Finder
It has been one of the oldest problems on Macs, when a document shows with the wrong icon. Why, and how to fix it?
You try to open a document – in this case, one of Firefox’s bookmarks – and nothing happens. What could be wrong? It turns out it’s a bug, of course. But where?
Why do the Open File and Save File dialogs normally behave differently with respect to tagged folders? It’s a question of semantics.
