In case you need to visit the dark side, 2008-04-25 Works beautifully - fast, reliable and flexible. The only thing it won't do is write DVDs, but everything else is just as advertised. A much more flexible tool than Boot Camp, and lets you keep your Mac up when you need to use Windows. Two operating system in one, 2008-04-20 I really like to be able to run some Windows programs in my Mac. The only con I find is that sometimes it falls, so you have to force quit Parallels. I hope they solve this soon. 1 of 1 customers found the following review helpful: doesn't work, 2008-04-20 i cant get it to run. went back to boot camp for now. also manual was hard to follow. 1 of 1 customers found the following review helpful: VM WARE is much better, 2008-04-20 This product would not successfully run windows on my Macbook in anything but "safe mode". I tried both the "transporter" install option (this is the sole reason for purchasing the product as I wanted to run my Thinkpad as a virtual machine within my Macbook Pro) and I also purchased a brand new copy of windows and tried to build a new virtual machine from scratch - on both attempts Windows would not boot. I downloaded the most updated build of parallels as required for use with Leopard...I attempted to resolve the many hardware and driver conflicts... I tried to get tech support from parallels with no luck at all. Eventually I downloaded VMware Fusion and it worked on the first try - no issues. Parallels was a complete waste of time and money. Great Price!, 2008-04-19 I'm a new MAC user so I do not know of many applications out there other than Parallells or Fusion that lets you create this virtual machine. All I do know it is serving its purpose and purchasing it from Amazon saved me over 20 bucks!
