Mountain Lion Calendar New Syncing Problems

I have had all my macs and my IOS devices synced through iCloud since it was MobileMe.   Everything has been wonderful (mostly) in terms of syncing, but in recent days, I have an issue where one of my calendars will no longer show events on the Macs.
At the beginning of the school year, I created a new iCloud calendar for my daughter's school.   I then uploaded a calendar export into that calendar so I could sync her school events across all of our devices.   Everything was wonderful.   Just a few weeks ago, I noticed that the events on that one calendar NO LONGER show on ANY of the Mac's - I think this is since the 10.8.2 update.    It only happens on this particular calendar.
Note that all of the events still show on icloud.com.   All of the events still show on my IOS devices.   They just stopped showing on my Mac's.   The other calendars show just fine.   I've gone through removing iCloud sync and re-enabling, but I get the same results.   I can add new events on any of the devices and they show up across platforms and online.   It's just those original 200+ events on the calendar that I put in for her school that no longer show.   Again - they showed fine for 2-3 months...
Please help!

Back up all data.
Delete the problem calendar accounts in the Mail, Contacts & Calendars preference pane, then add them back. Make sure the account details are correct. Test. If it still doesn't work, please describe in more detail what happens.

Mountain Lion calendar and notes sync problems with exchange server via WLAN

After upgrading to Mountain Lion calendar and notes do not sync anymore with my exchange server via WLAN. There are no syncing problems via ethernet if WLAN is deactivated. Mail works fine with both connection types. Similar problems known? Solutions?
Thanks for any ideas.

Exact same issue ... cropped up in the past 2 weeks. Constantly syncing and re syncing. Watching calendar events show up and disappear. Tried all the normal stuff including deleting and re setting up the entire acct ... no luck. It built out the whole calendar correctly ( from what I could tell) and then started to sync again and appointments randomly appeared and disappeared .....

Since installing mountain lion i have a problem with mail. when i delete a message close and open mail the message has come back. please help!

Since installing Mountain Lion i have a problem with Mail. I delete a number of messages from the same person but keep the newest message in my Inbox. I actually delete them from the Trash. The next time i open Mail the deleted messages are back again. Can anybody please help as this is getting annoying. Thanks in Anticipation.

Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.
First, empty the Trash.
Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):
find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl $ 2> /dev/null | wc -l
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.

Mountain Lion Calendar 'Search'

The 'Search' function in my Mountain Lion Calendar does not work. Any suggestions please?

Hmmm... Is there really no one else out there that has this problem? Because I'd think searching a calendar program by date range would be a fairly important thing to be able to do. Perhaps I'm doing it wrong? Maybe there's an FAQ somewhere?
Thanks,
Tom S.

I participated in getting the free download of Mountain Lion for new Mac owners. It took me three days to finally get a code to do it and when I tried downloading it, the estimated time was 74 days 17 hours. Now an error occurred. What do I do?

I am very frustrated and just want the great software to download in a resonalbe time!

Take your Mac to a location with a fast, relaible Internet connection that will be all yours during the duration of the download.
If you want to complain, PLEASE call Apple and do so.
Internet only downloads of OS X is completely stupid, it assumes everyone has reliable Internet everywhere and /or no data caps.

In mountain lion calendar, the alerts on give you a "close" or "snooze" options. What happen to being able to select how long you wanted to snooze your alert?

n mountain lion calendar, the alerts on give you a "close" or "snooze" options. What happen to being able to select how long you wanted to snooze your alert?

SnoozeMaster is now avaiable from the Mac App Store, for MacOS X 10.8 and up.
https://itunes.apple.com/us/app/snoozemaster/id614955483?mt=12
It addresses this exact issue. You'll be able to configure different pre-set snooze times, enter custom snooze times when an alarm triggers, etc. It's what snoozing should've been from the get go.

Outlook 2011 and mountain lion calendar sync issues... resolved (kinda)

Okay... I never really post to these boards, but I'm fairly ticked off that OS X keeps tampering with MS Office and it's syncing with iTunes and, ultimately, my iPhone. Apple support tried to push me onto the iCloud, but I'm not going to use that crappy feature. After many hours of trying to fix the calendar sync issue with MS Office 2011, I found a workaround:
1. Get the apple reminders set up to recognize the OS X Calendar program.
2. Confirm that your Outlook calendar data is recognized in the OS X Calendar program (it was always there for me)
3. Install MS Office 2008 (Entourage) --- You don't have to use it, but the older program still syncs with Mountain Lion.
4. Sync your iphone with itunes and ensure that your Calendars are erased (uncheck the Calendar sync box).
5. Click on the "Replace Information on this iPhone) for Calendars.
6. Re-sync the iPhone with iTunes.
7. The data should go up with no problem.
IF you are still having problems...
1. go to OS X "Calendar" and Add a new calendar called "Home".
2. move the Outlook data to the Home calendar (just drag and drop).
3. Repeat steps 4-7 above.
Since I've done these changes, everything directly syncs.
Hope this helps, and don't lose faith. MS will come up with some type of patch.

