Sucks here tonight - iOS9 stopped supporting older versions of iTunes. I cannot sync my iPhone that is now running iOS9. I am still using Snow Leopard because ProTools 8 is my main workhorse. It wont run on Lion - Yosemite. I am not going to pay $1,000 for ProTool 9-12 just so I can sync my iPhone. I am thinking of zero formatting my drive and installing Snow Leopard on one and Yosemite on the other. Will the Mid-Summer 2010 Intel Mac Mini run Yosemite?
