I just installed I Book Essential on my new MAC. I went crazy and put all my digital videos on the MAC and completely filled it up. When the I Book transferred everything, it gave a warning that it was full (some of the movies didn’t come over they still showed up yellow). I thought maybe I could go back to the back up preference choice and change it from all the file types to just movies. When I push the apply and run “back up” there is no activity, is that because the setting can’t. be changed after it’s done.
I was trying to delete some things manually. I opened the I Book and the finder next to each other. If I deleted something from I Book, it automatically deleted from the MAC as well.
