Apple Mail in Mavericks treats Gmail accounts differently than any previous version of Mail did. Although some of the changes are quite clever, the implementation has flaws. Your mileage may vary, of course, but I’ve seen a number of folks on Twitter complaining about some of the same things I’ve found. Here’s what I’ve observed and what you can (and can’t) do about it.

I mentioned “strangeness” with Mail in my review of Mavericks. Joe does an excellent job at documenting what’s going on and why.

I’ll let you guess what other old feature Mavericks broke in Mail (keep reading Joe’s article until the end).
