The reason is that Apple keeps changing settings. Seems like almost every week I try to open an image file and find that Apple has changed it from GraphicConverter to Preview, or .csv from LibreOffice to Numbers, or .mp3 from Amadeus to Music. I have many times restored all of these to my preference, and it keeps happening. It’s been filed in bugreporter long ago with no response.
I have an AppleCare on this laptop. Might it be worthwhile calling them? When I had a problem with Mai.app, it was weeks of trial and error before the guy declared it “fixed.” They have ignored two or more messages saying “no, it is NOT fixed.”
