new entries revert to "new event"

Just within the last few days, Calendar has begun consistently misbehaving. I create a new event, assign it to a calendar, fill in information such as time and notes. I close the editing window, the new title displays (I'm using Month View) for just a second, and then it reverts to "New Event," and everything I've entered is lost. Oddly, when I enter all the information a second time, it always seems to stay.


As far as I know, I haven't made any changes to my OS (10.9.5) or to Calendar (7.0), neither via their settings nor any other way. FYI, I'm using iCloud to sync between the calendars on my MBPro and my iPhone (4S, running 7.1.2).

MacBook Pro (13-inch Early 2011), OS X Mavericks (10.9)

I just realized it might be a good idea to search my own Calendar for "new events," and I found half a dozen spread over the last decade. That's not too bad, and it's even possible that they might all be actual New Events that didn't get filled in with any info... although I doubt that. Obviously, it's distressing to find that data may have been lost, without any way of knowing what it was.


One thing I noticed, is that now Calendar is showing those dates from long ago, when I lived in a different time zone, with "CDT" and "CST" appended to the times. I don't remember Calendar ever doing that before. I wonder if that might be related to this problem we're having? Somebody suggested turning off the local time zones setting seemed to help, although as I recall someone else popped up pretty soon thereafter and said it didn't...


I wonder if we're gonna have to go down and start picketing our local Apple Stores to get the "geniuses" there to fix this!

Yes, upgrading to Yosemite didn't solve the problem (tried on a clone HD, i'm on mavericks now).

Maybe a clean install from scratch can do, hadn't tried.


Upgrading to Yosemite won't solve this. We've been running OS X 10.9.5 for months & this problem just started happening (within the past month). But we might have found a solution: got to Preferences > Advanced, and deselect "Turn on time zone support." For us the problem stopped immediately. Knock on wood.

is there anyone out there that has upgraded to yosemite and had this problem resolved? If so, when did you do the update? I just had a conversation with a senior rep. bc the last one i talked with has refused to schedule a call back and we keep playing phone tag. This last rep. told me the official apple fix is to update to yosemite even though he could not point me to any official apple info. on the fix and could not guarantee that it is a 100% fix and could not tell me how I could revert back to mavericks if the fix did not work. on top of that, he basically said that the info on this site is not apple approved or supported. also, mid way through our conversation, after I of course had given them my call back no., etc, the line went dead and I received no call back nor did the rep give me his contact no or contact info.

Do not upgrade to Yosemite if you plan or want the option to go back to Mavericks. I upgraded last Fall and there was a bug that caused a "leak" from my email which caused my RAM to continually max out making the computer inoperable. I'm sure the problem is corrected by now but through the fiasco of trying to restore my Yosemite back up to Mavericks with no success I learned that Yosemite repartitions the hard drive so I could not go back. The only solution was to buy a used iMac with Mavericks installed on it and I was somehow able to restore my Yosemite back up to that one. I was told however that when I'm ready to upgrade to Yosemite, to stop my backups from running until I'm completely satisfied with Yosemite. The idea is you should be able to restore your Mavericks back up and go back to Mavericks. So check into this idea before you upgrade!

I had a similar battle with Apple Tech and we came to the conclusion that upgrading the Yosemite would solve this. This was at great expense as we had to upgrade other software that was not compatible to Yosemite. I am not convinced that it has completely fixed the problem but we do have less issues. However there are a whole new set of bugs Yosemite brings.


It seems Microsoft (whoops apple) can't even stop the screen saver reverting back to the original picture every couple of weeks.


We upgraded 2 weeks ago and all machines that use the ICAL network need to be upgraded.


Good luck

I have read through a lot of the posts but not all. This has happened to me too. I find it completely unacceptable and no, I will not 'upgrade' to Yosemite (for all of the good reasons listed in previous posts). So, not sure if this option has been mentioned. I simply FIRED my Apple Calendar (see ya!) and replaced it with BusyCal. No issues. Gone. And, as often happens in these situations, I end up with a LOT more capability than I was stuck with previously. BusyCal syncs across all of my devices, it is stable, more robust and capable (icons, banners, lots more command options, far more sophisticated interface, etc.). And it is a complete work around to the ApplCal problems we have been having. I'm sure there are other options out there too.


Highly encourage you folks to move on to a better Mac calendar option. It works. Learning curve is light. You won't be sorry. And you'll be back in the command chair with your own solutions.
