I have read that iOS 9 and 10.11 will utilize iCloud Drive for syncing Notes, Calendar, Reminder, etc between Apple products instead of IMAP. I haven't read all the details regarding iOS 9's new features. So, is the transition from IMAP to iCloud Drive happening? I still use Mountain Lion on my main machine. So I was wondering whether I still will be able to sync Notes, Calendar, etc on my iMac. Furthermore, will Fantastical 1 still work? Thanks in advance.
