Over the past month I have made CD and DVD disc with jpg files. They open on my MAC OS 10.6 and my PC but not on other peoples MAC who have updated to 10.7 & 10.8 and the
newest MACs. The disc open on the PCs. Does anyone know why? I can easily upgrade to Toast 12 but need to know if this will resolve the issue. Of course I select MAC & PC format. This
has worked fine for years.
