I would probably be getting one of these if not for the Mail problems on Catalina. (I have a small number of messages On My Mac, which I could deal with somehow, but the inability to choose column settings would annoy me.) Or I might anyway.
Sometime in the past, there was a pricing peculiarity on Apple’s order pages that meant it made a big difference how one arrived at the final configuration of a new Macintosh. Does the path to a final configuration make any difference with this MacBook Air?
