ICal won't sync between Leopard & Tiger computers

So, I'm loving Leopard on my Intel iMac and iBook, however the work cpu is still on Tiger for technical reasons.
Problem: My iCal on the home computers doesn't sync with my work machine..... Am I doing something wrong (do I need to reset something), or is this a 'known' issue?
I appreciate any info... (i'm having a tough time syncing my home/personal calendars! :))

I found the solution last night -- and it involved resetting the sync data. I thought that I had already done this by resetting the sync data in the iSync application, but that was the wrong place.
Here's what you should do:
First decide which computer has your "master" calendar. For me that was the one with 10.4.11 on it, as I could get my 10.5.1 calendar events onto the 10.4.11 computer, but not vice-versa.
Second, from the "master" computer, open up the .Mac preference pane, click on the "Advanced" tab, and then click "Reset Sync Data."
When given the option, make sure that you use the data on your computer to replace the data on .Mac.
Third, go to the 10.5.1 computer, and do the same thing (note that the .Mac pref pane is organized a bit differently).
This time, make the sync direction go the other way -- from .Mac back to your 10.5.1 computer.
Note that after clicking the "resent sync data" button, you are offered an option to limit things to just the calendars (excluding things like contacts, keychains, etc.). I recommend doing that.
Note also that you might want to export the database from iCal (and/or Address Book) before doing this -- you can do that from the "File" menu in both apps -- it's just a good back-up strategy in case disaster strikes.
That's it -- for me, everything synced properly between computers after doing these things.
Note that there is an Apple Support Document I also found on this topic that spurred me to try this: http://docs.info.apple.com/article.html?artnum=301378
Good luck,
-Barry

Is there a setting on the iphone that will allow ical entries on the iphone to sink to my other computers
Thank-you

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.

ICal won't sync between computers / iphones

Since I started my free trial with mobileme, I have been trying to synch calendars between two desktop computers and two iPhones. No luck.
I have established a number of calendars on my me.com account, using my iMac. I also share these calendars with only those people I invite. I can see these calendars on the iCal on my iMac, but I cannot see these calendars on my MacBook Pro iCal. When I open an email on my MacBook Pro, alerting me to the Mobile Me calendar, I cannot join that calendar: "You can't join calendars you're sharing."
So how can I get all of the calendars to sync between both computers? If I resolve that problem, maybe the iPhone sync will resolve itself.

I got some help from MobileMe Support. Here's how they solved the problem.
On the laptop, open iCal and click the word iCal at top of the screen. Choose Preferences. 2. Click Accounts. 3. Click the plus button at the bottom of the page. 4. From the "Account Type," please choose "CalDAV." Enter your full MobileMe email address, including the @me.com suffix. If you don't include @me.com, the setup will not be successful. 5. Enter your MobileMe password. 6. For the Server address, please enter: cal.me.com 6. Click the Create button.

ICal won't sync between iPhone and iPad

My iCal will not sync from my iPad to my iPhone.

If new events added to the calendar on your phone do not appear on your calendar on icloud.com, go to Settings>Mail,Contacts,Calendars>Default Calendar on your phone and be sure you have selected an iCloud calendar as your default and not something else like On My iPhone, a Gmail or Yahoo calendar, etc. If you haven't, make this change, then add a new event and see if it appears on your calendar on icloud.com now.
If your settings are correct and new events still aren't appearing on icloud.com, add any missing calendar events from your phone to your calendar on icloud.com. Once the calendar on icloud.com is up to date, go to Settings>iCloud, turn Calendars to Off, choose Delete from My iPhone when prompted (they will still be in iCloud), then after a minute or so, turn Calendars back to On. Then add a new event on your phone and see if it appears on your calendar on icloud.com and your iPad now.

Ical won't sync between two computers

I have an Imac at work and an Ibook at home. Items entered on the Imac will always appear on both calendars and sync properly. Items posted at home on my Ibook, will NOT appear on my Imac at work. I also sync my address book and Safari Book marks and those always work fine . What do I need to do so that the items entered on my Ibook at home will appear on my Imac at work?
Thank you.

AlpineTom,
Welcome to Apple Discussions.
Be sure to try...MobileMe: How to reset sync data
As stated in that article: "If you reset the sync data, be sure you reset it from the computer that has the most up-to-date information on it. If at all possible, before performing these steps, you should back up your data."

My ical won't sync with iPhone 4 after IOS 6.0.1 update

My ical won't sync with iPhone 4 after IOS 6.0.1 update. The "sync calendars" option is no longer available after I installed this update. Any ideas???I have tried a few times to sync, and nothing has changed on my calendars. I have had so many troubles with this update. Grrr...

I tried the same but it did not worked. But, i got a solution. I accessed gmail on my laptop. Went to gmail settings. There is a option to add a device. A iPhone was already listed. I clicked Revoke to remove it. Then i clicked add new device and gave it iPhone name and a new 16-20 character password was geenrated. I used it to configure gmail on my Iphone and it worked beautifully. So glad i have been able to fix this. That password is a one time password to authenticate that device.

I Have a new iPhone 6 and my contacts, calendar and notes won't sync between my imac, macbook air, iCloud. The three are fine, but the data won't reach my new iPhone 6. OS Yosemite, iOS 8.1.1

I Have a new iPhone 6 and my contacts, calendar and notes won't sync between my ipad air, imac, macbook air, iCloud. The three are fine and they sync OK...but the data won't reach my new iPhone 6. OS Yosemite, iOS 8.1.1
Any ideas?
Thanks!

Hi vichochile,
If you are having an issue with syncing your new iPhone with the information that is in iCloiud (and on your other devices) we should make sure that iCloud is set up correctly on the iPhone. See this page for directions -

Thanks for using Apple Support Communities.

