Calendar on OS X, which has always had trouble with disappearing events, is now waiting several minutes to perform its disapparation magic, so I an enter an appointment, wait a while to confirm that it stuck (a habit I've learned is essential over the years), be sure it’s safely recorded, and even then; poof! — it’s gone (or turned into a generic “New Event”).

I simply can’t rely on Calendar for anything any more!

Is there a way to configure Calendar so that appointments that I enter don't disappear or revert in this way?

  • Is it trying to sync to iCloud & failing? Poor connectivity, dodgy Wifi etc? It just has all the feel of 'server lag', dropped packets, high latency etc. If that is even vaguely a possibility, test with no internet connection & see if it holds until you do connect [or even if that fixes it entirely]. Even if inconvenient, it might be pointing the way. – Tetsujin Nov 23 '15 at 17:21
  • I don't think so. If so the issue isn't on my side. I have fast reliable network connectivity. It does feel line a sync issue, but the problem seems to be on the Apple end of things. I've logged out and back in again, and this has persisted across several OS X upgrades (and one machine transfer). – orome Nov 23 '15 at 17:24
  • Though unrelated to iCloud; I work helpline for an online gaming structure… where the opening 'fix' for anything that feels network-related is "Reboot your puter & all networking hardware & try again" By heck it's trite, I know, but the number of times it actually works… – Tetsujin Nov 23 '15 at 17:29
  • I've done that several times. It has no effect (nor do updates, killing processes, or even machine transfers). – orome Nov 23 '15 at 17:33
  • I had a feeling you would have done that, over such a long time period. I'm out of ideas, sorry.. but it still 'feels' like network latency – Tetsujin Nov 23 '15 at 17:44
