El Capitan Mail - Syncing with Gmail
I updated my MacBook Air to El Capitan today. I've used Gmail for a long time, and always access it through the Mac's Mail app. A strange thing started happening with El Capitan: it downloads each e-mail twice, about 20 seconds apart. The first time it puts it in my inbox, and also places a notice in Archive. Then it downloads it a second time. I get two alerts, one for each download. How do I stop this unnecessary redundancy?
Speaking of Archive, what's the point of this? I've never used it. It has three subfolders: On My Mac, one for my Gmail address, and a third one with an identical name as the first subfolder. All of my mail goes into the Gmail address Archive folder. Not certain why, what should I do about these extra folders, or even why I should care.
