"iCal can't read this calendar file. No events have been added to your iCal calendar."

How do I deal with this error message-"iCal can’t read this calendar file. No events have been added to your iCal calendar." ? .ics vs .vcs?
Thanks

Greetings,
What version of the Mac OS and what version of iCal are you running?
Are you using MobileMe calendars (or any other server based calendars like Google) in your iCal?
While you answer those questions you can try the following troubleshooting:
1. First make an iCal backup: Click on each calendar on the left hand side of iCal 1 at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.
2. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
---NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
Once the computer is back up and running open iCal and test.
Hope that helps.

I haven't added events but am getting "This calendar is unreadable. No events have been added to your iCal calendar"

I recently started getting the message "This calendar is unreadable. No events have been added to your iCal calendar". However, I typically add my events by typing them myself either on my MacBook Pro or my iPhone. I don't import from outside sources. I don't know if it's related or just coincidental that around the same time, events that I add to my MacBook Pro are not syncing to my iPhone, but the events added by iPhone seem to appear on my MacBook Pro and my MiniMac. Is there a way to find the event that is being referenced in this error message??

iPhone:
Plug in your iPhone
Go to iTunes > Your iPhone > Info and ensure that calendars is not checked off to sync -- if you are using MobileMe to sync, this option should not be checked
On both Macs:
1.) Go to Apple > System Preferences > MobileMe > Sync and remove the check Mark for calendars. With the new MobileMe calendar system there is no need to have this checked. Close the MobileMe window once this is complete.
2.) Open iCal and then go to iCal > Preferences > Accounts and remove the MobileMe account from here with the minus sign.
3.) Go to iCal > Quit iCal
4.) Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
5.) Open iCal and go to iCal > Preferences > Accounts
-- If the MobileMe Account is already here remove it again and then re-add it being very careful to use the correct name and password (for your 10.5 system follow these steps for re-adding: http://support.apple.com/kb/HT4330)
-- If the MobileMe account is not already here, add it in.
iCal will download your calendars from the MobileMe server. Watch and see if you get the error message. If it completes the download (little spinning gear stops spinning next to the MobileMe calendar) go ahead and add a new uniquely named event to one of your MobileMe calendars on both computers and see if it syncs between.
Let us know what happens.

Why do I get "iCal can't read this calendar file. No events have been added to your iCal calendar." when I am trying to sync an Apple Workshop appointment?

I made a reservation for an Apple store workshop, but when I try to open the download in iCal (Lion) , I keep getting an "iCal cannot read this calendar file." message. Very frustrating. Any insights would be appreciated.
Thanks,
Bmoregirl

.ics file error : "iCal can't read this calendar file."

I would like to add my flight itinery to my iCal. Downloaded the .ics file from the BA website. When double clicking on it and dragging it to iCal this message pops up: "iCal can’t read this calendar file. No events have been added to your iCal calendar."
file details:

I also tried converting it to .vcs. Then iCal asks which calender I would like to add it to but still comes up with above message.
Any ideas?
Thanks.

Hi!
I managed to import the file when I deleted everything that had to do with HTML code at the end of the file. I'm not exactly sure about the purpose of this code, but deleting it left me with my flights inside my calendar, exactly as I wanted.

You need to associate your music files to iTunes instead of HP.

Double click on the relevant item and select iTunes from the list.

Fix for tiresome, "iCal can't read this calendar file. No events have..."

I've read a hundred posts about this problem, but the typical answers--erase blank space at the top of the file, rename the file "ics", etc. don't work.

Hi,
There are various reasons why iCal won't read that file.
1. Spaces at the end of lines (eg after the last "END:VEVENT"). I'm not sure if this is incorrect, but iCal does not like it.
2. The format of some of the dates/times is incorrect. (see http://www.apps.ietf.org/rfc/rfc2445.html#sec-4.3.12 and http://www.apps.ietf.org/rfc/rfc2445.html#sec-4.3.4 if you're interested).
3. The UIDs for the two events are not unique. Perhaps this is something you edited? (see http://www.apps.ietf.org/rfc/rfc2445.html#sec-4.8.4.7 )
This works in my iCal:

How can I read this xls file to vibration mkeasurement blocks??

Hi,
I want to use vibration toolkit to read and analyse
measurements given in this file. First column is time data and second is measurement value in mV.
Emir

SALKOx.xls ‏130 KB

Hai,
File I/O palette has a vi named "Read from spread sheet file.vi" that will read the file in specified path and gives the content of the file as
2-D array.
Read the measurement file with this vi and carry out the analysis.
With regards,
JK

I can not fint the texture files, which should have been installed with the CS6 and CC? why?

I installed Photoshop CS6 a while back. Later on I discovered that the texture files where missing, or not included? Later I installed Photoshop CC, to see if the texture files were included here. But no, it was not. As far as I concern, I know that the texture files are included, and should have been installed, but they were not. Someone have any idea why?

In Photoshop CC 2014, Filter Gallery opens the dialog below, and "Texture" is the last folder.

How can I read this avi file in Premiere?

My friend gave me an avi file (created in AVS Video Editor) for me to synch the sound on, but I cannot get it to play in Premiere CS4. In Windows Media Player it plays the video but not sound, and in Premiere it plays neither. Do I need to download a codec or something? Please advise.
audio codec 0x0055 MPEG-1 Layer 3
44100Hz 256 kb/s tot, Stereo
(codec installed)
video codec H264
name H.264/MPEG-4 AVC

Along with Harm's suggestion, this ARTICLE will give you more background on AVI (and MPEG, MOV, WMV, etc.) wrappers, and how to always be able to "peek" inside those wrappers to see what exactly is inside.
For adjusting sync, if you are having any issues, this ARTICLE might be useful too.
Good luck,

I created an Imovie on Ipad. Before exporting the Imovie, I deleted the video clips from camera roll. Error message "this proj. contains clips which have been deleted from your photo library." Help! Can I recover the "preview" file of my video in Imovie?

Is there an app out there to find the files within Imovie app on my Ipad where the Imovie "preview" is playing from?
I deleted the original vidoe clips from my Camera Roll before exporting the Imovie to Youtube because my camera roll was out of memory.
I'm using the latest Imovie app for Ipad.

When in iTunes can you "Add to Library" when new folders have been added but not in your library collection

or will they make duplicates of what is already there? If so, what is the best way to update the library?

I'm not sure I understand your question. If a file already exists and you add a second copy of it, it will add it again and you'll have a duplicate. It has no way of knowing that one copy of the file is identical to the other. If you add the same file twice it may notice it as the same as one that is already there and ask you about it first.

How can I change the names of catagories that have been added to my music library? Is it possible to change names or artists or gendre and how to do it?

How do I change the names of artists or gendre in the itunes list after importing an album? Is it posssible to change that information?

Yes. Select one or more tracks (use ctrl or shift clicks to add/remove or extend a selection) then right-click or press CTRL-I to Get Info. Use the different tabs of the dialog to make changes.
For general advice on getting things neat & tidy see my article on Grouping tracks into albums.

ICal unable to import this .vcs file

I have tried various edits to this vcs file that a site I use generates but have not been able to have iCal successfully import the file. I get the error message when using "import a vCal file": "This calendar file is unreadable. No events have been added to your iCal Calendar." Any idea what I need to change to get iCal to import this vcs file ?

Solved!
Go to Solution.

Yep, there was an error doing the calendar sync...There are a host of reasons:
incompatible fields
prior versions of syncing software still on computer
cache not cleared
calendar data in the wrong folder
too many calendars in iCal and on device....
the list goes on
4.6.1.305 hybrid
