ICal won't launch

All of a sudden, when I click on iCal logo, nothing happens. I'm wondering if a friend who was sitting at my computer briefly could have trashed a pertinent file by mistake? The headers come up--file, edit, calendar, but I can't get the actual calendar to appear. Never had a problem before. Any ideas of what could have happened?

Hi,
It is possible that your iCal preference file may be corrupted.
In your user's Library > Preferences find a file called com.apple.iCal.alarmsCache.plist move this to the Desktop and restart iCal.

ICal won't launch in Leopard

After installing Leopard earlier tonight iCal won't launch. Whenever I try to open it I immediately get an "unexpectedly quit" error message. I've repaired the permissions in disk utility but that didn't seem to do anything. Any help would be much appreciated. I depend on iCal.

Look for files in a com.apple.ical...plist format. trash them and restart iCal.

ICal won't launch after 10.5.2 upgrade

my iCal won't launch after 10.5.2 upgrade. it won't even give an "unexpectedly quit" message, it pops up then quits, then nothing. This happened immediately after the upgrade today. I got the leopard disc out and did an archive and install then it worked perfect, no issues, then I did a software update (since I was back to 10.5.0), and installed the 10.5.2 security upgrade, now iCal will not launch, am I the only one with this problem?

I had the exact same problem -- doubled events and could not edit anything. I flushed the cache as describe in some more detail here: http://www.tipstrs.com/tip/2506/iCal-problem-with-Leopard-Upgrade and everything started working just fine.

ICal won't launch on mbp running OSX Lion 10.7.4

iCal on my MBP won't launch iCal or Mail. When selecting each I get a 'dock logo' bouncing once or twice but no response after that. Any thought's?

Good evening Ferd 11
Thanks for the advice. I tried the Safe Boot with no luck, however, the 'client combo' update has worked and Mail and iCal is now up and running.
I wasted 3 hours today at Apple's Genius Bar in Sheffield, UK, in our 5 minutes of conversation the 'muppet' suggested I went home backed up and did an 'erase and install' on the HD.
Pre iPhone/iPad the tech service in our Meadowhall store was first class. As a working pro photographer I was able to build up a relationship with the team, nothing was too much trouble! Good times, they had a guy called Al, weird hair cut but top bloke!
Many thanks for your hepl again, Shaun

Address Book and iCal won't launch

Neither my Address Book nor my iCal will Launch. I've tried binning the preferences and short of replacing the operating system I wondered if someone might have a view on this.

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 launch with Leopard

Just installed Leopard and now says I can't use this version of iCal with my new operating system. Is there another version to download?

magwill,
Welcome to Apple Discussions.
What version of iCal are you attempting to use? It should be Version 3.0.5.
Is the iCal you are attempting to use in your Macintosh HD/Applications folder?
How did you install Leopard?
Have you attempted to "Try Disk Utility" to Repair Disk Permissions?
There is no download of iCal available, but it can be accomplished using your Leopard installation disk. This is the procedure: (but I recommend that you answer my questions before proceeding)
1. Insert your Leopard Installation disk into the computer.
2. The disk will appear on your 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 reinstall the OS X 10.5.5 Combo Update to bring iCal up to the most recent version.