Outlook 2011 is not compatible with iCloud, it won't work and your 'workaround' may affect iCloud clients on the same account.
Don't use 2011.

Mountain Lion Calendar problem

hey everyone
I have just upgraded to Mountain Lion, but I am having a small problem. My iphone and ipad will share calendar dates via the cloud but for some reason I cannot seem to get my mac to communiate with either so the mac will not pick up the calendar on my phone and ipad. Any advice, I realize this is probably something simple, but I am just not seeing it.

I am still having problems. Things are either really slow in showing up or not really doing so at all. I added an event on my ipad and then nothing shows up on my phone or mac, but some things that got deleted on one are gone on the others
Are old dates on the phone/ipad non-syncable and only newer dates show up? I tried this too and its not showing up

OS X Mountain Lion calendar app not syncing with iPhone 4 calendar.

After installation I noticed that my OS X calendar was not syncing with my iPhone 4 calendar running version 5.1.1. Any sugestions to fix this issue.

Please note that all my settings are exactly the same as they were in Lion. I do not use iCloud and I like to sync thru iTunes via WIFI and USB. After further research I have discovered that this issue is seems to be with Mountain Lion. Obviously, Apple needs to update iOS 5.1.1 or release a fix for Mountain Lion.

10.8.2 Mountain Lion Update Causes Major Problems

I'm running an early 2009 iMac and I made the jump to Mountain Lion about a month ago. Initial upate ran OK, I had some problems but overall it ran pretty decently. I held off on updating to 10.8.2 because I wanted to see if it caused any issues, but decided to go ahead about a week and a half ago. Since then, my computer has had daily problems. To name a few, my computer completely crashes when going into sleep mode and will not return, the sound frequently disappears and goes unrecognized. iTunes has been an utter disaster - I have an iPod classic, which as soon as I plug in causes iTunes to crash. I've had similar issues with my iPhone 4. Airplay drops regularly when I never had that issue prior. Homesharing in particular causes iTunes to crash, which was working infrequently as of just yesterday.
I've had quite a few issues, which over the past few weeks has rendered my iPod classic and old iPhone completely useless as I cannot sync them to put music on them (I restored iPod to see if that would fix it, but it didn't. So now I have an empty iPod that won't sync). And the workaround of using homeshare was viable as an alternative, but now does not work at all. Connecting to my Apple TV takes 5-10 times longer than it previously did, and the connection occasionally drops. I used all these features with a regularity which makes this extremely frustrating.
Not sure if Apple plans to fix this with iTunes 11 update, but I'm hoping something will come about soon. I called support to inquire about downgrading back to Snow Leopard, but the guy on the phone convinced me to reinstall the OS, which I did. It has not solved any of my issues (although I was finally able to update my iPhone 4 to the latest firmware, it will still not sync or do Homeshare). Any ideas how I could solve these problems? These all started happening the day I updated to 10.8.2 and, as I said, I hadn't experienced anything like them previously.

I have done that, several times.
So this is where I'm at now - last night, immediately after finishing a movie that was on my WD hard drive, which holds all of my media, music, movies - I restarted my computer and then it would not read the drive. It said it was unreadable.
I brought the Mac and the drive into an apple store today - they said basically it was my hard drive causing the issues. I used my iPod classic as my media back up as the 160 gb could hold all my stuff. Well, as I mentioned previously, that can't sync and I restored it, with no success. So in essence I lost my media drive and the back up. Tough to swallow, I'm angry, I think it's still mountain lion causing the drive to fail.
So I resolved to go home and restore my computer to one of my time machine back ups and do a Snow Leopard reinstall. Well, the moment I returned from the apple store, the time machine drive is now listed as unreadable. I called support, spent hours with them - I now have two drives which fried within 10 hours of each other in the same error. The senior support manager agreed it sounds like mountain lion is indeed corrupting my drives somehow. My iMac currently won't start into the recovery disk. So I went out spent $200 to get a new hard drive, which I am now backing up my data onto with a new Time machine.
In the last week, I've lost my iPod classic, iPhone 4, two external hard drives and now possibly even the Mac itself. I'm going to install snow leopard and see if it alleviates any of my issues, or hopefully can read my drives. I truly believe Mountain Lion is the problem.

