Hi folks, Is there someone who knows Mac software inside and out who could help answer some basic questions about OS compatibility with browser and software programs? I've gone on the Apple Forums, seen conflicting info, and I've called the Apple Store in Holyoke, but it seems my calls keep being rerouted to someone out of state and they don't seem to have the answers. I am on a MacBook Pro, c. 2013. I can forward all the software particulars via email or we can talk by phone. Thanks :-) Deb
