update to 10.9.5 messed up my Mac mail?
I was perfectly happy using Mac mail with my gmail account but the Mac mail interface and behavior were very different and aggravating after OS update. Main problem is the inbox in mail tries to download all ~6,000 msgs each time (13,00 msgs total in all folders), and new folders were added, such as VIP, All Mail and Google Important. Pretty sure I need to change gmail settings but even that program interface looks different. Frustrating.
