appliances with a wide range of pre-installed and preconfigured applications and operating systems.

Features of VMware Fusion:

• You can use 32-bit and 64-bit guest operating systems in Fusion virtual machines. Fusion supports Windows, Linux, and Solaris operating systems in virtual machines.
• Fusion supports all Intel Mac hardware, including the new 64-bit Mac Pro and iMac.
• Your virtual machines can have multiple virtual processors, taking advantage of the Intel Core Duo chips in today's newest Intel Macs.
• Fusion supports high-speed USB 2.0 for a huge range of devices. Even devices that do not have drivers for Mac OS X will work in a virtual machine.
• Virtual machines seamlessly integrate with your Mac: you can cut and paste text between your Mac and your virtual machines, drag and drop of files between your Mac and your virtual machines, and create shared folders on your computer so you can easily share files and folders between your Mac and your virtual machines.
• You can burn CDs or DVDs to your Mac's rewritable optical drive from within your virtual machine.
• You can resize your virtual machine's display dynamically.

New and Improved Features in Beta 2

This Beta 2 release of VMware Fusion for Mac includes the following new features and feature improvements:

• Experimental 3-D graphics support — Play a selection of DirectX 8.1 games in Windows XP Service Pack 2 virtual machines.
• Snapshot feature — Roll back your virtual machine to a known good state when something goes wrong in your virtual machine—for example, when your virtual machine picks up a virus, or when a software upgrade causes problems.
• Improved networking — Automatically bridge to the computer’s primary network interface.
  Full support for Airport wireless networking, including virtual machines behind a NAT firewall and bridged to the local Airport network.
  Support for up to ten virtual network interfaces
• Improved Microsoft Vista support — Support for Microsoft Vista Business, Enterprise, and Ultimate editions.
  Complete VMware Tools support for Microsoft Vista including copy/paste, dragging and dropping files, shared folders, and screen resizing.
• Improved hardware editor — Add additional virtual hard drives to a virtual machine for needed capacity.
  View the physical computer's battery status in the virtual machine.
• Improved full screen mode — Support for plugging and unplugging displays while virtual machines are in full screen mode.
  Improved usability: an on-screen tip shows how to enter and exit full screen mode easily.
• Experimental support for Mac OS X Leopard — You can now install and run VMware Fusion on Mac OS X 10.5 (Leopard). Support is experimental because Mac OS X 10.5 is not yet released. Fusion will support the release version of OS X 10.5 in the final VMware Fusion release.

Bugs Fixed in Beta 2

This Beta 2 release of VMware Fusion for Mac includes the following improvements and bug fixes:

• Improved keyboard and mouse support — Third-party graphics tablets, keyboards, and mice no longer interfere with keyboard and mouse input.
  Support for plugging and unplugging input devices while virtual machines are running
• Improved CD/DVD support
• Better support for mounting and unmounting discs in virtual machines
• Quicken Scheduler corrupts keyboard and mouse input in virtual machines — Offer workaround to disable Quicken Scheduler when it is detected.

Games Compatible with Fusion Experimental 3-D Acceleration

VMware testing has determined that the following games, running in Windows XP Service Pack 2 virtual machines, are playable with Fusion experimental 3-D acceleration:

• Aliens vs. Predator Demo
• Breath of Fire IV
• Grand Theft Auto III    (Tip: Set the Display Setup option Trails to OFF.)
• Hitman 2
• Lord of the Realms III
• Max Payne 1
• Max Payne 2
• Need for Speed Porsche Demo
• RalliSport Challenge
• Tony Hawk 3
• X-2 Rolling Demo

The fixed-function tests in 3dMark2001 operate successfully in Windows XP Service Pack 2 virtual machines with Fusion experimental 3-D acceleration.

If your Mac uses the Intel GMA 950 graphic chipset (found in Mac Minis and MacBooks), you may experience performance issues with 3-D enabled. Try increasing the memory for the virtual machine or lowering the resolution of the game.
