Hi, I have some weird problem with syncing my Reminders between my iPhone, iPad, Mac mini and rMBP. First, the iPhone, iPad and Mac mini are always online and always work in sync. If I change something on my iPhone, it's there almost instantly on my iPad, etc. When my rMBP is online, it's the same, no problem. But, I work in a place with no Internet (in fact, we use a proxy for some apps, and iCloud is blocked). So, during all the day, my rMBP cannot get new content from iCloud. I make sure to not modify anything on my rMBP during this time. If I must change a Reminder date or check a completed one, I do it on my iPhone. The problem happen when I go back home in the evening. I open my rMBP, connect to my home wireless and iCloud start syncing. Most of the time, everything is correct. But sometime, my rMBP revert all the changes I made during the day on my iPhone. This is really annoying because sometime, this means 10-15 todo change date, etc. Anybody got an idea?
