I have a MacBook Pro and a basic understanding of computers. Recently, I enabled hidden files and started browsing through folders when I found videos and photos showing ordinary everyday scenes that I don't recognize. I'm certain they were never sent to me through messages, texts, or social media. My Mac normally stays at home, AirDrop is disabled, and I usually block network connections with my firewall. I bought the computer brand new several years ago and have always had possession of it. What could explain these files being on my Mac?

Check the files’ metadata first. It may show the original device, creation date, or application that generated them. They could be cached media, temporary files, or thumbnails created by an Apple app rather than files someone intentionally copied onto your computer.
The folder location matters a lot. Hidden system folders often contain cached previews, application data, migration leftovers, or media created by software. Make a copy of the files, note their exact paths and timestamps, and check which application or process owns that folder before assuming there was unauthorized access. A brand-new computer that has stayed with you makes an old-owner explanation less likely, though checking login history and running a trusted malware scan would still be reasonable.
The metadata says they came from an iPhone 15, while I use an iPhone 17, so I’m still unsure how they got there.