How to install Mountain Lion on New Macbook Pro from APPS

How can I install Mountain Lion into a VM on a New Macbook Pro running YOSEMITE from APPS
I have it in my apps purchased but It tells me the system is to New to download/run it
I have tried mounting my install ESD copy but it has the same Problem
I don't have another Mac
Thanks

I think the problem is that you can't install an older OS X version onto a system running a newer OS X version. So I would try the following:
     1. have an external disk or create another partition on an internal drive to use for the Mountain Lion install (you might have to shrink an existing partition to make room for another)
     2. Create an external bootable USB thumb drive with the Mountain Lion OS on it (do a search on the web for this - for example see http://www.macworld.com/article/1167857/how_to_make_a_bootable_mountain_lion_ins tall_drive.html
     3. Reboot Yosemite and then boot from the USB thumb drive by holding down the option key
     4. run the mountain lion installer and install on the new disk/partition you created in step 1 - it will also create another recovery partition from this same part of the disk
Now your Mac system will have both a Mountain Lion install as well as the Yosemite install. You won't be able to use Migration Assistant to move things from Yosemite to Mountain Lion because it will see that you're "going backwards" and won't allow you to.
Have a good backup of everything before starting in case there are problems.
Good luck...

Mountain Lion calendar .ics invitations don't go to date of event

Hi there,
I installed Mountain Lion recently as a stepping stone to Mavericks.
When I receive Calendar invitations in the form of .ics attachments and open them Calendar does not take me to the event.
This means that I have to trawl through Calendar trying to find the event before I can see if it clashed with anything else and accept it.
I was using Snow Leopard before and .ics files would always take me to the correct date on the Calendar.
Ant ideas on how to fix this would be greatly appreciated.
I've searched the forums for hours but not come up with anything. Possibly because I'm not entering the correct search terms? I don't know and I'm frustrated by this new foible.
Many thanks,
Richard.

Mountain Lion Calendar won't launch my Applescript

I've just upgraded to Mountain Lion and find that my previously automatically launched Applescripts, open but do not run.
In 10.6, to run scripts unattended, I just created an Ical event with an alert that ran the script.
This event was saved in the upgrade. My script still works, but now Calendar just *opens* the script. It doesn't run it.
So where are you supposed to schedule things like this in Mountain Lion?
For those who care - what the script does is copy text from a Safari page and save it to a text file.
I need it to run every half hour.
It doesn't run anymore, unless I am there to click the "run" button when calendar opens the script.

Problem solved with thread titled (re)Enable iCalendar ability to execute AppleScript

Mountain Lion Calendar is stripped of Publish options?

Here is my issue:
I have Outlook 2011 and it will only sync it's calendar with an On My Mac calendar.
10.7 (Lion) version of iCal only supported publishing to MobileMe or a private server. That's no good for me.
So I upgraded to 10.8 hoping the new Calendar would feature publishing to iCloud. Nope.
In fact the only publishing option for On My Mac calendars in 10.8 is a private server.
I created an account with a server (fruux.com) but it still doesn't work.
How can I sync my On My Mac calendar with Google or any other private server... or iCloud?
Help please!

Outlook 2011 is not compatible with Cloud services unless they are Microsoft cloud services (Exchange) This is Microsofts choice.
Check with Google whether they have a utility that works around MS's limitations.
I would use something other than Outlook if I wanted to use iCloud or other Cloud services, Mail, Contacts and Calendars are compatible, and they are on your Mac.
One user claims to have found a workaround to use Google, reprinted below.
I finally found a work around to synchronize Outlook 2011 with Google Calendar!
First I set up Sync Services to sync my Outlook 2011 calendar to iCal calendar. I make sure that I have all the categories that I want to have in my Outlook and create some event for each category so that it gets created in the iCal calendar as well.
Then I downloaded this software called "Spanning Sync 3", installed it and set it up with my Google account (Spanning Sync is a paid software with a 15 day trial if you want to try it first). After that, I can do the setup for syncing the iCal with the Google Calendar by mapping the categories in iCal to the categories in the Google account.
What happens is that when you create, modify or delete an event in Outlook, this event gets synced to iCal which in turn gets picked up by Spanning Sync and syncs to Google Calendar. Similarly, any changes in Google Calendar gets synced to iCal via Spanning Sync which in turn gets synced back to Outlook. This solution does not involve CalDAV to sync to Google Calendar.
Hope this will help someone else out there

Notes Application on Mountain Lion Won't Sync with Gmail

Within the past few weeks the new Notes application won't sync with my gmail account. I used to be able to type a note in Notes, and it would appear under the label "notes" as an email type memo in Gmail. All of the sudden this stopped working. Same with the Mail app, I can't sync IMAP with my Gmail accounts. This just started happening a few weeks ago.
Mountain Lion 10.8
