I have a MacBook Pro running a 2.66Ghz processor with 4GB of Memory.

 

Since upgrading to Version 10.8.2 I have been having icalexternalsync issues--don't even know what that means.

 

My computer gets hot, starts overworking and in the Activity Monitor I noticed that is was taking up over 100% of the %CPU.

 

This has basically rendered my computer useless. The way I have survived is by having my Activity Monitor opened and Force Quit the icalexternalsync every few min. But if I forget...it takes forever!

 

Anyone capable of helping? I am a complete novice, so please write in a way that someone as dumb as I am can understand.

 

Thanks,

 

YK

 

P.S. I LOVED my computer before this. It was fast and easy to use. It was SO MUCH BETTER than my Dell. Now I'm thinking of going back.

    I too have been seeing this... it's frustrating that this occurs!... I run a trading program through Parallels and I have either iCalExternalSync or CalendarAgent or BOTH taking over and consuming the processor.

     

    This is unacceptable!

     

    It is not a critical process that it should been commandeering my computer. Killing the process does no good ~ it just reaapears. 

     

    I have to shut everything down and re-boot. What a waste of time!

     

    Apple, please, allow us, your customers, to have the an option of some sort to pause these processes.

    Am having the same issue on a 13" MacBook Air (mid 2011) with 4 gb of memory running 10.8.2.  Am using Office 2011 as my main productivity tool, although with this problem I am unable to use Outlook at all. Completely frustrated.  My computer is not usable in this condition!  Any ideas would be appreciated.

    thomasfromberkeley... What worked for me was I deleted all unnecessary calendars and I then exported the ones I wanted to keep, each one individually, as a back up. I also turned off "notifications" and "iCloud"... I just turned on "notifications" and "iCloud" back on and will see what happens...

    Hi Rick.  Did you have replicating calendar events as well?  I've got them (mostly for all day events) and old notifications keep reappearing by the hundreds.  Will give your solution a try, after the days work is done.  Many thanks!

    1) quit calendar

    2) wait for it to sync and really quit

    3) go into terminal and type 'rm ~/Library/Calendars/Calendar\ Cache' then 'rm ~/Library/Calendars/Calendar\ Sync\ Changes'

    4) restart calendar and wait for it to sync back to your servers

     

    let me know if that does it.

    Am having the same issue on a 17" MacBook Pro with 8 gb of memory running 10.8.3.  I believe this issue started when I began using BusyCal instead of iCal.  It's a much better tool, but this problem -- the entire system getting unusably slow every 15m and even hanging for 20s at a time -- is untenable.  Quitting iCalExternalSync via the ActivityMonitor (which shows it is consuming much of the CPU and 3GB+ of RAM) does the trick, but I can't do this every 15 minutes.

     

    I tried lithboy's solution to no avail.  Any other proposed fixes for this problem?  Thanks!

    I am seeing the same issue. Interestingly only on my wifes account on a MacBook with MacOS 10.8.4. My account is working fine and we are both using the same setup in iCal. Calendars are connected to my iCloud account running our family calendar. I also can't really think of any change that may have triggered this behaviour. Also tried lithboy's suggestion but didn't change anything.

    This is what I heard back from an inquiry to BusyCal:

     

    Hi Nolan,


    Yes, iCalExternalSync is very buggy. It's also known as Sync Services and is deprecated in Mountain Lion and will be completely removed from Mavericks.


    In BusyCal, you can disable syncing with Sync Services in BusyCal > Preferences > Advanced, which should clear up the problem.

     

    Since I want to preserve syncing with FB, Google Calendar, etc., I uninstalled BusyCal, and the problem stopped immediately.  Waiting for Mavericks to reinstall BusyCal...
