The annoying thing with Finder is when you're in a folder, you start to search, and then it defaults to "This Mac" and not the god damn folder you're in.
Bloody daft.
Bloody daft.
With the Finder open, go to Settings > Advanced, and change the drop-down at the bottom to "Search the Current Folder". This is something I do on the first run of every new Mac I set up.
"Search this Mac" should be confined to Spotlight OR as a fallback if the local folder doesn't return anything.
