A client is stuck with software that will not run under Mac OS 10.7, but that operates under 10.6 Snow Leopard.<br />

They have to buy a new MacBook Pro, which has 10.7 installed (and possibly Mountain Lion)<br />

Is there a chance that the computer can be erased, and a version of 10.6 installed instead?<br />

I figured that I could go to the Apple Store with an external USB drive with Snow Leopard installed, and try and boot from the USB, to see if it will work. &nbsp;I'm hoping for a definitive answer here.<br />

Can a newly-purchased Mac be downgraded to Snow Leopard  10.6?

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.

Mac OS X

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
