Fixing “iTunes was unable to load dataclass” Error

I’ve been dealing with the “iTunes was unable to load dataclass” for several hours.
I’ve uninstalled iTunes, Xcode, deleted the Mobile Device Support… reinstalled everything, booted the system, and nothing seemed to work.

After searching for quite some time, i’ve found this post. Long short story, if you delete this framework:

/System/Library/PrivateFrameworks/MobileDevice.framework

…and right afterwards you relaunch Xcode (which will, as a result, reinstall such framework)… you should be able to get rid of this… annoooooooooying problem.

 

Unlock Hidden Wallpapers in MountainLion

Long time no see!. It must been a month, at least, since my last post. I’ve come across this article… and thought it would be a good idea to store this somewhere, so i don’t loose track.

It’s simple. Just open this folder:

[code]/System/Library/Frameworks/ScreenSaver.Framework/Versions/A/Resources/Default Collections/[/code]

You’ll find about 147 MB of high definition wallpapers, that are already bundled in your Mac, and nobody told you. They’re retina-sized (3200×3000), so if you’re using a Macbook Pro with Retina Display.. it will definitely look awesome.

OSX Lion: Refresh Launchpad Contents

I recently came across a problem. The contents of the launchpad, somehow, got corrupt. I was seeing files that shouldn’t be there. So… how did i fix it?

Open this folder:

~/Library/Application Support/Dock

(CMD + Shift + G… and paste that!). Once you’re right there… you’ll need to delete delete the “.db” file. Last step… relaunch the dock!

killall Dock

That’s it!
