OS X Yosemite 10.10.5
Don't know as a programmer expert friend did it
Don't know if this computer was using icloud . Have only just bought a new iphone 6s+ this year.
I don't understand what is duplicated as have strange complement files in my ALL files folder on FINDER.
Have a Time machine...
I have bought a new Macbook Air and in All MY FILES i seem to have duplications galore. When I delete it says I will remove it from iCloud. Do I need it in icloud and why is it going to icloud. How do I get rid of duplications????
