VMware Fusion can run any of hundreds of operating systems provided by the user, including many older versions of macOS, which gives users a way to run older Mac application software that can no longer be run under the current version of macOS, such as 32-bit apps and Rosetta ( PowerPC) apps. VMware Fusion 1.0 was released on August 6, 2007, exactly one year after being announced. Much of the underlying technology in VMware Fusion is inherited from other VMware products, such as VMware Workstation, allowing VMware Fusion to offer features such as 64-bit and SMP support.
VMware Fusion uses Intel VT present in the Intel Core microarchitecture platform. VMware Fusion, which uses a combination of paravirtualization and hardware virtualization made possible by the Mac transition to Intel processors in 2006, marked VMware's first entry into Macintosh-based x86 virtualization.
