IPhone 4 problems syncing with iCal in Lion

I have an iPhone 4 with IOS 5.0.1, and a Macbook Pro with OS 10.7.2 and itunes 10.5.1. Every time I plug my iphone into the Macbook, it launches itunes and does a sync, but then it gives me a "Sync Conflict" message. It tells me there are 2 conflicts, and these are always the same two Ical items which i have recently changed on my iphone. It asks me how I want to resolve them, and when I click on "using iPhone" and then OK, the message goes away, but the sync does not work and the message pops up again every 5 minutes. I've tried using the iCal items, same problem.
One detail: About a month ago, i had a brief stint where I tried using ICloud, but I found that all of my ical events were doubled and even tripled and it was a huge mess. I kept having to delete events that were repeated, and they kept coming back. I deleted iCloud and stoped using it. Not sure if this is relevant.
Another detail, I just switched to Lion about a week ago, I was using OS 10.6 before and never had this problem. Seriously considering uninstalling Lion.

Hey,
I have the same issue only I went from a widows 7 OS to a Vista OS to backup mine.
This seems to be a common fault since the new update of 4.3.3, as there are several people who have done the same as you and I but on several windows OS.
Therefore one can conclude its not a fault with windows but may lie in the iPhone update.
Also I have seen a patten in that its the personal computers of the iPhone owner that wont work, yet someone else's system with work just fine?
Still hopefully there is more to come to resolve this issue.

Ical on iphone does not sync with ical on mac, but the mac does it!

My ical on my iphone does not sync with ical on mac using MobileMe, but reverse it works very well.
so typing an new event in ical on my phone will NOT appear in ical at my computer. Typing a new event on my mac, than within 10 seconds it appears on my phone.
anybody know how to resolve this? never had the problem before
problem 2: ical on my iphone seems to duplicate a lot of events. Non of them are duplicated on my computer.
related problem?
thank
Hein

I have solved my problem - don't know if yours is the same. I noticed on iPhone, when I listed the calendars there are two sections: the top line showed "All Calendars ->"; when I click on that I get duplicate entries for everything.
Below that is:
"From My Mac.
"All from My Mac ->", followed by a list of individual calendars. When I clicked on that I got single entries.
This led me to realize that in my Settings ->Accounts I had the old "...mac.com" a/c and new "..me.com" a/c. I had thought it didn't matter.
Once I eliminated the "mac.com" A/c, I had only one set of calendars.
Hope this helps you.

With Update 1.1.3 iPhone no longer syncs with iCal

I run Leopard on a MacBook Pro. After upgrading my iPhone to 1.1.3, iCal and the calendar on iPhone no longer syncs, at all. I brought this to the NYC Soho Apple Store, but the genius couldn't figure it out. Only the two default calendars "Home" and "Work" synced, although not every time. Help! What should I do now? Enter events twice? Once in the iPhone, since that's what I take with me, and once on iCal, since when restoring iPhone settings that's what's used? Many thanks!

I'm not sure I understand what the problem is -- first you said it doesn't sync at all, and then you said that your Home and Work calendars sync intermittently.
Personally, I would do several things:
1) Make sure you are not using Entourage -- and if you are, make sure all Sync functions are unchecked in preferences so that nothing is using Mac's sync services and copying back and forth.
2) Print out your calendars (use month view) for the entire year so that you have a backup.
3) Do you need to have separate calendars? I find it ridiculous personally to have work and home and entourage calendars, and combine them into one. It's all my calendar information anyway, and it goes with me everywhere, why would I want more than one calendar....anyway....not to get off on a tangent...
If you can do without two calendars, combine them all into one (you export one of them, then import it back into the other one, then delete the one your exported and imported. You can do a search for the help topic on how to combine calendars.
Rename the one combined calendar your name, rather than home or work. Sync your iPhone. On the Info tab, make sure that you have the calendar name selected (it will recognize the new name of your calendar. Also make sure you have the sync to: Your Name calendar selected.
4) If that does not work, I would totally delete all of my calendars from iCal - and sync (to erase all the calendar information from your iPhone).
5) Create a new calendar, and manually re-enter all your calendar information. Sync new information to your iPhone.
In reality -- I have no idea why you are having problems -- I also have 1.1.3 on my iPhone, and I also sync with iCal. I haven't had any problems -- but then I only have the one calendar.

IPhone will not sync with iCal

I'm having problems whereby events created on my iPhone is not syncing with my iCal. (Entry does not show up on iCal after sync)

archonium,
did you check the sync iCal option in the iTunes (iPhone) sync tab?
If you did and that doesn't work. Try this....
1) Open Disk Utilities on your mac and run 'Repair Disk Permissions' on your hard drive
2) Restart your mac.
3) try again. If it still doesn't work, try resettin the iPhone. Try again.
4) If the above doesn't work. Try RESTORING your iPhone via iTunes. That may work.
hope one of these work
good luck!

