Duplicate Calendars showing up

In iCal, I now have two versions of each of my three Calendars showing up: one set under [email protected], and another under MYNAME @me.com. How do I get rid of one or the other?

Read this background thread.
iTunes won't automatically eliminate dupes. It has two options to display them. File > Display Duplicates lists all items with the same Name. When holding down shift (option on a Mac, I think) File > Display Exact Duplicates lists items with the same Name, Track #, Disc #, Artist & Album.
Once displayed you still have to decide which tracks to eliminate. One of the common errors people make is to delete all the files shown whereas you want to keep one of each repeating group. With large numbers of files making these selections is tedious, if not almost impossible. Add that that to the fact that in some cases you need to preserve the file when deleting and in others you will want to discard it (and you can't easily tell which from looking at the information displayed in iTunes) and you can see why it is best to automate the process.
By all means make a suggestion at iTunes Feedback but in the meantime if you want a tool that works I have one for you, for free, and I'm happy to try my best to explain how it works. It's about to get an update which will let you keep the best quality (read largest) version when you have ripped the same tracks in multiple formats/bitrates over time and now want to tidy up.

Why do i have duplicate calendars?

I noticed this morning that I have duplicate calendars showing duplicate events on all of my devices: iMac 2011, MacBook Pro Retina 2014, iPad Air and iPhone 4S. All with latest system updates. Only the calendar for my school events (which I use most actively) shows as duplicated, others remain normal. I followed the instructions on Apple's troubleshooting page: I checked that all relevant services were shown green on their system status page. Then I went to iCloud.com and checked whether on not the calendars and/or events were shown twice there as well. I saw two calendars for my school events by the same name, one with purple color that I remember choosing, and another with blue color that I think is the default color for new calendars, and that which I had not chosen. But check this: The events on iCloud calendars were NOT duplicated, but randomly shared by these two calendars. Meaning some of my school events were purple, some were blue. I have always used only one calendar for my school, the purple one.
Let me recap:
On all my devices: Two school calendars with duplicated events, purple and blue.
On iCloud: Two calendars, purple and blue, but no overlapping school events! Both purple and blue events with no apparent logic afaict.
Now the next step on Apple's page was to contact the telephone support. I submitted a contact request, and after a short while an american lady called me and we started trying to sort things out. I tried my best to explain to her my situation, but perhaps because things were quite complicated, and English not being my native language she might not had understood everything. She asked me if I had tried to delete one of the duplicates. No I had not, because even though on my devices the events were shown twice, on iCloud they WEREN'T, and I didn't want to take the risk of losing anything. I think it was at the moment I was explaining this to her when the line dropped, and she never called back.
Having given up on tech support I decided to try fix this on my on and went back to iCloud. I thought if I change all blue events to purple and then delete the blue calendar, I might not lose any events. So I double-click on a blue event, change the calendar back to the original purple and hit ok. I get an error saying "Couldn't save changes to [event's name]. Your changes to this event couldn't be saved because of a server error. Please try again." I report and hit ok. The event is still blue. I double-click it and try to change the event's calendar again. This time I get an error "Couldn't save changes to [event's name]. Your changes to this event couldn't be saved because it was just deleted by another device." I hit ok, and NOW I see two of the same event, one in blue and one in purple. Well at least the event is now supposedly where it should be. I repeat this annoying procedure to all blue events. Then I try to delete the wicked blue calendar, praying I won't lose anything important. Of course I get an error: "Couldn't save changes to [calendar's name]. Your changes to this calendar couldn't be saved because it was just updated by another device." So I go and try again, it worked for the events. And this time the calendar is gone!
But wait. The events of the purple calendar are now duplicated. So I only got rid of the calendar clone, but I still have events shown twice.
I'm getting way too tired to work on this any futher. Why is iCloud acting like this?

Highlight a song. Press command+r to reveal the song in Finder. Do that for the duplicate. Are they in the same location? You can also check this by getting info on a file and checking its location in the summary info, then check for the other file.
If you have a file in a folder that itunes doesn't control and then add the file to itunes it will place a cpy in the itunes folder when you add the file, leaving the original. Not sure how you ended up with two in itunes but I'd need to know the details of your preference settings.
I don't know about the rest. I have never bought music from ITMS.

How do I get rid of duplicate calendar entries in my notifications?

I managed to get rid of all my duplicate calendar entries on my calendar. I unchecked all but the two calendars I use.
The problem is that when I go to my notifications screen, under "Calendar", it still shows all my entries like three times. How do I get rid of this? It takes up all the realestate on my notifications.

Sounds like your syncing Calendars over the air with iCloud, as well as with a supported Calendar application on your computer. Doing both will duplicate your entries, so do one or the other, not both.

Contacts and calendar showing double - because of MobileMe?

