If this isn't the right place to ask this, I apologize. I also hope that I write this in a way that makes sense.
on my MacBook hard drive I have a folder of photos from an old computer. I want to move certain pictures from my photo app library to this folder on the hard drive. what would be the best way to do this? im fine with keeping a copy in the photo app, but I'd like to back up some of these pictures on the hard drive. thanks in advance.
