Today I was updating my Mavericks installation and during the process it seems that App Store somehow "hung up" on installation and some downloads didn’t download properly.
Because of that, now I see multiple instances of "OSX Update 10.9.1" in updates history, and not just that, but every other part from that chunk of updates such as iTunes update.
When the download finally "finished" and when I activated it, it said that it was corrupted and it should be downloaded again. I did that, activated it and everything went OK, update is now here.
I’m interested if these types of situations are common and are not something to worry about. From my previous experiences, App Store is kind of wonky so this behavior is not unexpected, but I see this first time and I’m little concerned.
