This is a first. I've found Spotlight search on Mac desktop to be absolute rubbish. I never actually find what I'm looking for.
I'd misplaced one of the graphics I need for the next @vintageapparatus video (one with the text in the footer), and my old standby 'find' was... not finding it.
What the heck, says i - Finder -> Search -> blahblahlogo
AND IT FOUND IT.
Years of swearing at Mac Finder ... well, are still there.
