Q: new entries revert to "new event"

On my MacBook Pro, I set an appointment in iCal and after doing that, it disapears.

I go into Preferences and turn the iCloud sync for the calendar OFF and imediately again ON. Et voila: The appointment(s) macically show up again.

I could imagine that it has to do with...

A) different timezones on mobile and laptop and/or

B) the refresh-time

Something new I discovered and don't remember seeing anyone post about it.  Seems that if I create an event on my iMac calendar program by using the + sign (quick event), the event stays as entered on whatever calendar I choose.  On my iPhone all is good too - never had an issue with that.

However, if I create an event in calendar on the iMac by double clicking on a day, it does still revert to new event and wipes all the info for the event.  You can witness by being logged in to iCloud calendar and look at that while you enter the info on computer calendar and see that as soon as you double click on computer calendar an events pops up iCloud as new event and this will replace the info entered on your computer.  Anyone else??

I have this problem with all versions of Calendar on my Mac.

It seems that my issues are resolved. For a week or 2 my calendar entries on OSX 10.7.5, 10.9.5 and IOS online don't revert back. Today I noticed that Apple changed some things behind the scenes. When I entered a new calendar entry on OSX 10.9.5, I got a warning from Little Snitch asking me to give iCal permission for connecting to gsp1.apple.com on port 80 and another connection I forgot to jot down. I think it had to do with apple maps for location data. I never got these warnings before and since I didn't change anything nor were there any updates for iCal in the period of the issues, I presume they have changed something in the back end. Anyone else experienced some change?

nope, no change - still reverting to blank new event

anyone???

Today I made a new entry on a machine running 10.9.5 and again, it reverted back to 'New event’. The machines running 10.7.5 and IOS 7 and 8 are still OK.

Nice one! [+] works for me too. Will try and remember to use it from now on. Apple's stance unbelievable! A calendar application that screws up event names and leaves a trail of missed appointments, events, etc. is absolutely useless in my book. As Steve would have said to the Calendar guys: 'You should hate each other for this ****-up!'

I never knew that right-click (in my case, control-click) option existed. This both pinpoints the problem and provides the workaround. THANK YOU !!

The quick event option seems to work here too on 10.9.5.

Thanks everyone (except Apple) for your help on this. I'll try the work arounds. Like everyone else, this is a real problem for my office (not JUST a productivity suck). A calendar app that forgets events, not addressed by Apple?!? This is completely unacceptable. Presumably because there is a newer OS? Is it even fixed in 10.10 or 10.11?

And that's the real rub.

I am generally an Apple fan, and like their hardware. But Google is kicking their *** when it comes to the cloud and office/productivity apps. And most third-party apps out perform Apple's. This is a fundamental reason why Apple has not been, and may never be, a legitimate business solution. This model where native apps never get updated, and rarely get fixed, until a new OS is released, just doesn't work for most businesses. I can't update an office full of computers once a year. It takes six months for me to shake out all the bugs from updating. I can't do that every year! Apple's OS is free, you say? So what! The third-party apps that get broken upon update, and must be upgraded to run, are NOT free. Updating an OS, on one machine alone, including labor and lost productivity, can be $1000+ dollars!! How am I supposed to justify that expense every time an app stops working.

Apple, you want to be taken seriously? Do better. Release better apps. Stand behind them when they don't work. (Gee, what a concept...)

So I am left to complain, to no one in particular, especially not Apple, who doesn't seem to support their own products, let alone this forum.

I am (not so glad) to report that, in my experience, the workaround reported by user "hueyo" does not work for me. No matter what I do, or do not do, any newly created event will always revert back to "New Event" within a few seconds of closing the details window. This happens when I use the "plus" to add new events or create them by clicking on the calendar itself and regardless of whether I change the assigned calendar.

I am using 10.9.5 on a MacbookPro i7 2.4Ghz with 16GB RAM. I gather from these discussions that the only option for a real solution here is going to be an upgrade to Yosemite, but my business depends on software which is not yet compatible.

The only option I have come across that works is to create a new event with the correct title (ie. Appointment with Dr. Smith), copy that title, close out of the window and wait until the event reverts back to "New Event", then re-open the event, paste the original title back in, modify other details, and then close the event and wait a few seconds to confirm that the event doesn't revert back again. What should take seconds can take minutes.

I've been using Apple computers since 1996 and this has got to be the most annoying bug that has ever affected me. I think what bothers me the most is that it has caused paranoia about even the most basic operations within the Apple product software line – not just the calendar, but iTunes, Contacts, Mail, etc... I find myself double and triple checking everything and worrying that I may not receive a notification of a critical event when needed or not have access to updated contact information when I need it most. The loss of productivity is staggering, and all this from a closed system that is ostensibly marketed as a solution for enhanced productivity!!!! Unbelievably poor customer satisfaction right now.

As an aside: I must reiterate to everyone that these discussions, though they exist at apple.com, are not officially monitored by Apple technical personnel. So anyone waiting for a reply from Apple is going to be waiting a looooong time, and anyone hoping to vent or receive troubleshooting support from apple will need to contact Apple some other way! Just thought I'd throw that out there.

I feel your pain. I'm still stinging from years ago, when one of Apple's other cloud attempts was buggy and making me and everyone else crazy. I was having trouble getting data to sync. Well aware of your warning about this forum, I resorted to contacting Apple directly. We worked on the problem to no avail, but what I'l never forget was the comment from the Apple tech, who concluded (paraphrasing) "Apple doesn't warrant the use of this software for business use." As if to say that Apple "productivity" software is meant for, what, home use, I guess, and that one shouldn't rely on it for important things like a business. I was floored that Apple would excuse itself from getting it's software to work correctly (as advertised) because they determined some how that most of the people that use it don't have any really important appointments?!? Well, maybe that's because nobody that needs to really rely on an online calendar trusts Apple to get it right, because they never have!

I later switched to BusyCal, which solved all my problems at the time. A superior product to iCal (Calendar, too) in every way. Not sure what they're up to now. But I got sucked back into Apple in later years, and tried Calendar again. And it did work fine, until this bug cropped up. Very frustrating that Apple abandons older versions, even when they break them (I suspect that the actual problem is within iCloud, probably something Apple changed that orphaned older versions).

Like I posted, Apple does not seem to be able to write legitimate software (regardless if it's for business or not) and can't be trusted to make good on faulty its own product. I realize that's a bit of a bold statement, but it is certainly true in this case, and for all their cloud products for the most part. They've always been flakey.

I suggest we stop trying to "fix" Apple's bugs, and turn to third party solutions instead. That worked for me before. It's worth another try this time, too... I'm going to revisit BusyCal and see how they're doing...

updated today to 10.10.5 yosemite and problem resolved.  i did not want yosemite, but this bug was about as stupid as having to update to fix it.  so, i figured with the captain coming next to bite the apple bullet.  now if i could just turn off this stupid game center on my iPhone....   apple is getting to be too much
