Running out of space, so need to move iphotos library off MBP to EHD. 1. I dont especially want to have to hook EHD up everytime I want to open iphotos, sync a phone, etc. What are my options? Can I move library to hard drive, then continue populating iphotos on the computer then move photos over to hard drive every so often? 2. Should I move library before or after I upgrade from Snow Leopard to El Capitan? Does it matter? If I move the iphotos Library to hard drive will I be able to access it via new photos app in El Capitan?
