ICal won't quit/monitor has commenced flickering

We bought our iMac 20" last January 2008 and it has worked perfectly. I have installed all updates. After the last update (and I really don't know if it is just coincidence...) iCal won't quit unless it is forced. All data is gone. It might also have something to do with the last time I synced my iPod...?
More troubling, the screen has started flickering... almost shutting down at points. However, it is not on a regular basis and seemingly out of the blue...?
Any help or advice would be greatly appreciated.

HI,
Try deleting this file. com.apple.ical.plist
/Users/YourName/Library/Preferences. Drag that file from the Preferences folder to the Trash, empty the Trash and restart your Mac.
See if iCal behaves.
*"More troubling, the screen has started flickering... almost shutting down at points. However, it is not on a regular basis and seemingly out of the blue...?"*
Run the Apple Hardware Test and see if it reports anything.
Not sure about the iPod. One problem at a time.
Check the startup disk just in case.
Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart

Wilrez,
Welcome to Apple Discussions.
Regarding the iCal issue, if you used Software Update for installing OS X 10.5.7, you may want to try reinstalling the update using the Mac OS X 10.5.7 Combo Update.
Let us know what happens with both problems after the reinstallation.

Address Book (and iCal) won't quit

Hi - I have a MacBook Pro Intel Core 2 Duo running OSX 10.4.11 (i know, i know i will get to leopard soon..) and recently Address Book and regularly iCal won't quit without being forced. There doesn't seem to be any problem operating either programs (though with iCal i have to re-adjust the frame size to see the entries) and Address Book updates up via iSync etc.. but it just won't quit.
Anyone got any thoughts?
Thanks,
Lloyd

HI Michael,
Using your restore disk(s) you could use Software Restore from your Applications/Software Restore and reinstall iCal and Address Book. Launch Software Restore and just follow the onscreen instructions.

Ical won't quit?!

I got a Macbook Pro for christmas and i entered a few events into ical and not it has a loading bar saying upgrading ical caladners and it won't go so i can't shut down the macbook properly as it says it failed due to this app. How can i fix this?

Put cursor to apple logo top of screen, Force Quit, and force quit ical

All events disappeared and iCal won't quit

Ok, I'm stumped.
I'm not sure if this started when I did the 10.5.5 upgrade or when I had a power-hit crash in the same time frame, but iCal seems pretty much dead. When I launch it, I see none of my events or groups - just a blank calendar. When I try to quit, the "iCal" menu shows blue but nothing happens. I can force quit but get the same results upon restarting iCal.
So, I have good backups and restored my user Library/Calendar and Library/Application Support/iCal folders. No change. Tried tossing the prefs and the Cache files per some other threads I've seen here - no change. Finally got out Pacifist and reinstalled iCal from my Leopard disk (which caused a number of other problems but sorted them out by reinstalling 10.5.5 update). iCal however, is still doing the same thing.
Anyone have suggestions for what I might try next?

Do the combo update for 10.5.5. For some reason, a number of us had the same problem when 10.5.5 update was first available. Even though I had 10.5.4 on my computer, ical worked (not) just like yours. Redoing the update as the combo one seemed to solve the problem.
Look for the thread ical hosed with 10.5.5.

ICal won't quit out

All of a sudden when I'm in iCal the "quit iCal" option is grayed out and I let it sit for a while thinking it might be synching but no matter how long I waited it wouldn't quit out. I force quit twice now but Finder doesn't indicate it's not responding. I'm all updated software wise on my MacBook Pro. Don't get it. Help?

I am having this problem also and would appreciate insight. I can only quit from the Dock.

30" has been flickering for months on start-up until warmed up. Also, brightness won't stay on, but cycles down repeatedly.

OK, I tried setting Energy Savings to 1 minute. The Mac shut down and would not power back up via the power button, had to pull power plug. So it seems to be tied to the Energy settings.

