how to delete the app store updates?
For example, i don't need digital raw compatibility software nor the updates which take up storage space.
how can i delete this app (RAW), or just delete the updates?
MacBook Air, OS X Mavericks (10.9.1)
To hide an OS X update, you just have to right-click the update and hide the update. That's all.
I recommend you to install all updates, because all of them are designed to improve performance and compatibility. There are exceptions, like the RAW updates (which add compatibility for new cameras), but respecting to all other updates, you should install all of them.
You cannot hide updates for apps purchased from the Mac App Store
