known issue of xcode4 MAS purchases, A horrifieng number of the ( german ) reviews say there are issues in never completing the setup or to stall at some percentage.
To resolve : Open the downloaded package by right-cliking "show package contents", then run the installer from there, shall fix the issue for most people.
I have the exact same issue. Xcode download hangs at exactly 269.57 MB. When I check /Application Support/App Store it seems like an generic installer .pkg has been downloaded and then the download has stalled.
This has been happening for a few days, over multiple attempts. Tried changing DNS setting as per some other posts but makes no difference.
A fix for “An error occurred”
*Note Temp files are located at: ~/Library/Application Support/AppStore/
To fix the “An Error has occurred” perform the following:
1. Sign out of the Mac App Store (Store Menu -> Sign Out)
2. Quit the Mac App Store app
3. Delete anything underneath ~/Library/Application Support/AppStore/
4. Restart the Mac App Store app
5. Sign into the Mac App Store (Store Menu -> Sign In)
After signing back in, you should see your downloads start over.
It also would seem there is a debug menu you can do a safer alternative:
1. Open Terminal
defaults write com.apple.appstore ShowDebugMenu -bool true
3. Relaunch the AppStore
4. Choose the menu item Debug Menu -> Reset App
5. Choose the menu item Debug Menu -> Check for Available Downloads…
I can't even start the download... After a while I discovered that the whole package is available without the downloader app throug this link:
When you log in, you will have a menu on the right side. Go to "Developer Tools" and you will find it (around) the fourth item in the list of tools to download. It says version 4.1, i am not sure if this means 4.1.1 or not.
Just if you want an alternative solution.
EDIT: Oh, this version seems to be the one without the delta update for the iTunes error message.
I've been downloading Xcode from the app store since the 7th of Sep. As of 30min ago I had downloaded 2.51GB of 3.17GB. Sudnly it stops and the following error screen apeares.
The application could not be downloaded
The server gave an error during download: 403
when I click re-try the box just re-appears and I can't begin the Install from the app store any more.
