Currently Being ModeratedDec 11, 2010 10:23 PM (in response to Mike Janowski)More info from investigation. Snow Leopard iCal v 4.0.4; Tiger iCal version 2.0.5.
Went to iCal help on both machine/versions. Interesting. v2.x help is pretty minimal; v4.x has a tantalizing clue regarding the "Export" or backup procedures, in that the resulting file in v4.x is called an "iCal Archive"...and even though exporting and/or backing up (what IS the difference, anyway?) creates a file with the same extension, I'll bet the actual file is different enough so that v4 has trouble reading v2.
I've been working on this now for four hours. This is ridiculous! This is supposed to be a program that Mr. and Mrs. Amerika can use without thinking, yet it's this difficult to copy your calendar to your new, updated computer? So tell me again why I should upgrade, Steve Jobs?G5 dual 2 (4g)/Intel 2.6 (10 gig))/iMac 3.06 (8 gig), Mac OS X (10.6.5), older slower Macs
Currently Being ModeratedDec 11, 2010 11:09 PM (in response to Mike Janowski)AND NOW, THE SOLUTION! And it's even more arcane than you can imagine!
After posting I continued to do research, searching for any info about problems moving iCal v2 calendars to iCal v4. Lo and behold, someone had exactly the same problem! You'll never guess the solution (NOTE: do the following procedure on a COPY of the iCal folder...always leave the original untouched.)
-inside User/Library/Application Support/iCal is a folder called "sources". In the Sources folder are a bunch of alphanumerically-named folders...these hold the data, etc., for each calendar in your iCal. Opening any one of the funky-named foldersthree files: a .plist, one named "Corestorage.ics", and an index file. Opening the info.plist file in TextEdit, you'll see a string containing the name of the calendar. Open the .ics file with TextEdit, and you'll see a text representation of all your calendar entries. Do a Command-F (Find), and search for the text string "X-WR-OCCTRIGGER". Delete it, and save the file. Move the edited iCal folder to the same position (User/Library/Application Support) on the new Snow Leopard computer. Double-click on the edited .ics folder, and it will import into iCal and display properly. For WHATEVER REASON, eliminating this string allows calendars created in v2 to display correctly in v4. Crazy. Thanks, iCal development team!G5 dual 2 (4g)/Intel 2.6 (10 gig))/iBook 1ghz (1 g), Mac OS X (10.4.11), older slower Macs
Currently Being ModeratedDec 20, 2010 4:56 AM (in response to Mike Janowski)Thanks for posting this solution, Mike! This was a HUGE timesaver and headache reliever for us. I had over two years worth of data in iCal on Tiger. Thanks to your post (which was far better than the help Apple was providing over the phone), I had all of our iCal data back in place in less than half an hour! Any Tiger user going to Snow Leopard that used iCal needs this info. IT WORKS! Deleting the "X-WR-OUTRIGGER" text string did the job.
I just can't believe that Apple did such a terrible job of communicating this obvious glitch. For those of us who actually use iCal to keep track of very important events, Apple should have published this as a warning/solution to Tiger users BEFORE they upgrade to Snow Leopard.
Thank God there are people like you out there that figure out things like this and take the time to let others know about it. Kudos to you, Mike!

Currently Being ModeratedDec 20, 2010 8:47 AM (in response to Go Rangers)Thanks. As I mentioned, the only way I found the solution was through research on the boards. Here, because they deserve the real credit, is the post where I found the solution. Mark them "solved" so they get a star...

Currently Being ModeratedMar 8, 2011 9:08 AM (in response to Mike Janowski)ok...can anyone please here write a quick step by step to tranfer Tiger iCal to Snow Leopard iCal? All this talk about file extensions is fine but there's little operational info for us less technical savvy...macbook, Mac OS X (10.4.11)

Fab stuff - worked for me too!

Hey, throw me a "solved"!!! I think some of the big hitters on these boards think I'm nothing but a whining malingerer!
Currently Being ModeratedJun 12, 2012 3:01 PM (in response to Mike Janowski)
No option I can find for me to mark solved - this is your post isn't it?
Currently Being ModeratedJun 12, 2012 3:14 PM (in response to Gregster)
Yup...you don't see a green talk bubble with a checkmark in my post with the solution?
Currently Being ModeratedJun 12, 2012 3:28 PM (in response to Gregster)
OK, no biggie. thanks for the complement. This stuff is so bewildering sometimes, it's nice to know I helped someone.
