I just did a full restore with Yosemite. All went smooth until it came time to look for all of my email/calendar/messaging, and contacts accounts. Only Apple's iCloud account, not my Gmall, Yahoo, etc showed up to the dance. I had to manually re-enter them. My Safari passwords were present though. The accounts on my iPad remained unchanged after the re-entry. I am wondering why this occurred and how will this affect my iPad in the next day or so if at all. I never had this problem before with any other Mac OS. Thank you. MacBook Pro with Retina display, OS X Yosemite (10.10), 15 inch retina. Mid-2014.
