Move original photos off of my Mac
I have my Photos library backed up in iCloud. I just bought a new Macbook Pro. Realized while setting it up that the default was to download the original files to my Macbook. How to I delete the original files from my Macbook and just keep the thumbnails of what I have stored in iCloud?
MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.3)
