If I want to look up the weather forecast on my macOS Big Sur, I get a 404 page.
MacOS redirects to a URL with the
locale=en_TR query parameter in it. That looks… wrong? Anyway, The Weather Channel refuses to serve me the forecast with that locale, so I get a 404.
I only had one lead about what might be causing this. My OS language is English but my keyboard is in Turkish. I thought “A-ha!” – I got this. However changing the keyboard language didn’t fix it.
Sounds small but it’s the single most annoying problem I deal with day to day. It’s the little things that hurt the most.
