A couple days ago I tried to download Xcode from the mac app store. About 1/3 of the way through, I put my computer to sleep, forgetting that I was in the process of downloading it. Now, the download is stuck and I have tried to go back into the mac app store and install it again, but I can't get the download to start back up again. Is there a way to clear it so I can just download it over again? Any help is appreciated, thanks!
