I lost my calendar data

All of a sudden, my calendar data disappeared. About a week after installing Mountain Lion. Nothing else to say...
Any ideas?

Have you ever made a backup or Export your calendar archieve?
If you go to File, Export -> Calendar Archieve
you can save files whenever you feel like.
Or, do you have a compete Time Machines backup?

  • I lost my calendar data with Yosemite 10.10.2

    MacBook Air (late 2010) with installed OWC 480 gig SSD hard drive. Updated to Yosemite 10.10.2
    Only my calendar data lost. My husband's data is fine both for office and home. My new data is now in a file called 'Calendar' which I did not create. Old file was AMWhome. I changed the name from 'home' a year or so ago in order to differentiate from my husband's home file.
    Restoring data to the newly named 'Calendar' brings back the AMWhome name and data for about 3 seconds and then it is gone! I found these files in the trash.
    I have my data on another machine (MacBook Pro) which I took off-line and copied the data file. I tried to restore the data from the file from the MacBook Pro with the same result, the AMWhome appears and the data appears for about 3 seconds and is gone.
    So, now what can I do?
    I cannot empty the trash on my MacBook Air and cannot go online with my MacBook Pro.
    Help!
    Thank you,
    Adele Ward

    1. Are you positive you looked at the correct backup IPD file. If it was backed up during the upgrade, it would be named something like "loader backup**todays date**.ipd"
    They are normally saved to the My Documents folder.
    2. Do you sync to Outlook or any application on your PC?

  • I have lost my calendar data and am having a hard time retrieving it from Time Capsule. Can anyone help? I am using Mountain lion OS

    I have lost my iCal data and am having a hard time retrieving it from Time Capsule. I am using Mountain Lion OS om iMac. Can anyone help?

    You cannot see it because it is hidden.. one of those great things apple does.. if it is hidden in your Mac then it will be hidden in the Time Machine Backup.
    You will need to restore the entire folder to a different location.. and unhide it.
    There is some info here about restoring particular files or folders.
    http://pondini.org/TM/16.html
    And some info from Lion which should also relate to Mountain Lion.
    https://discussions.apple.com/thread/3231381?start=0&tstart=0
    There is stuff about recovery near the end.
    One wonders sometimes when Apple make these decisions if they ever think about what happens when something goes wrong. Hiding files..???

  • IOS 6 "lost" my calendar data

    When I updated my iPad to the new OS all the data on my calendar from previous months disappeared! I was keeping track of some important information and now it is gone. I am not able to reconstruct some of this data. Where did it go and can I retrieve it somehow? Please help!

    I had the same problem with my iphone 4S, but I don't have a menu item BKesley4 mentioned. My solution was:
    To sync your calendars using iTunes:
    With iTunes open, connect your iPhone or iPod to your computer.
    Click the Info tab (or the Contacts tab)
    Click on Sync Calendars checkbox if it's not checked in
    Uncheck "Do not sync events older than x days"
    Click Apply

  • I lost my calendar data when upgrading from OS 8 to new OS 10

    The OS upgrade worked fine.  Upon opening iCal in new Mountain Lion, I don't find any of my calendar entries from before the OS upgrade.

    I have the same problem migrating from a G4 iMac running 10.4 to an intel iMac running 10.6. Cannot even import calendar files exported from the old machine. Help!

  • Lost all calendar data when upgrading from 10.4.11 to 10.6.1

    So I bought the "MacOS X Boxed Set" for SNow Leopard, and installed it over my former 10.4.11 install on the main drive of my Intel-based iMac. Everything seems to have made the transition just fine -- my desktop icons, my emails, my dock, etc. Except for iCal. I open it and it's blank! Why? How do I restore all the recurring events and such that were in iCal previously?

