iCal Events Gone. Disappeared. Vanished. Erased.

Mine disappeard too a long time ago, and I had even done backups and tried to restore and could not get them to come back! The funny thing is the alarms I have set to send me email reminder still go off even tho' events in cal are not there...it's like a blank calendar! Seems alot of people are having this problem, maybe some day Apple will look into it. I reported in "feedback" area: http://www.apple.com/feedback/ maybe if more report they may fix?
I gave up and got Firefox's "sunbird": http://www.mozilla.org/projects/calendar/releases/sunbird0.9.html#download
..'tho it has alot of things in it, and I've not read how to do all, (yet to find way to have it notify me by email; oh well, it does pop up window alarm)at least nothing has disappeard of of this!

This is exactly what just happened to my imac. I have tried everything I can think of! The events are there - but it will not reset when I delete the cache, when I move the entire calendar events to the desktop, etc.

I had trouble with ical this fall but it seemed to be fixed --- for a while. I called Apple, they put me on hold... for quite a while... and then I was disconnected.

Also -- the mini calender in the corner..shows January 2001 not 2009.

This has just happened to me - on my desktop. Opened iCal and nothing there. Still have data on Mobileme cloud but cannot restore data to my desktop. Added to this the iCal program does not seem to be functioning. Is it possible it has been corrupted? I cannot make a new entry and the program will not quit. I upgraded to 10.5.6 before this happened..... Any known problems?

Help!!

Possible work around. I found on another thread that someone used Time Machine to install an older copy of ical. Apparently the issue is the newest ical update. I tried to use Time Machine to restore but it did not work leaving the existing ical in place. SO... I deleted ical from the application folder, deleted the cache (but not the events/calendar data) from the Library>Calendar folder under my account, and I deleted the ical plist file. THEN I used Time Machine to reinstall the previous version (I went to December 27th) and it all came back, all events, calendars, etc.!!

So --Apple really needs to address this. Apple - if you are listening, please do not release buggy updates, that is oh so PC.

sounds good, but I'm on 10.4 mac and time machine doesn't run on this

I did the same thing - at least 3 or 4 times already - but right now my Time Machine is dead, the drive died just a couple of days ago and my other 2 backup drives are not Time machine drives - so I can't get this back!!

This is so BAD. And I can't get the iPhone to synch with iCal now!

Well I solved he problem. It took me 3 hours. I deleted ALL iCal files from the system including all the reference files and in all he preference folders in the various users and libraries. Then I found an old copy of all the iCal stuff on a small USB drive (not bootable,not time machine- Carbon Copy Cloner) backup I happen to occasionally make as a spare backup of the system, that wasn't much more than a week old, and I copied ALL the icall files back from that drive,; then rebooted the system, Finally it seemed to recognize these old iCal files as the "new" iCal and I am back in business, I just have to fix and update all the entries by hand. It's fortunate I'm a nut and I actually back up my main system at least 5 different ways! I lost 3 backups at the same time!
Meanwhile here was the quote fromMacprofessionals to fix it:
Good Morning Dr. Spitzer,

There are a few options we can do...

I can have one of the tech's call you, to see if we can resolve this over the phone. Or I can have him go on site to your location. You can also bring in your machine and we can take a look at it here at $105 hour.

If you choose to have a Tech come out to you it is $145 hour time starts when the technician leaves the office and is a minimum of one hour.

For phone support it is also $145 at 15 minute intervals.

Please let me know how you would like to proceed

Thank you
Cristal
So my repair job was worth $450 by their billing - what Apple cost me. And it would have been more if I billed my lost professional time. We need to start posting these equivalent $ values to these glithes so everyone including the companies starts to get a sense of the value of these bugs and errors to the customers. There have been many systems where I have spent 10 times the price of the computer working on glitches to get the system to do what I need it to do.

But there is a klugey gruesome work around for now, until Apple ever decides to think this might really be a problem to be fixed. Or will they call a bug a feature and charge for it?

I am using iCal because it synchs with the Palm and iPhone - but if you keep a relatively recent copy, it seems you can "restore" it if necessary, as mentioned in my and other notes. Hopefully this bug will get fixed.

After 30+ years of dealing with computers, I have learned to keep an average of 4 -5 backups of all critical systems and files, with at least one less than 24 hours old at all times.
