Hey, I have a MacBook (aluminum unibody); I recently installed VMWare fusion 3 and put a copy of Windows 7 on there. Set it to utilize one core at first, but that was painfully slow, so I let it use two cores with 1.3mb of RAM. Still laggy. It was bad enough for me to not want to use anymore and uninstall... Has anyone else experienced problems with VMWare? Not sure if it's my hardware or the software causing the lag. Thanks.