IPhoto 09 Faces wheel spins forever and/or won't quit

Hope someone has insight or it helps others...
For the last several days any import into iPhoto will set it into spinning the Faces album waiting wheel forever. There is no way to Quit. Other times just simple quitting won't work.
Activity shows 40-50% iPhoto CPU usage, lots of context switches (270,000 in 5 minutes of CPU time) but no hangs, no faults. I have previously let it run overnight, in case it was somehow reanalyzing 18000 images, but even then the problem remains.
Console shows: 10/12/09 3:55:58 PM iPhoto[653] * -[NSPathStore2 getCharacters:range:]: index (8) beyond bounds (3)
as most recent item from iPhoto in the log.
Looking inside the iPhoto Library folder the face.db database, iPhotoMain.db etc. have no activity going on. ( I tested by changing the face info on one picture, the Finder last modified date immediately changed, showing the processes are running fine, but just some runaway process won't quit.)
Another console item showed iPhoto finding wrong architectured PGP plugin in contextual menu items, so I have trashed that. And, it finds a Chronos Notes related issue (contextual menu item in library and same named alias in user/library) throw an exception. I also informed ChronosNet.com of this....in case the recent iPhoto acting up is related to the SOHO update that was recently installed.
"I've had iPhoto start acting up (fails to quit) since SOHO NOTES latest update... checking the Console shows a possible problem....
You have a contextual menu entry (alias) in user/library and same name (original item) in library. That makes apps like iPhoto throw exceptions...
10/12/09 4:29:33 PM [0x0-0x40040].com.apple.iPhoto[653] objc[653]: Class SBContextualMenuHelper is implemented in both /Users/imran/Library/Contextual Menu Items/ChronosNotesCM.plugin/Contents/MacOS/ChronosNotesCM and /Library/Contextual Menu Items/ChronosNotesCM.plugin/Contents/MacOS/ChronosNotesCM. One of the two will be used. Which one is undefined."
Let's see what they state.
Now.... Force quitting now to see what it shows in the logs:
It did not show any quick console messages. I'm surprised an OS X "report this crash to Apple" window did not open up.
Now relaunched... will see if it happens again...
Imran

iPhone is not "hung" in the traditional sense in that you can do several things within it while it's non-stop Faces spinning wheel displays. I do NOT find it responsive and it does NOT Quit when Faces is spinning forever. tgardner, your experience appears to be different.
Checking in Activity Monitor shows that interestingly there are no hangs or errors. But, looking into contents of iPhoto library shows NO files are modified even after 24 hours or running. In other words, maybe it's not dead, but it is comatose.
Also, checking in Console I always see a variable out of bounds error when this happens.
I have 19000 images and of those maybe 5000 have faces, of about 50 people. ALL of those images are already processed with Names info. Even if Faces needs to update some data, 24 hours of nothing but iPhoto running ought to be enough but it is not.
Others may want to check Console and Activity Monitor and add their experiences here.

Help Please! iCal won't close without "synchronizing modificatons"

I have iCal on an intel iMac running Tiger. I emailed my calendars from my old mac to my new mac and imported them into my new iCal. iCal won't close now, it says "Synchronizing Your Modifications" Abort and Quit is given as a choice, but it doesn't quit. What is this? HELP !!!

John,
To reinstall iCal:
1. Insert the Snow Leopard Installation disk into the computer.
2. The disk will appear on the desktop.
3. Double click on the "Optional Installs" folder.
4. Double click on the "Optional Installs.mpkg."
5. Click on (Continue) in Introduction.
6. Click on (Continue) in Software License Agreement.
7. Click on (Agree) to agree to the terms of the software license agreement.
8. Click on the disclosure arrow ▶ next to Applications.
9. Select (✓) iCal.
10. Click (Continue).
11. After iCal has been reinstalled, download and install the Mac OS X v10.6.7 Update Combo to bring iCal up to the most recent version.

Macbook won't shut down because finder won't quit

Macbook 10.5 Leopard, purchased October 2007.
Tried to shut down
Popup says "logout has timed out because application finder has failed to quit, to try again quit finder and choose logoput from the apple menu"
I tried ..... and nothing. Can't shut down.
I tried command option escape and that doesn't work.
Tried to force quit, and that doesn't work.
Somewhow   finder is still running no matter what and hence I can't shut down. This is very frustrating
Is there any way I can get the computer to have everything go dark and shut down? All the obvious instructions don't work
I have had to force quit in the past maybe 2 or 3 times in the past.    No biggie. But this problem of not being able to shut down even after force quit is new.
Nothing is connected to the   macbook except the external monitor, which has always been there.

If any of the apps won't quit on you in future, try ti kill them in Terminal:
killall Finder
then hit enter
If you don't know the official app name (how OS SX sees it), go to COMMAND_OPTION_ESCAPE and see the official name in the running app list.
The power button method above works 100%, but will bypass saving of session states for all services, so your OS X could be unstable after reboot and won't remember some settings you had prior to shuting down. Use it only as a last resort.

