Suddenly getting duplicate characters when entering / editing an event. How do I download a "fresh" version of iCal?

Hello! Just to get this clear: do you have this ONLY in iCal/Calendar? Not in any other apps? And does it occur only when creating an event, or does it happen anywhere in iCal/Calendar?

btw: there is no way of downloading a fresh iCal, other than reinstalling the entire OS X, or deleting all files and folders that relate to iCal/Calendar in your current install of OS X.

it might prove easier to solve your keystroke problem than doing all that.

I'm guessing you really mean Calendar.app, right? Is it only in Calendar that you are getting repeating characters? Did you recently spill anything on the keyboard? Do you have another keyboard you could try to see if also has the problem? What kind of keyboard is it (make & model)? If it's a third party keyboard is there separate software that needs updating to go along with your Yosemite update? Maybe try giving it a good cleaning with a can of compressed air and blow out any small particles that might have fallen in between the keys? Is it one of the newer membrane type keyboards or one of the old-style with real keys?

Anyway could you try this in a terminal window:

cd /Applications/Calendar.app/Contents

ls -la *

sum MacOS/Calendar

On my Yosemite system (10.10.1) I get for the checksum

44982 3435 MacOS/Calendar

What do you get? from both the above commands?

Also what do you have your key repeat rate set at right now? Look in the Keyboard System Preferences panel and it's located in the top left part of the pane.

Look at the key repeat rate - set to the slowest (leftmost of the slider) - does this have any effect on the problem? Are you a reasonably fast typist or a hunt-and-peck type?

Terminal is in /Applications/Utilities

Do you know how to copy/paste stuff on Mac? like the above commands (copy them by highlighting and then Command+C - then paste them with Command+V in the Terminal window)

Also what is the "Delay until repeat" parameter set to? try putting it on "long" -- any different behavior with either of these two keyboard settings?

Yes, Calendar.app. Only in Calendar. Nothing spill don keyboard, I'm using it now to type this message.

Do you know how I force a download of the complete OS and apps?

Thanks

Rather than that, go to "Apple menu > System Preferences > Internet Accounts" and for all accounts listed there, disable Calendar syncing except for 1 account (preferably the one you're noticing the issue occuring)

With only 1 account syncing calendars, does the issue still occur? Please make a back-up before starting, preferably with Time Machine: Basiskenmerken van de Mac: Time Machine maakt een reservekopie van een Mac - Apple Support

I have been randomly having this same problem over the past few months! I say randomly as it is an intermittent issue--doesn't happen ALL the time. It is NOT taken care of by restarting or even reinstalling iCal. I have just this week had my entire iMac wiped and OSX Yosemite reinstalled at the Genius Bar and I STILL have the problem with the characters randomly duplicating themselves. It is NOT the keyboard as I have tried different keyboards and all of them act the same.

Firechief2900, did you ever find a solution to this issue?

I am having the same problem. And before anyone starts recommending all the same solutions, it is isolated ONLY to using the Calendar app in Yosemite v. 10.10.2. I am using the same keyboard and computer (without any restart) to post this now. Any suggestions?

I have the same problem. Only in Calendar, keys duplicate. It started about a week ago. It's "rreeaallyy aannnnooyyiinngg!!"

I just updated to OS X Yosemite Version 10.10.2 yesterday and now I'm getting the double character entry as described by other posters above. The problem on occurs in my Calendar and only occurs when typing in the "Event" field. It happens hen creating a new event or edited an existing event. This doesn't happen consistently but once it begins double entering characters, backspacing and retyping doesn't fix the problem. The event text always seems to be ok for the first few lines and the double characters start appearing in the third line of text and continues.

I too have been having this same issue for a couple of weeks under the same conditions mentioned by others. My only way around it is to first enter the intended text in TextEdit and then copy it to a Calendar entry.