If iCal doesn't launch/display properly

Some general things to check for and do when iCal won't launch or doesn't display calendars/events/todos properly in Tiger. Try these things in order and make sure you understand each step fully before you start it :
0.
Backup your iCal data.
If you can, open iCal and go to the File menu and choose Back up Database... to save a copy of your calendar data to your Desktop, just in case something goes wrong.
(You should be doing this regularly anyway
1.
Is the problem with the Application or your user's data?
Make a new user account on your computer, and log in as that user. Open iCal as the new user. If you are still having the same problems it is likely that the problem is with the application and you should re-install it, if not the problem is with the data and you should move on to step 2.
To re-install iCal you will need your Tiger installer disk. On the installer disk go to System> Installation> Packages> (you'll need to scroll down to see the System folder). In here there is iCal.pkg, double click this to install iCal.
If this fixes your problem there is no need to do the following.
2.
Refresh your preference files.
There are some preference files related to iCal in your user's Library > Preferences. These are called:
com.apple.iCal.alarmsCache.plist
com.apple.iCal.AlarmScheduler.plist
com.apple.iCal.helper.plist
com.apple.iCal.plist
Quit iCal and move these files to your desktop. When you start iCal they will be re-created in the Preferences folder with the default values as needed. This does not affect your calendar data, just preference choices.
You should go into iCal preferences and make any changes you want to your preferences after doing this.
If this solves your problem delete the copies on your Desktop, there is no need to do the following.
3.
a: If iCal launches and you can see the calendar list:
Check the calendars in turn.
In iCal uncheck all the calendars in the list. You can do this by Command-Clicking one calendar's check box.
Then do the following with each calendar in turn: Check the calendar's check box and see if your problems still exist. If iCal seems to be ok, then uncheck the check box and select the next calendar. If the symptoms still exist then this calendar is probably corrupted.
If you find a corrupted calendar in iCal, select it in the calendar list and from the File menu choose Export.. and export a copy of the calendar to your Desktop. Still in iCal, from the Edit menu choose Delete to remove the calendar from iCal. Then from the File menu choose Import... and select the 'Import an iCal file', find the calendar file you saved to your Desktop and import it.
Go to step 4.
b: If iCal does not launch or you can't see the calendar list, it's a bit more involved:
Using the Finder to remove the data and replace it in turn.
Make sure iCal is not running, then go to your user's Library > Application Support > iCal> Sources folder, and copy this entire folder to your Desktop.
Go back to your user Library > Application Support> iCal> Sources. In this folder there will be one folder for each of your iCal calendars. These have long alpha-numeric names. Open these folders in turn and delete the file corestorage.ics in each one.
Open iCal. It should launch now, but there will be no events/todos and each calendar will have an exclamation mark by it.
Close iCal and repeat the following for each folder in iCal's Sources folder: (I found this easiest to do if you open both Sources folders next to each other in Finder's List View) From the copy you made to the Desktop, move the corestorage.ics file back into the correct folder in your Library> Application Support> iCal> Sources, and open iCal. If iCal is launching and functioning ok then the data in this calendar is good and you can move on to the next calendar.
If the symptoms you originally had have returned, then this calendar is corrupted.
With the corrupted calendar, move the relevant corestorage.ics file back to the correct sub-folder on your Desktop> Sources folder. In this folder will be a file called Info.plist. Open this file in a text editor, and look for the line that contains <key>Title</key>. The following line contains the title of the affected calendar between string tags (e.g. <string>Home</string>). Open iCal and with the calendar of this name, click the red exclamation mark and choose 'Reset' from the resulting dialog. Quit and re-open iCal. In iCal, make sure the same calendar is selected in the calendar list and drag the corestorage.ics file onto iCal's main window. (I got warning dialogs about unsafe alarms - I went with keeping the alarms.) This should clean up your calendar's data.
4.
Reset sync history.
If you have sync-ed your calendar data (either with .Mac iSync or third party apps.) there may be a corruption in the data stored by Sync Services which will be passed back into iCal when it syncs next.
Open iSync and from it's preferences select 'Reset Sync History' and in the confirmation dialog choose 'Reset Sync History' again.
I hope this will be of help to anyone having these types of problems. This (obviously) is not intended to be complete solution for every problem you'll come accross in iCal.
Please, feel free to post and correct my errors.
Thanks
John M

Hi Nancy,
> When I go into LIbrary>Application Support> there is now no ical.
Hmm, looks like you are having some problems there. (You are looking in the Library in your Home folder aren't you?) Were able to make a backup .icbu file as I suggested in point 0 above? If so you might want to open iCal and select File> Revert to Database Backup... and revert to the data you had before doing this, and start over again.
Otherwise, do a Spotlight search for 'iCal' and look at all the folders returned titled iCal. The most likely explanation is that you have inadvertently moved the iCal folder from your user's Library> Application Support to somewhere else on your harddrive. If this is so move it back.
Where exactly were you in the process? You say step 4, that is about re-setting iSync.
You say you moved the 'corestorage.ics' file to the Trash (and then emptied the Trash). Are there still corestorage.ics files in every folder in Sources on your Desktop?
> I still have the sources file on my desktop.
Keep it there. You might want to re-name it 'Sources Old'.
> when I click on the desktop sources folder and try and go into plist it is coming up as an itunes doc and attemptint to open with itunes
You seem to have plists associated with iTunes for some reason. To see the file's contents Control-Click one of the plist files and choose 'Open with' from the contexual menu and open it with TextEdit.
Please let me know how you get on.
Best wishes

Logic won't launch in Leopard

Hi
I am new to this forum so forgive me if you have covered this, I have searched the forum for an answer but no luck so far. I have just installed Leopard and updates and now both Logic Pro 8 and Garage band won't launch. I can only launch Logic if i don't use the core audio so it's just for midi, but as soon as I try to use the computers audio side it crashes. can anyone help me solve this issue ?
many thanks

Ical will not launch (OS Mavericks)

Hello
I am using OS Mavericks (10.9.1) on my 2009 MBP. I tried opening iCal today (as I normally would, by clicking the icon in the dock). The icon bounces once and nothing happens. I tried finding a solution online. One user suggested removing the Preferences plist for ical, which I did. Still, iCal did not launch. Then, another user suggested removing ical and reinstalling. As I have the disks for Snow Leopard, I reinstalled iCal.
When I try to launch iCal from the Application folder, I now receive the following message: "You can't use this version of the application "iCal" with this version of OS X. You have "iCal" 4.0."
Now what? Any suggestions? Many thanks!