ICal on my MacBook Pro has been "updating" for days...??

I have an iMac, MacBook Pro, iPad and iPhone. I have been using iCloud since it came out (running Lion). iCal on my MacBook Pro has been "updating" for several days. Also - when I add an event on the MacBook, it does not show up on any of my other devices (they are all set up with the same iCloud calendars). When I add events from my other devices, they DO show up in iCal on my Macbook Pro.
I am at a loss -- any help would be VERY much appreciated!
Thanks
Kim

Hello
Chance upon your post and yes, immediately after upgarding to Mountain Lion, my "new" Calendar (Desktop, formely known as 'iCal') keeps having the pop up window saying "Updating Calendar..." (I set my Calendar to auto-launch after Startup)
After restarting it will still be the same, but if I quit and launch again, everything will be fine. Will try the method you posted (the thread) tonight. Although I deleted the iCal preferences, thinking/hoping it will help
However, I don't seem to have a problem with sycning of al events, my sync with iCloud and all my macs and iOS devices seem OK.
If events are not syncing into some of your iOS devices, why don't you try deleting the entire iCloud account on it and re-set a new one? I've done that before when events or other data don't properly sync
Cheers

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.

Mail.app using 80% CPU and won't quit - any ideas?

Hi, I'll try and cut a short story shorter...
I tried to begin using Mail.app last night instead of Entourage and Thunderbird just to see what it was like. Having never used mail.app before, I use the bundled import wizard to retrieve the settings from the Entourage account (POP, wifes ISP account) which seemed to work ok. I didn't test at this point as I have another account (POP again, my gMail) stored on Thunderbird which I also wanted to import.
To import the mailboxs from Thunderbird I copied the relevant folders from the ~\Library...\myprofile\... folder to the desktop and added the .mbox extension. Then used the import wizard 'other' option to bring them in.
All seemed to go ok. I recreated my 'other' account manually and sent/received some test mails etc. then marked everyting in all mailboxes as read.
At this point the laptop went very slow so I checked Activity Viewer - this showed Mail.app hovering between 70% - 80%. I thought this was a bit odd so I tried to Quit Mail, but it just hung. I then force quit and the CPU calms down.
I opened Mail again and it was ok for about 3 minutes until I try to view various mailboxes. Mail is still responsive but the mailboxes are empty! I use the rebuild function and they show the messages again, unless I look at a different one and then go back to the rebuilt mailbox - it's empty again.
Then the CPU/won't quit happened again. CPU is up at the same levels, Mail.app has 7 threads. I thought there may be some indexing going on so I went to bed. I got up this morning to find the G4 fans going crazy and CPU still consuming the CPU?
Any ideas?
I'm thinking I may trash both accounts and rebuild from scratch tonight.

Hi Ian.
Aside from whatever the problem is here (which I don't really know), you shouldn't add an .mbox extension to mbox files in order to import them into Mail. Mail uses that extension for something else. Also, you'd get better results using Eudora Mailbox Cleaner to do the conversion.

Print Proxy Queue Won't Quit

On my Brother MFC connected by USB, the printer proxy app won't quit after the print job ends, and you have to click the proxy app's icon in the Dock, then quit the app manually. (You have to close it, as the computer won't sleep by itself after x amount of time if the proxy app is left open.)
This is only intermittent. You can tell in advance if this is going to happen by not seeing a little piece of paper icon superimposed over the printer proxy app's icon in the Dock. No piece of paper icon = proxy app won't quit.
Tried reinstalling all drivers, archive/reinstall, using Printer Setup Repair to "reset the printing system," permissions, Cocktail to deep clean caches including printer caches, all to no avail. New printing cables, connected directly without a hub. Happened on my HP LaserJet 3330 which died, and now on my Brother MFC-2070. Happened when I was using a Titanium laptop also, before the current G4 tower. Happens across many apps, although Office seems to provoke it more frequently.
Ideas anyone, short of trying a totally clean install and reinstalling all apps an drivers from scratch to see if that helps? The OS install I'm working on is back from 10.2.0, and has been upgraded and archive/reinstalled multiple times, and has been used on multiple computers over the years. My Word 2004 Normal template dates back to Word 5.1 and has been converted/upgraded several times (6.0, 98, 2001, X, 2004; could this be a culprit as well); should I rebuild it from scratch (hours and hours of work there, many custom menus, etc).
