If you need to run Windows applications on your Mac, VMware Fusion is one of the best options out there. I've been using it since it first came out and, I continue to upgrade each year. Some of the notable features of version 7 are:

• Yosemite support (as a host computer or inside a virtual machine)

• Windows 8.1 support

• Increased app nap support for better power efficiency

• Retina display optimization

If you are upgrading from version 5 or 6, it's only $49.99. For new customers, it's $69.99
