Apple based programs will not open after os X Mavericks update

As mentioned I updated to Mavericks, biggest mistake. None of my apple made programs will run (app store, preview, calendar).

Does anyone know how to solve this? I cant find any info on it

Cheers

Do they just fail to launch or crash?

Can you do a Get Info on some of the programs and tell us their version numbers?

Since those programs come with Mavericks, there is something very wrong as all those run just fine on Mavericks. You are not by chance trying to run older versions of those applications on another install of OSX are you? Are you launching the apps that are installed in Mavericks?

That was my thought as well Dennis. Without knowing more about exactly what happens it's hard to say what's at the door of the problem.

Apple programs won't open WebCore Plug-in warning

I downloaded Mavericks two days ago, everything was fine then this evening when I tried to open any of the Apple products like Safari (currently using Firefox), App Store (to check for updates), dictionary, mail, ibooks, itunes etc. I get the yellow waring boxes saying that

'Safari quit unexpectedly while using the WebCore plug-in'

ibooks was and itunes did actually open but when I clicked on istore in itunes or a book in the ibooks, the same warning appeared and quit the program.

Any help would be appreciated, and I'm not very technically minded.

Thanks

Open Safari, click on Preferences, then click on the "Extensions" tab. Now, disable the extension called "WebCore" by clicking on it in the left side of the dialog. Once it's highlighted, go to the right and select "uninstall". After it finishes, restart Safari.

You should be OK once that extension has been removed. It's not compatible with Mavericks is why you're getting the error.

Thanks chscag, everything is fine now, I don't know where the Webcore extention came from.

It's part of WebKit and used in any WebKit based application (any application that taps into OS X's libraries for displaying web content). Thus, it's not something that you would have installed consciously nor is it something that you could have avoided.

From the sounds of it, some extension was acting a little wonky. Glad everything is solved.
