caneflyer Level 1 Level 1

Since the Lion upgrade certain events are appearing and disappearing at irregular times in iCal on the Mac, even though they are always visible on my iPhone and on the web via MobileMe.  These are only events that I received invitations to. Any event I created myself is always present.  Any thoughts on a resolution?

MacBook Pro, Mac OS X (10.7)

    Same for me.  An invite comes in via email.  It appears for a second in iCal and then dissappears, only to reappear some time later.  Also, when I directly click the .ics attachement in the email, the invite briefly shows up in iCal and then dissappears.  Really frustrating!

    Pleased to hear I'm not the only one.  I have MobileMe support trying to help me with this, but no resolution yet.

  • Elliot5677765 Level 1 Level 1

    I actually don't use MobileMe at all.  I closed the account and have transitioned to Google Apps - so I do believe this is an issue with iCal and perhaps Mail 5.0.  Regarding the issue, I have noticed that once I refresh the calendar manually by going to iCal > Calendar > Refresh All, the invite appears again most of the time.  Just very odd that clicking the actual invite .ics attachement in Mail 5.0 causes the invite to appear in iCal for a second, then dissappear.

    Elliot, do you use Bento?  I just had Bento crash on me while adding an ics invitation to iCal, and was wondering if there might be a connection.

    I am Having the Same Issue. Even when I set invitees and I am the creator, the event disappears. It really isn't consitant either. It appears and reappears. I can still view it on my iPhone. Very Frusterating!!!!


    This started happening when I upgraded to Lion

  • paulnptld Level 1 Level 1

    Intalled Lion.  Same issue for me as well.  I click on the invite in Mail, and within seconds it vanishes from iCal. 


    Just found that killing iCal and relaunching it allows it to accept the invitation.  Not sure if this will continue.

    I just discovered the same issue, my iCal syncs with Google Apps, and the invitation shows up with a grey dot, the top shows 'Updating' and it dissapears, i found the only way was go offline(pull out ethernet), double click, accept the invite then go online again.

    it then updated and the event remained in my list.


    pretty serious bug?


    thanks to a quick google search i found this post so i know im not the only one (shared pain)

  • Ronald Robson Level 1 Level 1

    Same issue here but this was going on in Snow Leopard as well. I was hoping that Lion would resolve it. I use Google Apps, not Mobile Me.

  • Dave310 Level 1 Level 1

    Not 100% related to this post, but I can't find a similar one anywhere else.  I'm accepting the ICS invitation via the mail client on my iPhone.  The event then shows up in Google Calendar, but then less than a minute later it disappears.  This just keeps happening over and over again.  Does anyone have any suggestions for things I can try?

  • erickgrau Level 1 Level 1

    I have a client with a similar issue.  She has iCloud (mobile me) account used ONLY for email really.  Her Claendar and Contacts are stored on MS Exchange accounts.  On iOS, no issues.  On her Mac, when she receives an invite to her account, she wants to accept it and store on her Exchange account using iCal.  She clicks 'accept', it opens iCal, and the even dissappears.  Sometimes they come back on there own.  No issues on the iOS device accepting and saving on different account.


    Anyone get an answer from Apple?



  • caneflyer Level 1 Level 1

    Not for me, anyway.  MobileMe support eventually gave up after working with me for a few weeks on the issue.  They couldn't solve it.

    Hdware Mac mini Server Mid 2010

    Processor  2.66 GHz Intel Core 2 Duo

    Memory  8 GB 1067 MHz DDR3

    Software  Mac OS X Lion 10.7.2 (11C74) - iCal Version 5.0.1 (1547.4)

    Talking to: Exchange 2010, gmail calendars.  No MobileMe or Google Apps sync at the moment (although I have tested both w/ similar results).


    I'll be submitting bug report w/ log data as well.  I figure though the more this is posted, the better.  This bug makes working in iCal quickly and efficiently all but impossible.  Takes me an average 10 - 15 minutes to babysit it through an update of 3 events.  Not practical for work.

    Same here. Lion 1.7.3. iCal Version 5.0.2 (1571)Click on invite, it shows in iCal then disappears. Does anyone from Apple actually review the forums?


    The workaround is to quit iCal, click on the invite which brings up the event in iCal, then Accept or Decline. One painful thing about this, at least for me, is that the event doesn't show in the "inbox" in the upper left. It just shows in the right slot with a gray circle to the left. You need to know where it's going to show - easy to miss in the Monthly view.


    Weird thing to slip through QA. I haven't been blown away by Lion's "stability". Feels a little less baked than Snow Leopard.

    Yeap - same issue for me. Hope Apple resolve this soon otherwise I will just have to stick with usiing Google Calendar rather than iCal.