  • Recovery of Calendar data lost when Merging with iCloud

    I Was wondering if anyone could help.
    Basically, I have somehow managed to wipe ALL the entries from my partners iPhone 5c calendar when turning calendars on for iCloud. When prompted I pressed the merge calendars button and then everything disappeared. I turned iCloud calendars off again and the calendar which was called something like "on my iphone" has disappeared.
    I downloaded some 3rd party software which scanned the phone and found the calendar entries, but to restore them would cost my £55 for the full version of the software. Is there a way to access this data and restore it without spending this sort of money?
    Just to complicate matters, a backup of her phone hasn't been done since the start of june, roughly 7 weeks ago. I'm concerned that if I restore from that backup she'll lose contacts she's added since there along with saves and other updates she's made to apps on her phone, which will put me in even more trouble than I'm in already. I'm guessing the phone hasn't been synced with iTunes since this backup was made, although I have transferred recent purchases.
    So, is there a way to recover the calendar data that has disappeared without losing anything else?
    Thanks for for your help

    Hi
    No I hadn't created a Calendar Archive before this mishap (I will now), and I thought it would be covered by the Time Machine Backup.   I was activating my iCloud drive for the first time and I think that it was doing this that somehow lost the calendar data. Previously the Calendar data was on the Mac hard drive.
    I have now managed to get the old calendar back, but I don't quite know how.
    The links to calendar backup in your reply led me to tinker more with the Time Machine, and the data on the My Passport drive directly. I could not see the any calendar directly in Finder or Time Machine, but a Finder search on My Passport's latest backup showed various calendar stuff, including .ics files, in [users/myname/library] which were hidden.
    I either restored one of these, or imported one via Calendar. I tried both, but neither seemed to work at the time. However, I reopened Calendar a some time later and found that the “lost” calendar had returned.
    I couldn't find a way of revealing hidden files in the preferences, and I think that the library containing the Calendar files must be hidden because I could only see them via “search”.
    Anyway, all's well that ends well, but I wish that I really knew how I fixed it. Thanks for your help.

  • RECOVERY OF CALENDAR DATA

    I have a Macbook Air operating on Yosemite 10.10.1.
    I have just inadvertently lost all of my Calendar data by activating  the iCloud Drive and then realising that I didn't want to put the Calendar on it and deselecting this on the iCloud Preferences.
    It did come up with a message saying that all data on he drive would be deleted from the Mac, but I didn't think that I had put anything on it at that stage.
    I would like to recover the Calendar.  I have back-up on a Passport-for-Mac using Time Machine, but cannot identify where the "old" Calendar data file is.
    Can anybody help please?

  • Calendar data recovery.

    iPhone calendar was inadvertantly set to NOT keep track of events more than 30-days old.  After 2  months of losing calendar items this was corrected.  If their any way to recover the lost calendar items?

  • HELP - I've lost all my Calendar data, most of my Notes, and other issues

    In priority order:
    1.  Sometime in the last two days my iPhone 4S, with IOS 7.0.4, lost all my Calendar data except birthdays from Contacts.
    2.  Most of my Notes are lost except those from PC.
         WRT the above, iPad data is still intact.  
    3.  IOS 7.0.4 crashes apps A LOT! Even Apple apps.
    4.  IOS 7.0.4 is slow.

    Resolved items 1 & 2 by rebooting the phone.  I am happy that it resolved, but it shouldn't have happened n the first place.

  • How do I retrieve lost calendar data?

    I didn't like having both personal and work calendar in both devices (iPhone and iPad) and decided to deactivate iCloud calendar feature and lost all the data.  How can I get them back to my devices again?

    I would try reconnecting to iCloud, and wait until your calendar appointments re-sync. You may have to go to the settings pane and set the calendar settings to re-sync all old appointments – I think the default is to only sync appointments that occurred within the past month and in the future. After all your appointments reappear, then go to the settings pane and choose "Mail, contacts, calendars". On the next page select your MobileMe account and you will see switches that allow you to turn off contacts, mail, calendars etc. turn off the calendars and it should ask you if you want to keep the events or not at that point tell it you wish to keep the events.

  • HT4901 By synching our computer and tablet together with our new iphone, we lost all our critical calendar data. How do we get it back?

    By synching our computer and tablet together with our new iphone, we lost all our critical calendar data. How do we get it back? The help info, HT4901, was the closest info from the Help pages but it assumed we were already on icloud and had simply disconnected our calendar from icloud. Actually, we were simply trying to synch our devices by signing up with icloud for the first time, so it seems our calendar never had a chance to get uploaded. In any case, how do you reconnect / re-access a calendar on icloud?

    If your calendar does not appear on icloud.com it never uploaded to iCloud.  If it is no longer on your computer you would have to restore it from a backup source such as Time Machine to restore it.
