Question: running out of storage
I have a MacBook Pro (Retina, 13-inch, Late 2013) and I am almost out of storage, of which most of it is taken up by my photo library. I synced my photos with icloud storage so that I could free up some space, however my photo library hasn't been deleted off of my macbook and I am unsure as to whether deleting it would cause it to be deleted on icloud. I've backed it up on an external hard drive as well, but I'd rather be 100% sure that my library would be preserved on icloud if I delete from my macbook than have to import all of my photos again.
Could someone please advise? Thanks!
