Apple should make their finance department use Numbers, it would be fixed in no time. I swear nobody at that company has ever opened Numbers, I don't understand how it can be so broken for so long.
It seems to be a pattern with apple apps in my experience.
I don’t hate myself enough to have a Mac but I have an iPhone and there are so many bugs in apple supplied apps (mail, safari, iOS itself, iCloud) that apple have known about for years. And yet these bugs are still there with no desire from apple to fix them.
I don't have any inside information so perhaps an ex-fruit can shed some light on it, but speculating it seems that Apple's organizational structure implicitly encodes the waterfall pattern.
Apple has divisions for Design, Engineering, etc instead of divisions for products as is more normal. So sometime 20 years ago someone in the Design department designed a spreadsheet app, and they've been stuck with it ever since because Engineering isn't empowered to say to Design that this UI fucking sucks. Even though the app is otherwise regularly updated.
You see the same with Tahoe, when users report that they can't resize the window because the corner radius is so large that it excludes the hit box, Engineering does their best to move the hitbox, but they are not empowered to make the obvious fix which is to reduce the corner radius because that would be a UI change and those only go through waterfall.
I love the Calligra user interface compared to Microsoft Office or LibreOffice. It feels like it exposes features and information well in the way the best KDE apps always have.
