Maybe I'm going senile, but did there not used to be an App Store app through which I could acquire new apps and check updates on old ones? It was, if I recall, in my Utilities Group? Well, it has gone awol and I have no recollection of deleting it. Indeed, I have Delete Apps prohibited through Settings so I can't have deleted it in error. How can I get it back? I have just upgraded from Snow Leopard to Mavericks on my iMac - is this perhaps a "feature" where I now have to do all updates, etc. via the App Store application on there? If so, Apple,that's a nuisance as I spend more time away from the iMac and with the iPad than vice versa. Any advice for a confused old man, please?
