I was downloading the latest iOS SDK from the Mac App Store and initially I could not find the download status. Eventually I found one way to do so, go to the “Purchased” section of the app store and you should be able to view the download progress!
I realize it is pretty obvious once you see it, but I really wish Apple would put the progress someplace else too… if anybody has other tips for viewing DL status, please post. Thanks!

Thank’s
You are my savior
many thanks
