software update com.apple.WebKit.WebContent: Error ITSExceptionHandler

Hi,

My software update does not turn up any OS X updates. When I do a software update, app store shows no updates are found, and in the console I can see the following messages:

com.apple.WebKit.WebContent[532]: ERROR: ITSExceptionHandler: {message:"TypeError: 'null' is not an object (evaluating 'document.querySelector("#header").removeClassName')", url:"https://se.itunes.apple.com/htmlResources/F3F8/da-storefront-autoinstallations.j s", lineNumber:"358"}

This has been happening since 10.9.5 update, which it did not find, I had to download and install it manually. I only notice the error today.

Anyone has similar problem?

Thanks

MacBook Air, OS X Mavericks (10.9.5)

Wise or not, it's not available from Software Update. If that's what you were expecting, you haven't demonstrated a problem.

Why you sounds as if you are the one who decide it's available or not.

How you do know if you are not having the same problem?

As I said earlier, my other laptop has that update show up.

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.

If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.

There are ways to back up a computer that isn't fully functional. Ask if you need guidance.

If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.

*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.