My problem is that my iCal won't sync from my first-generation iPad to my computer, and the computer sends events multiple times back to the iPad... which is now full of duplicate events. I'm NOT on iCloud.

I'm just an old lady who doesn't know a lot about this stuff, but I do love my iPad and miss my portable calendar! My problem is that my iCal won't sync from my (first-generation, cheaper of the two models) iPad to my computer, and the computer sends events multiple times back to the iPad... which is now full of duplicate events. I'm NOT on iCloud. I've had this problem for nearly a year now. My Really Really Smart son couldn't fix it for me.

Can take some time.... how much time?
There's no simple answer to that. My calendar goes back to 2004 and is moderately busy; it took around an hour. It's possible that you've hit a slow period on the server - it happens.
In order for it to work, your calendars should show on the MobileMe site, they should be listed under your MobileMe login name in the calendar list in iCal (calendars listed under 'On My Mac' will not sync) and your MM account details have to be entered in iCal Preferences>Accounts (this should have happened by itself).
If it's not working please see the page I linked to.

So iCal won't sync as I've had to change my gmail password. Anyone figured out how to fix this?

So iCal won't sync now as I've had to change my gmail password. Anyone figured out how to fix this?

Yes, I go to Settings>Mail>Gmail. I've deleted the old Gmail account and added it back with the new password. I've also deleted the account, shut down the iPad and iPhone and then re-add the Gmail account with the new password and it still doesn't work for either device. The error messages I get are:
For the iPad: Cannot Connect Using SSL
For the iPhone: The user name or password for "imap.gmail.com" is incorrect.

ICal won't sync from my MacBook Pro to MobileMe

iCal won't sync from my MacBook Pro to MobileMe. But MobileMe entries appear on iCal on the MacBook. My iPhone and iPad work fine. Any suggestions?

Hi melindybek ,
You are awesome and already a step ahead! The logs are blank, because by default they are off. If its necessary to turn them on the directions on, instructions of how to to this are at the end.
To check if they are both on the updated version, its possible to check by going to accounts.firefox.com to see if you are logged in. If so, both are updated. If not, how to update: sign in at that address to be on the new one.
Toggling the sync may jumpstart it too. Removing the account and adding it back starts a fresh sync, or Tools > Sync Now.
* How do I turn on sync logs:
# Open about:config and turn on: services.sync.log.appender.file.logOnSuccess and services.sync.log.logger.engine.bookmarks
# Restart Firefox and look at: about:sync-log
# Logs and error messages will be located here
Please also use pastebin.mozilla.org for sharring any errors that relate to this issue.
Thank you.

Ical won't sync with iPhone 5, iPad 2 or macbook pro.

I have updated my devices and now my ical won't sync with iPad 2, macbook pro or iPhone 5. How can I refresh them so they will all sync together. I just noticed that when I added an event on my ipad2 it did not show up on my macbook pro. I turned iCloud off then on again. I also turned calendars on and off again. Then the event disappeared from my iPad also. So now it is only on my iPhone 5. How do I sync ical with all my devices?

Anna,
I have tried everything suggested by the apple support webpage.
It would be helpful to know if you used this support article: iCloud: Troubleshooting iCloud Calendar.

ICal won't sync with iPad, iCal won't sync with iPad

My iCal won't sync with my iPad. Anyone know why? The iPad takes on the iCal but the iCal won't take the iPad entries.

Hello Squeegeefrog,
Thank you for participating in the Apple Support Communities.
You mention that iCal (or Calendar on OS X Yosemite) won't sync with your iPad.
Are you using iCloud Calendar? If so, the advice and troubleshooting steps in these articles can help you sync the calendar on your Mac with your iPad using iCloud:

Since downloading Maverick iCal no longer syncs between my MacBook Pro, my iMac or iPad - how do I rectify this?

since downloading Maverick iCal no longer syncs between my MacBook Pro, my iMac or iPad - how do I rectify this? (my first post ever)

I know Pete, but what if I don't have good internet connection sometimes?
Imagine:
this morning planning the whole next week with my iMac, bussiness around Europe.
I must go this evening.
Just now internet line fails in the neighborhood.
Stupid situation, and not so uncommon, cause not all of us are living in Manhattan. (this is what Apple thinks)
Cable must be an option beside iCloud.
true or not?

ICal bug subscribing/publishing between Leopard and Tiger?

It seems there is a strange incompatibility between iCal 2.0.5 (Tiger) and iCal 3.0 (Leopard).
I work for a company where 10 employees share their calendars through a private server.
Everyone publishes his/her calendar and is subscribed to all the other calendars within the company. So effectively, everyone sees his own calendar in iCal as read/write and all the other calendars as read- only.
Last week 3 machines were upgraded to Leopard and since then trouble started.
Now, when someone on a Leopard machine creates an event and invites someone who is on a Tiger machine, the Tiger machine can accept the invitation but as soon as it is accepted the event disappears from the Tiger calendar.
As soon as the subscription to the Leopard calendar is removed, the event reappears on the Tiger calendar.
The results are the same when a Tiger user invites a Leopard user on the Tiger machine.
I tried this both with a private server and dotMac.
Does anyone have the same experience and perhaps a solution to it?
Right now the only solution I see is to upgrade all the machines to Leopard.

Although I don't have a solution, I share your pain. I had less problems with iCal even before upgrading to Leopard.
What I can find across forums discussing bugs in iCal for Leopard is that, for the moment, there are a lot of small annoyances regarding alarms, compatibilities and inability to edit items without causing it to crash, amongst other topics.
The frustration level is growing as no sign of help seems to be come from Cupertino until now, the best help is on the forums, by power users themselves.
