Question: Copy home DVD to hard drive
I have Sierra on an iMac.
I have a binder full of home movies.
I have a WD external hard drive that is storing all of my still photos - and works great with my Mac.
How do I copy my home movies from the DVD-R disks to the hard drive in order to get rid of my binder full of disks? I can't find anything online.
iMac, macOS Sierra (10.12.3)
