Mail app IMAP accounts got messed up after upgrade to Sierra completed (from Mavericks). One IMAP account got completely lost, e-mail messages saved to privat and local message boxes are saved. Few other messes in accounts definitions more. Is it possible to import manually accounts definitions...
Now I can see that when I see a video on YouTube on the defenitions specs I can select 1440p, but Apple never announce that you can see 2K (1440p) on your iPad Air 2 or iPhone 6s Plus, so, can I really see 1440p on this devices?
