ICAL seems to be in a loop. I cannot add a new appointment; I get the message displayed at the top of the screen "updating" My Iphone 5s and my MacBook Air are syncing. All 3 devices are on iCloud.

Question

ICal is frozen, cannot post new appointments.  I can post appts on Mac Air and Iphone 5s...they are syncing thru Icloud but the MacBook Pro is stuck.  I get  the message updating...that has been going for several hours.  How can I reset ICal?  I have already forece-quit, shut down, and closed...none seem to clear the problem.

When you next have the problem, note the exact time: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode, or until they start to repeat. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