Events added on my iPhone are not syncing with iCal. ios5 and Lion

I always have my iPhone handy and use it all the time to add my events. I think it is easier to add them on the phone and easier to view on my MacBook Pro. Anyway......... all the events I am adding on my iPhone stopped syncing to my iCal as soon as I installed ios5. Is there a fix yet? It is VERY annoying!!!

i figured it out.... before syncing your phone to your macbook or whatever:
-go into settings
-select icloud
-go to calendars
-change the selector from ON to OFF
-sync phone to computer
-ical syncing with phone will now work like it did before iOS5 and iCloud, but in a good way

Outlook not syncing with iCal after Lion Upgrade

I updated to Lion, so I could more easily sync our family's calendars and contacts in Outlook to our iPhones/iPods via iCloud. Now that I have done that, Outlook no longer syncs to iCal/Address Book and then there is the internal Microsoft issue. How do I get the syncing working since iSync isn't part of Lion?

Greetings,
You may have issues with Outlook and might want to remove and reinstall it (http://support.microsoft.com/kb/2398768).
Before going down that road:
Backup your computer Addressbook: http://docs.info.apple.com/article.html?path=AddressBook/4.0/en/ad961.html
Backup your computer iCal: http://support.apple.com/kb/HT2966
Backup your entire computer (its a good idea): http://support.apple.com/kb/HT1427
Quit all open applications
Follow all the steps in this Microsoft article: http://support.microsoft.com/kb/2452489
If syncing is still not working:
Quit all open applications
Follow http://support.apple.com/kb/TS1627
If syncing is still not working:
SafeBoot the computer: http://support.apple.com/kb/HT1455
While in SafeBoot remove the following to the trash:
Macintosh HD > Library > Caches (All the contents of the folder not the folder itself)
Home > Library > Application Support > Sync Services (The entire folder)NOTE: To get to "Home > Library" in Lion: Click anywhere on the desktop and then click on the "Go" menu at the top of the computer screen while holding down the "option" key on the keyboard. You will see "Library" in the menu.
Restart the computer and test.
Hope that helps!

Events doubling up on iPhone 3G when synced with iCal on my iMac

Hi all,
I'm having an annoying problem with iCal on my iPhone 3G...
I'm happily using iCal on my iMac and everything seems up to date, days and events look perfectly normal on there. However, when I sync it up with my iPhone 3G, for some reason some events (but not all) are being doubled up on my iPhone. They aren't there on my iMac's copy of iCal - that still looks correct.
I tried going through and deleting the extra events from my iPhone. As soon as I synced again with my iMac, all the rogue events reappeared on my iPhone. Tried it a few times, same result.
I have a feeling the rogue events that are appearing on my iPhone are ones that I originally inputted onto my iPhone's copy of iCal, then a few weeks later I've adjusted them, deleted them, generally tidied up my calendar through iCal on my iMac. This might be why it's only doing it to a few events I've added, not all of them. When I re-sync, it's like they keep being resurrected on my iPhone.
I've tried re-syncing using the Advanced option in iTunes where you replace information on the iPhone - the rogue events still came back on my iPhone. I also just tried going to my iSync preferences and resetting my Sync History. Didn't fix it.
I don't use MobileMe and I have no other computers or calendars so there's nothing else trying to sync up that might be generating these doubled up events. I'm not doing anything other than try and sync my iPhone 3G with my iMac through iTunes.
Any ideas where these extra events are coming from and how I can flush them out of my iPhone's copy of iCal?