I got mobile me and the contacts and calendar updated wirelessly as expected, however the last time I plugged in my iPhone to my computer, the iPhone synced with all information (contacts, calendar, itunes, photos, etc.) and now both my contacts and calendars are showing double on my iPhone. Is there a way to fix this?
the calendars show two boxes on my iPhone: "From my Mac" and another "(email)(Mobile Me)". I assume this is why there are duplicates, however I do not know how to delete or get rid of it. I thought Mobile Me would simply update information from the Mac, not add to it.
The contacts have the same two boxes and show all my groups of contacts twice.
Am I not supposed to sync with my mac now that I have mobile me? How do I get rid of these duplicates now?
Thank you,
Kim

Duplicate calendar entries after switching to z10, need to clear my local calendar

Hi,
While transferring my data from a bold 9900 to my new z10 using BB Link I ended up with duplicate calendar entries, one from my account calendar and another from my local. Some of the entries don't show up as reoccurring so it's difficult to remove. How do I clear all the local entries? I tried searching and only found solutions for the previous versions of the desktop software.
Thank you,

Hey z10bbuser,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
You can not clear individual databases in BlackBerry 10. You can clear the calendar individually by manual deletion or you can do a security wipe. This is found under Settings>Security & Privacy. Please Note: A Security wipe will erase all data and installed applications on the BlackBerry Z10.
Let me know if you have any more questions.
Cheers.

Duplicate calendar entries - but not related to any kind of sync

I went on holiday for 3 weeks and during that time my iPod touch discharged completely. When I came back and charged it up again I saw that it had reset its date back to what I presume is the factory default of 01 January 1970. I set the date and time to the current date and time - and then discovered that all my MONTHLY and YEARLY repeating calendar entries (but not the WEEKLY ones) have all been duplicated. This is not the result of any kind of sync up since (following a complete system rebuild following a virus attack) I have not yet reinstalled iTunes on my PC and I have not knowingly synced with Outlook because I almost never use it. If I delete an entry that has been duplicated then BOTH entries are deleted. Has anyone seen this behaviour and can tell me how I can remove the duplicate entries? I have looked for posts relating to duplicate calendar entries but they all deal with syncing-related problems whereas mine is not. Thanks.

I have a similar issue. I bought an ipod touch last week and today I synced my entourage contacts, and address book. The address book entries are fine, but I have duplicates on my calendar. Now, its not duplicating per day, its duplicating the previous or next day. For instance, I have a birthday listed for today, it will also show for yesterday or tomorrow. What is causing this? I've checked the calendar on entourage and ical and both show correctly. (ical copies items from entourage)

Cannot push back new calendar events to Mac, duplicate calendars, more...

I'm having tons of issues with iCal and my iPhone since 2.1. New events entered on my iPhone show up in MobileMe online, but not on my Mac, ever. Duplicate calendars are starting to show up in my iPhone, and now NONE of my calendars are showing up in MobileMe (all my events are still there though). What gives Apple?

Apple, have you even read this post? MobileMe/iPhone service is terrible, simply awful. New events in my laptop calendar sometimes don't show up on my iPhone, or from my iPhone to my laptop, events are showing up twice other times, calendars are being duplicated, this is a total mess. I need this calendar to keep track of meetings and appointments, and at this rate, I simply cannot trust the iPhone to do this right.
I remember when Apple products "Just Worked". Now, they simply don't work well at all.

Multiple duplicate calendars

Hey - can anyone help! I’m going crazy here!
I have a G5, and iPhone and an iPad and I’ve been all day trying to sort out a syncing problem. I followed all the Knowledgebase articles, and even chatted to an Apple MobileMe expert - so now I need to turn to the Apple community for help!
When MobileMe (MM from here on) syncs with iPad and iPhone I get six copies of each calendar, although iCal on my Mac only has one of each.
I’ve tried deleting all the calendars, trashing caches and pref files, deleting and reinstating MM accounts on the iPad.
Address Book however sync’s fine - all devices show the same data. So why is calendars showing six copies of the same info?
It’s driving me nuts!
Thanx, Andy

Didn't have the duplicate Help menu problem, but in case this helps, here's what worked for me:
1- In the MobileMe preference panel, switch off Synchronize with MobileMe (in the Sync tab) and Sign Out of MobileMe account (Account tab).
2- Restore ~/Library/Calendars folder from Time Machine to the state it was in just prior to installing Snow Leopard.
3- In iCal, delete the duplicate calendars, leaving only the 'correct' one. (Determining which one to keep can be tricky: in my case I deleted the incomplete 'duplicate' calendars, where some appointment entries were missing).
4- In the MobileMe preference panel, sign back into to MobileMe (Account tab) and switch Synchronize with MobileMe: Automatically (in the Sync tab) back on.
5- In the Sync tab of the MobileMe preference panel, click Advanced… at the bottom right. In the resulting sheet, select any existing entry of your newly upgraded Mac's name and click Stop Syncing Computer…, and confirm that you wish to Unregister. (This clears out the old baggage.)
6- Then click Reset Sync Data… bottom left of the sheet, then select Replace: Calendars. The direction of replacement is important: choose to overwrite MobileMe with your computer.
That's how it worked for me. All seems to work nicely now. Note that in the last step, it seems counter-intuitive to me to overwrite a nice, clean MobileMe calendar with the slightly dubious copy, rescued from duplicates, on my Mac. But I could not get the overwrite to work from MobileMe to my Mac. I had to sync from my Mac to MobileMe.
Hope this helps someone… I'm sure there's a cleaner, more elegant way to resolve this problem, but there you go

