Moving photos to external drive - nervous
Hey there, I'm an inexperienced Mac user, want to copy my entire photo library to an external drive (I have a Seagate 1TB external drive), but am nervous I'm going to accidentally delete them. My entire photo library is also currently in iCloud, what's the best, safest way for an inexperienced Mac user to copy them to the external drive?
Thanks in advance