I just posted this in another thread, but I'll summarize it here for you:
I had three groups of calendars in the Calendar app on my iPhone (OS 3.0): calendars from my MobileMe account, a set of calendars I had subscribed to with iCal, and calendars entitled "From My Mac" which was a duplicate of every calendar from the other two groups. What I wanted was to go back to having just the MobileMe syncing over the air, plus the subscribed calendars, so everything would be continuously updated instantly. I didn't need a duplicate set of static calendars, and so I wanted to get rid of the calendars in the group "From My Mac".
I made sure I'd unchecked the checkboxes for iCal in the Info tab of iTunes for my iPhone, and then applied the sync. Unfortunately, this did not remove that new special group of calendars for my iPhone, yet. I guess it kept them just in case. (Side note: Interestingly, when I recreated my problem to re-test this, I forgot to do this again. The checkbox for the Calendars seems to magically uncheck itself if I go through the rest of the steps without doing this first. I think iTunes gets informed from the cloud at some point, perhaps after I decide to delete the calendars in the "From My Mac" group from within the iPhone. So, you may not need to do this. Anyways, make sure it's unchecked so it won't happen again…)
On the iPhone, I opened the Settings app, went into "Mail, Contacts, Calendars", chose my MobileMe account, and then turned off the Calendars. It asked me whether I wanted to delete the MobileMe calendars from my iPhone and I chose "Delete from My iPhone". Note that the message explicitly refers to your iPhone and not MobileMe, so you are not deleting them from MobileMe. (But please do read the messages and don't assume that's what it says. There are many prompts.) If you don't delete them for your iPhone, they'll get added to the "From My Mac" group of calendars. This isn't a problem since this group will get deleted later, so you can choose either to keep them, or delete them now.
Wait a moment before turning the Calendars back on, to give it time to process the "offing". When turning the Calendars on, I was asked whether I wanted to merge the MobileMe calendars with the existing calendars on my iPhone, that special group I was trying to get rid of. I chose "Do not Merge" because I didn't want even more duplicates, I just wanted what I had in the cloud, on MobileMe.
After not merging the calendars, next it asked whether I wanted to keep the existing calendars I had on my iPhone. I chose to "Delete" them, which it then asked me to confirm (Delete or Cancel) so again I chose "Delete". (And once again, please read the messages carefully and don't assume what they say just because what is written here. The messages might change with updates.) When I opened the Calendars app on the iPhone, the "From My Mac" group of calendars was completely gone. I was back to what I had before, just two groups: the MobileMe calendars I had just turned on, and the subscribed calendars that I hadn't touched.
I think the key is to not merge with the duplicate set of calendars, and to not keep them. Otherwise, you can't go wrong because everything is on MobileMe, as long as you're synced with it.

Iphone does not sync with Ical

When I add an item in Ical it always appears on my Iphone after a sync. However, if I add a calendar item on my Iphone and then sync it never appears in Ical. I have looked at the settings 100 times and no matter what I do I cannot get this to work properly.
Anyone have any ideas?
Thanks

If resetting sync history doesn't work for you (it didn't for me), you can try the following. This solution, although lousy, seemed to work. Make sure you have auto-sync selected from iTunes. Reboot with your iphone plugged in. When you log in, do not open any of the applications required by iTunes to sync. I got my contacts and my calendar items. Finally. Now if Apple could fix this in the next update, we'll all be set.

My ical on iphone will not sync with ical on macbook

I have iphone 4s and Macbook Pro (OS X Lion; version 10.7.5)
I have my iCloud all set up on both my iphone and my macbook. I am trying to sync my calendar to when I enter in a new appointment on my iphone calendar, it will also add to my macbook calendar.
I have checked for all system updates on both machines, rebooted everything, and nothing seems to work.
My ical on my macbook will sync to my phone, but I can't get it to sync the other way.
Any help or advice?
Greatly appreciated!

Welcome to the Apple Community.
First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings.

Problems syncing with iCal and Treo 650

I use iSync for syncing my iBook G4, .Mac, iPod Photo and Treo 650. It has worked fine until a month ago. The iSync conduit somehow works OK with the Contacts/Address Book, but doesn't for the Tasks and Calendar (iCal). It is a real pain the to write everything manually on the Treo and the iBook separately. Can anyone help me with this? I really don't want to replace (reset) all the info on my Treo; this will cause me to re-categorize everything in the Treo, for iSync doesn't take care of it as far as I know. Thanks, ~L
iBook G4 Mac OS X (10.4.7)

Welcome to Apple Discussions.
What does your HotSync log say about these unsuccessful attempts to synchronize your Treo 650?
While it is important to correct this problem, if you want support for categories, calendar colors, contact photographs or icons, extended electronic mail addresses, URL and birthday data, you should ditch iSync in favor of the Missing Sync for Palm OS, a much more powerful and reliable program:
http://www.markspace.com/missingsync_palmos.php
On advanced Palm organizers and smartphones like your Treo 650, extended support is available as outlined in this document, for contacts…
http://www.markspace.com/support/kb.php?x=&mod_id=2&id=2560
…and this document, for events and tasks:
http://www.markspace.com/support/kb.php?x=&mod_id=2&id=2563
In addition, it supports internet sharing, Finder mounting and file transfer with SD cards, conduit profiles, iPhoto and iTunes media file synchronization, the synchronization of AvantGo content, and network synchronization of supported devices.

IPhone no longer syncing with iCal since purchasing new Macbook Pro

I've searched other posts and some were exhaustively long complaints about iCloud and I really don't want to read through 600 posts to get to what should be a simple answer to a really obnoxious problem that never used to be a problem before Maverick.
My calendars are not syncing. I've gathered from 1 other post to make sure that I have iCloud turn on for iCal on my Macbook and on my iPhone. Done. But still nothing is syncing. When I sync on iTunes, no calendar syncing happens. How else am I supposed to sync my calendars? Please help!

