Calendar not importing .ics

BTW, I've decided to use Outlook. I just works.

I got the same Problem OSX 10.9.5 Calendar 7.0. Solved the Problem through opening the .ics in TextEdit and changed "Method = Request" to "Method = PUBLISH".

+1 changing the METHOD:REQUEST line to METHOD:PUBLISH

Is this something someone can engineer a simple script for to re-tag files accordingly? Maybe as a Mail plugin or something? I'm no software engineer so this is a bit beyond me...

iCal seems to have problems to update when .ics are changed - for example time of the meeting.

Sometimes it worked for me to delete the invitation and import it again - but sometimes it did not work.

Now I found a ugly hack: Open the ics in an editor and modify the UID:xxx. Save, delete old entry of invitation and import hacked invitation.

This is not the way thing should work. Otherwise it is not an option to miss important meetings ...

I had the same problem.

After import in iCal the new item appeared and then within 1 sec disappeared.

When hacking I found that if this tag was changed or deleted then the ICS files get imported in iCal fine:

X-APPLE-ETAG

You can use this perl command on the CLI to quickly change a ICS file:

perl -pi -e 's/X-APPLE-ETAG/NOT--X-APPLE-ETAG/g' filename.ics

This command to do it quickly for a lot of files:

find . -type f -name '*.ics' -print -exec perl -pi -e 's/X-APPLE-ETAG/NOT--X-APPLE-ETAG/g' "{}" \;

I was able to re-import 3 calendars with >100 ICS files within seconds!

This problem has been a frustration for me for quite some time now. I have tried all of the suggestions above and still cannot get Calendar to save or even open iCal invites that come from Mail. I have no problem open and adding the exact same invite when using iOS on my iPhone or iPad. I also have no problem with the invite when using Outlook. I have just resorted to the inconvenience of just using my iPhone or iPad to add appointments. It works, but I'm baffled that the two, highly used, Apple Apps (Mail and Calendar) won't work together on an Apple Mac and that the problem has continued for - according to this thread - years.

THANK YOU for posting. this was driving me crazy.

I have just upgraded to OSx El Capitan and it appears to have resolved this problem. I can now double click on an invite in my Mail program and it is added into Calendar. Unfortunately, it seems that it won't sync those events my Exchange server. I can add an event into Calendar and it will sync. But if I double-click on an event from Mail, although it adds it to Calendar, it won't sync through the exchange server. Jeez... always something.

Calendar invites stopped automatically populating a few months ago for SOME things. I can't find a pattern. Started hitting "add to my calendar" on the web and downloading the .ics event. Tried most of the suggestions above on my MAC, opening with Calendar instead of calendar file handler, dragging, doubleclicking, etc. None worked so have been duplicating the event manually. Not a good work around.

Just went to do the "add to my calendar" on my iphone 6plus and it populated and then it auto synced with my Mac calendar. Better work around...not ideal.

I hope this gets fixed as it looks like it has been an issue for some time according to this thread.

Thank you! This method worked for me.

It is how to comprehend 4 years after this post was started the problem continues to go on. The most remarkable par about it all is if you use the Mail app on an iOS device it deals handles the ics files perfectly! If you have this problem please acknowledge it on this forum, with enough support Apple may actually do something about it.

Apple support, is anyone able to assist in this case, seems not to be a fix???? very frustrating , please help

After reading this entire thread and trying all of the potential resolutions, I have come to several conclusions. First, there are actually several problems posted here that appear the same but are not and thus there are several 'fixes' that work for some people and not others. Here's the list of different problems I saw in the thread:

1. Microsoft products are installed and the default app was changed to the CalendarFileHandler. Change it back to the Calendar app.

2. The ical appointment being sent is not in compliance with standards or is out of date (std version 1). look at who's sending it and from what type of server/application.

3. Characters in the meeting location like a "-". I haven't tested this but suspect there is a different reason the "fix" of removing the "-" works.

4. My problem with an ical appointment relates to the original meeting being modified (canceled the original and a new appointment date/time being sent in one ical). The email showed the changed appointment but the ical processing only removed the old one and never added the new date and time.

Therefore, it appeared to process but in fact it never ADDED the new appointment date and time. I'm still looking for the reason for this and have not seen any resolutions here that explain it. It could be user error on the sending side.

My point is this...don't assume these are all related to the same root cause problem because they are not. I hope this helps and saves someone time.

OMG!!

What a hack.

Thank you Lonnie, I was desperate.

And as always Apple support *****

I have yet to find a single .ics file that can be successfully imported into the Calendar app on El Capitan 10.11.6 (or any prior version for the last 5 years). Perhaps it is fundamentally broken if the user is not using iCloud, i.e., the calendar is local to the machine.

In the current case, there is a local Mac OS X Server App Calendar Server. This also does not work. It never worked before even when there was no server.

Here is an example file that does work:
