Thank you for the response, Ron. Can I go ahead and install get the upgrade installer for OS 9.1 or higher on my OSX G4? Or do I need to wipe OSX away first, as a friend reccommended? If so, how do I do that? If it's not necessary to get rid of OSX first (as I hope), I will just install the upgrade as noted above and I'll be in business! Yes? Thank you, Donald
