I know a lot of people are concerned that the white bezel surrounding the display will be distracting. In practice, I found that it just disappears. If there can be such a thing as a muted white — a white that most certainly looks white, not light gray, but yet not white white, this white is that white. I didn’t need time to get used to it

There is a lot of talk regarding the white bezel of the new iMac. I still don’t know what to think about them. They make it look like if there was a white masking tape all around the display. But the thing is, considering the fact that Apple’s macOS overall user interface is so “white-ish” in general, this should help make the bezel kind of disappear in reality and just be an extension of the user interface.