ICal on iPad: please explain how to use the duplicate calendars

I am traveling with my iPad and cannot get on my computer. I want to add calendar events that will sync to MMe. I have checked off the calendars for @me.com. Sometimes the iPad duplicate switches on. I assume that i have this so i can see if i need to what is really on the iPad ND what is really on mobile me in case i don't have wi fi access. However Apple does not explain to us why so that we could understand our own systems. We are left to guess and stab in the dark. I want to add items that will go over to mobile me and to my phone. Do i add them in to the calendar that is on the ipad and then it will automatically sync the events?
I just edited some items that had previously been synced to mobile me. Those items are showing up synced to my phone so i know they went to mobile me. However i added some new items that went into the calendar on my iPad and those are not syncing (I wonder why apple has this odd system set up?)
So is there something i don't know about entering events in my iPad? Why would there be a dublicTe calendar kept that does not sync to the rest?
Please help! I can't go to my computer to reset hints for now i just have to know how to input events correctly into iPad so they will sync to mobile me and my phone. I have previously fine through resetting hints with mobile me support so it all should be set up correctly.
Thanks

How to delete duplicate calendars on iPod touch?

Hi, I have duplicate calendars that show up in iTunes in the iPod sync prefs and on my iPod touch but that don't show up in iCal. Since they get all transferred to the iPod I have a huge amount of duplicate entries as I cannot deselect just one of them.
How would I go about deleting those entries from the iPod and/or the iPod sync preferences?

I have the same issue on my iPod Touch, but with only a handful of birthdays (not all birthday entries). I've tried removing the birthdays from the contact entries and then putting them back in, but that only removed 1 copy temporarily. When I put the birthday back into the contact entry and sync it shows only 1 date entry, but then after syncing again it goes back to 2 duplicate date entries.

TS4062 Why won't my outlook calendar show data from my iPhone calendar after synching.

Why won't my outlook calendar show data from my iPhone calendar after synching?

I have the same problem - between the issue I had with restoring after the upgrade (Error -48), the duplicate entries I now get between my Outlook appointments and iCloud, and the inability to have Events added from the iPhone sync to Outlook, I'm surprised there hasn't been more outcry about 5.0x! Not to mention the battery problem, which I HOPE they ironed out.

How do I "avoid" duplicate calendar entries on my devices?

I have an iPod touch, an iPhone 4, an iPad 2 and a MacBook Pro running OS X 10.8.2. My software/IOS is up to date on all devices. My main calendar is my Google Calendar. Whenever I sync, my devices show multiple double calendar entries. Now, I have found a large amount of information on removing the duplicate entries which has been helpful. However, I am having difficulty finding an answer as to how to eliminate this in the future. What I want is to be able to go into iCal, on any of my devices, and see the same calendar (which it appears I currently can) without ever having double entries for the same events. How do I need to have it set up? Yes, I have searched ad nauseum; but, I can't find my answer. Maybe I am just incompetent. Any help and/or guidance would be greatly appreciated.

O.K., first, thanks for the response Mistimp. Here is my specific situation, my google calendar is my "main" calendar and is what populates iCal. I hope that makes sense. I want to be able to make calendar entries on any device either in iCal or Google. I believe I can do that. I'll have to check further. If I'm not mistaken, the duplicate entries show up every time I sync. Then, I have to go through the process of turning off a calendar and then re adding it. I want to avoid that step and just avoid duplicate entries forever.

Can I have my work Outlook calendar show up in my personal iCal without my personal entries showing up in iCal?

Can SharePoint calendar show more than 3 items on a Day's schedule in Month view? How?

Hi there,
Can SharePoint calendar show more than 3 items on a Day's schedule in Month view? How?
Thank you so much.

Hi,
From your description, my understanding is that you want to expand all items if a Day’s schedule has more than 3 items.
You could accomplish your requirement with jQuery to auto expand all items when you load month view, please refer to this article:
Auto Expand Month View on SharePoint 2013 Calendar
http://blog.eastridge.net/auto-expand-month-view-on-sharepoint-2013-calendar
If I misunderstand your requirement, please provide more detailed information.

How do I delete a (duplicate) calendar?

I somehow managed to completely duplicate my contacts and calendars from Microsoft Outlook. (I don't use a Mac, or MobilMe or iCal) I don't use the contacts so I deleted them all on my PC within Outlook then synced, but I can't figure out how to get rid of the duplicate calendars.
When I go into Settings - Calendars, this is what I see
From My PC - Calendar
Work (Exchange) - Calendar
They are both the same thing and so whenever I have a calendar reminder, I get the alert twice on my iPod.
Does anyone know how I can get rid of one of these duplicate calendars?
Thanks-
Jenn

I have the exact same issue. The only calendar events that are duplicated are the US Holidays that I subscribed to. This duplication exists only on my iPhone 5S and not my Mac or iPad. I've tried all the other suggestions for removing duplicate calendar events and they don't work. Any ideas?
