From what I can see on posted screenshots, the hard drive icon "Macintosh HD" is still based on a 3.5" steel-clad drive!
Isn't it about time Apple acknowledged that many of us use SSDs - of whatever sort?
Does it matter? - hardly at all. Very simply, it is just annoying that every single time I see a hard drive icon, my thoughtline gets diverted to "I remember when hard drives looked like that..."
However, it would be rather nice to get realistic drive icons - especially for external drives. My Samsung T5 is a black device. But the icon is a strange orangey colour and the wrong shape. If not automatically, I can see why outer cover colour might need to be manually selected but, for widely distributed drives, more accurate images would be nice.
