Snow Leopard, aka Mac OS X 10.6, was released in June 2009, and it represented the last version of macOS to run older PowerPC based software. If you want our office to set this up for you (which we can do remotely), please email to schedule an appointment.
It has been verified on Parallels 16.1.0. This is a technical post on how to get the Snow Leopard OS running on a Mac in Parallels Desktop, so that older Apple software can be run on a newer Mac.
