    Thanks, renny27.

    this simple step ( changing the 'Calendars' folder to '_Calendars')  seems to have made all the difference for me too...

    It took a few minutes for the calendars to rebuild ( I sync and or subscribe to 12 different sources) but all seems stable now.

    Dear all,

    I hope Apple with fix this bug on the next version of iCal.

    iCal Version 5.0.1 (1547.4) is bugged!

    iCal crash in Lion (EXC_BAD_ACCESS) when there is more than one CalDAV accounts (2 Google calendar accounts). If you've 2 accounts, when you start iCal, just after the update/sync, iCal crash.

    Now if you disconnect one calendar, these crahes do not exist.

    If one guy can help me to better bypass this bug, will be great.

    I agree–there is a bug with this version of iCal. My iCal crashes on launch repeatedly until eventually staying open.


    I tried every trick in the book–totally wiped out all my iCal user data and re-created each of my calendars one by one. iCal was stable again until I added a Google account with delegated calendars; then it started crashing again. I agree, it's tied to CalDav and possibly delegation.


    Please fix this bug in the 10.7.3 release!

    Anybody still having problems after the 10.7.3 update? I'm not, not anymore! I think somebody mentioned something about purchasing 'BusyCal', while BusyCal seems to be a great program, I would much rather stick to iCal and not spend extra money on a third party app. iCal is working great now, I have multiple Google calendars and subscriptions. Everything is in working order and most importantly, NO MORE CRASHES!

    I've gone through these steps quite a few times, and iCal still crashes. I have some other issues with other apps, so Apple Support, here I go.

    Last week i completely reinstalled 10.7.5 on an OWC SSD. All very well and speedy. Have been a mobileme/iCloud member from day one, never had any issues.


    But just the other day suddenly my iCal broke. I tried all of the above: all the caches, the prefs, no internet, i even swapped the app. Nothing. My iCal is dead and crashes every single time: EXC_CRASH (SIGABRT)


    So Very Annoying, Apple!


    After spending several hours with it i'm done and now i use the online iCloud version. Sadly, Busycal is not for me, i'm on a Mac Pro 1,1 and 10.7 is my limit.


    I did however reboot my previous OS and iCal was still doing fine on that. So this is definitely a corruption in my user account.


    Anyone? I'd like to get this fixed somehow...this is not supposed to happen on a native OSX application.

    Hello MadisonP,

    I know I'm 2+ years behind. Just installed Lion, the latest one I can install. Now ical won't work. Says it's upgrading but never finishes, must force quit. I saw your solution, sorry but dont' know how to get to home> library etc.  Did n't there used to be a library folder with cache etc. Where is that in finder now.


    I will upgrade this year but for now, I use ical all day every day for my business.
