Finding duplicate files on external drives

You dig into the little things macOS quietly does for you, starting with the surprising truth about Clipboard History and why macOS 26 might feel slower than you’d expect. You explore ways to rein things in, from taming runaway apps to making better use of iPhone Mirroring and clever video capture tricks. Along the way, you’re reminded that old hardware still has value if you give it purpose, and that blind trust in AI troubleshooting can lead you astray faster than it helps. This is where staying curious beats staying complacent, and where “Don’t Get Caught” is more than a catchphrase.

Then you move into the real-world problem solving that defines Mac Geek Gab: networking quirks that break expectations, WiFi settings that ignore reservations, and router updates that change the rules midstream. You also get clear, practical guidance on buying the right Mac, migrating only what you actually need, hunting down duplicate files, and reclaiming menu bar space from the notch. Even photo libraries get a reality check, helping you decide what truly needs to live inside Photos. It’s a fast-moving episode packed with answers you can use immediately, designed to keep your setup efficient, intentional, and frustration-free.