You can no longer sync via iTunes. That method of sync was removed (and the 1000+ post thread is arguments over things tangientally related to that).
You need to sync via other means than iTunes, then.
One option is to use iCloud. If you sign into iCloud on all your devices, and then make sure your calendars are in the "iCloud" section on your devices, they should sync.
If you don't want to use iCloud, you could use Google calendars, they operate much the same way (but may be less reliable).
Or if you use Exchange for work, you could sync that way.
Or if none of those are acceptable, you could install OS X Server and set up the calendar server on your local network and use it to sync. This is fairly straightforward "for setting up a UNIX calendar server" but it's not trivial and beyond the scope of a forum post to explain it all

Hi All: My iPhone will not sync with iCal.

This is a direct USB connection, no MobileMe involved. There is no error message; the Mac apparently just does not "see" events on the iPhone. I've changed the synching prefs from "Sync all calendars," to "Sync selected calendars" (and checking all of my calendars), back to "Sync all calendars"--and the iPhone info simply does not show on the desktop Calendar.
I added this question to the John Maisey thread, but got no responses. Any ideas?
System info:
Mac OS 10.6.7
iTunes 10
iOS 4.3.3
Mac Pro 2.66 GHz Quad-Core Intel Xeon

Hi,
I suggest you reset your sync history, then sync through iTunes again. See http://support.apple.com/kb/TS1627
Post back if that does not work.
Best wishes

Why won't iPhone sync with iCal?

Since downloading the most recent iPhone software update on Mon. 10/1/07, my iPhone won't sync with iCal on my MacBook. I get a "mingling data" error, and that's odd because the appointments that don't transfer to iPhone can be clearly listed in iCal. What happened with this latest update to create this?
Thanx!
MiclHer

Actually, my question is answered by myandrews response to Carl Jonsson's same problem dated Sep. 28, 2007.
Thanx,

IPhone Calendar not syncing correctly with iCal since Lion-install

Since installing Lion, the calendar on my iPhone is not syncing correctly:
Events created on my iPhone don't show on my Mac
Events edited on my iPhone don't change on my Mac
Events that I created in iCal on my Mac, for test-purposes, and then deleted immediately, show up on the iPhone when syncing.
Syncing through iTunes (not MobileMe).
Using WeekCal on my iPone, but it seems that the same is the case with the "original" calendar-app.
No similar experience prior to Lion-install.
iPhone is iOS 4.3.4 -up to date
Any ideas? Does anybody know how to reset the sync, for instance?

Hi, my name is Lucas, i'm an Apple Certified Technitian.
Last couple of weeks i've installed OSX Lion in a few Macs.
But one of them drove me crazy!
I have a Late 2007 White Macbook and i installed OSX Lion last week. I also have an iPhone 4 (Factory Unlocked) that i also updated to IOS 4.3.5 ... no problems syncing between them
Then i did the same with a 13'' Unibody MacBook Pro and an iPhone 4 (not unlocked)... no problems neither
Yesterday i installed Lion on a Mid2010 15" MacBook Pro and updated another iPhone 4 (Factory Unlocked) to IOS 4.3.5 and when i tried to sync the iphone with iTunes 10.4 nothing happened.
I mean, nothing.. the iTunes started syncing and when it gets to sync the calendars it stayied there forever.
I left it for hours and nothing.
As i said i'm an ACT so i tried everything.
1- Remove Calendars from iPhone and syncing again
1- Repair Permittions
2- Reinstall iTunes
3- Reset iTunes and iCal Preferences and Caches
4- Backup iCal - erase ical content and generate a new iCal database
5- Reset Syncing Prefs and logs
6- Use DiskWarrior from an external OSX
7- Reset PRAM
Nothing worked.
I thought it could be some conflict with Microsoft Outlook and/or Exchange server since this Mac is the only one of the three macs i installed that uses Outlook Sync and Exchange server and it's the only one that gave me trouble.
But disableing it didn't worked neither.
THE SOLUTION
I Already solved this thing out. But i still don't understand the logic of all this... anyway, what y did is this:
1- turn off microsoft outlook sync with iCal (from outlook preferences)
2- Backed up iCals (Just in case)
3- Create a new Calendar Category (by default you have Work and Home... i created one called Test)
4- i Created a new task at that calendar
5- In iTunes uncheck the "Sync iCal" box and sync the iPhone
6- Check th "Sync iCal" box, then check the "sync the selected calendars" box
7- Check the "Test" calendar and sync the iPhone.
This worked so i started creating task in this Test Calendar both in iphone and mac, just to test it, Worked fine.
Then i selected all the other calendars (Home - Work - etc) and i turned on the outlook sync
Then i synced the iPhone and Voilà everything is working again.
Now i can create task in outlook calendar and when y sync the iphone it appears on it.
I don't know what the problem is... but this looks like the solution
HOpe it works for you!