To clarify, if you're running Mavericks, there is no iCal. It was replaced by Calendar.
The Calendar app in Mavericks is not the same app as the iCal app in Snow Leopard. And, as you've already found out, the iCal app from Snow Leopard won't run in Mavericks.
If you deleted the Calendar app form Mavericks, the easiest way to get it back would be to re-install Mavericks. The correct app for Mavericks is Calendar (version 7.0).
You have also posted your question in the 10.7 Lion area instead of the Mavericks area.
I've requested the Moderator to move your post to the Mavericks area.

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

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.

Have a problem with Lightroom 5.4. Since the program crashed yesterday it won't launch, it comes up with the message "Lightroom encountered an error when reading its preview cache and needs to quit". " Lightroom will attempt to fix this problem next time it launches". Except that it doesn't, I keep getting the same message and the program closes. Does anyone know what I can do to repair it? Can't back up, can't do anything.

There are dozens of threads in this forum that describe the fix

Photoshop CS6 won't launch and when it does it's really slow...help?

Hi,
So my copy of Photoshop CS6 sometimes won't launch and when it does manage to launch fully, it's really slow. I mean ridiculously slow. The only times when I can get it to run even remotely quick is if I shut down my computer, and then restart it and then start up Photoshop CS6 as the first program. Even then it slows down after a while. (And I only have a firefox browser open usually, never more than a couple of tabs at once, so it's not a bandwidth issue)
Here are my comp specs:
Samsung
Processor:
AMD A6-3420M APU with
Radeon (Tm) HD graphics 1.50 ghz
Installed Memory (RAM) - 4.00 (3.48 usable)
64 Bit operating System running on Windows 7 home premium, service pack 1
I also did just recently install the new update Adobe had for Photoshop, so that's up to date.
It's getting really frustrating! I have another program I'm using in the meantime (Paint tool Sai), but I'd really like to use Photoshop CS6.....
Any help would be greatly appreciated!

Make sure you updated the drivers from AMD's website, not Microsoft.
Make sure you are running the 64 bit version of Photoshop, not 32 bit.
Disable all third party plugins, and try disabling system utilities (we've seen font managers, antivirus, disk backup software, etc. cause slowdowns due to bugs in those utilities).

Mail won't launch nor its settings save/ allow changes after 2.0

Anyone else have this ? Mail just won't launch ; opens to the main scroll screen, which stays blank, with the top and bottom bars showing – the bottom bar showing the refresh and write buttons – and then quits. Also, I cannot delete my MobileMe or GMail account, nor edit them.
Though with the MM account, if I try to delete it, it disables all of the push functions except mail. Things that I've been trying to do, like change whether the Trash folder autodeletes mail or not and the name of the account, don't save at all. The Trash delete frequency change stays in place as long as I'm in the Mail settings ; the name change doesn't hold at all.
In the second setting 'pane' in Settings – "Nouvelles Données" in French, so I guess "New Data" ? – down in Advanced, there are two MobileMe Push accounts listed. The first one saying it syncs calendars and contacts, and the second one mail... Yet I only have one MM account set up, or so says the uneditable Mail settings.
Nor can I (re)add my MM and GMail accounts. Trying to add a Yahoo account I never put on the also failed.
I've restarted my touch too.
Sounds like one of those things that when on a Mac, deleting a plist or fixing permissions would be suggested... I can't find a similar Settings-related problem anywhere on the internet either.
Reïnstall?

CS3 Installer Won't Launch

OSX 10.5.5
Intel Quad Core Tower, 8GB Ram
Currently installed: CS3.3 Master Collection
I am trying to reinstall Acrobat 8 from my Master Collection 3 disc, and Setup won't launch. I've also tried Utilities:Add or Remove Adobe Creative Suite 3 Master Collection, and it won't launch either.
I've tried the standard solutions: fix file permissions, install from admin account and new user account, uninstalled CS4 Beta applications. Nothing has helped.
Adobe technical support has been no help. I've been on the phone with them for two hours this morning.
Any suggestions would be greatly appreciated! Thank you!

BRIAN, HERE'S WHAT WORKED FOR ME, BUT I WAS USING WINDOWS XP PROFESSIONAL, NOT A MAC SYSTEM. STILL MAYBE IT MAY BE OF HELP.
I had problems uninstalling and reinstalling my Adobe Master Collection CS3. The problem being that the installer would run and then disappear without initiating the uninstall/installation process.
Here are the simple combination of steps which worked for me.
1/ removing Adobe Master Collection CS3 by running add/remove programs
2/ running the Adobe CS3 clean script. I'm almost 100% certain I chose option 1 when running the script http://www.adobe.com/support/contact/cs3clean.html
3/ out of desperation and realising I had nothing to loose because I had an image of the fairly newly configured hard drive I was using, I deleted the Adobe "Installers" Folder located inside the Adobe folder at C:\Program Files\Common Files\Adobe
Steps 1 and 2 above did not solve my problem.
Step 3 did solve my problem. However, I do not know if step 1 and/or 2 were required for step 3 to work.
GOOD LUCK :-)
PS. Please let users of this site know if this solution has worked for you ...and if so, pass the solution on elsewhere too.
