Saving photos to an external hard drive
I have all of my photos on an old Mac laptop that I am now trading in with Apple. I wan to copy/save/move all of these photos to an external hard drive and just keep them there. I don't intend to transfer them to my new Mac but I want to be able to see them when I want to look at "old pictures."
What is the be approach to taking these photos off of my old laptop and transferring them to the hard drive? Thanks for the help.
MacBook Pro 13″, macOS 10.15
