I have a few problems here actually, the first being that reminders can be created on one device, ML Macbook Pro, iPad or iPhone and it'll be there, but if I check it off, it doesn't check off on the other devices, is this how it is or is it not syncing properly? I've also noticed that my PhotoStream NEVER resets, I have to delete it myself. I've tried turning it off and on again on all my devices, but it does the same thing over and over. I believed it was meant to reset after 30 days? I might be wrong and just picky about both these things, but is there a fix for either of them? All iDevices on iOS 6 and Mountain Lion is fully up to date. Thanks everyone for the possible help!
