Recently, VMware released an update to its popular virtualization software that adds many improvements. It’s called Fusion 4.1 T and it is promised to get rid of any bugs. Although, the biggest improvement is the applications ability to run older versions of Mac OS X Leopard and Snow Leopard.It has been known for a long time that Fusion can support Mac OS X Leopard or Snow Leopard virtual machines, but Apple’s licensing prohibits this.
Now, Apple has altered the Mac OS X licensing terms with the release of Mac OS X Lion. The new software license allows users to install and use virtual machines running the client or server version of Lion on their Mac. But, it doesn’t mention anything about older versions of Mac OS X , hence its assumed that its prohibited.
Apparently, VMWare is leaving it up to the user, whether they want to virtualize either of the older versions of Mac OS X. If a user tries to install Leopard or Snow Leopard in Fusion 4.1 they will be prompted with a dialog that asks: “Verify that the operating system is licensed to run in a virtual machine. ” If you select Continue then Fusion will go ahead with the installation of the operating system leaving the decision to go ahead entirely in the user’s hands.
While there are some questions about the legality of running Snow Leopard or Leopard in a virtual machine, there’s no doubt about the utility of such a feature. First off, it would be a boon to developers and tech-support professionals, who need to verify how software works on various versions of OS X. But it would also help out users who rely on PowerPC-based Mac software—programs that won’t run in Lion because of Apple’s abandonment of the Rosetta code-translation software.
