xcode iconUsers looking to install the free Xcode 4.1 developer tools for OS X Lion released last month have been running into an issue that has caused difficulties with the installation process. During the installation process, users are prompted to quit iTunes if it is running, but the alert does not disappear even after iTunes has been quit and the installation remains stalled.

In Apple's support document on the issue, the company notes that users also need to quit the iTunesHelper process, which can be found in and exited from the Activity Monitor utility. Once iTunesHelper has been quit, the installation proceeds normally.

Apple today addressed that confusing behavior with the release of Xcode 4.1.1 through the Mac App Store, a small delta update that removes the installation alert that has been causing problems for users. Users who have already successfully installed Xcode 4.1 do not need to install the updated version.

What's New in Version 4.1.1

This is a delta update to Install Xcode.app that fixes the "Installation Alert" to quit iTunes. You do not need to re-run the installer if you already have Xcode 4.1 for Lion successfully installed, as the included tools are unchanged in this update.

Xcode 4.1.1 remains a free download in the Mac App Store, but does require OS X Lion.

Tried again, it still said 3.17 GB but it only took a minute. Guess they just don't show the overall size of the delta.

I knew it was unnecessary, but I decided to grab the upgrade anyway just to get rid of the notification, since it was small... except it started to download 3.17 GB worth. Not exactly small. Are the delta updates not working yet?
No, it was a delta update. Are you sure you hadn't deleted the installer previously? It would redownload the entire thing if you had.

Delta Updates? Xcode? You are a funny guy.
Actually, Xcode should be coming in delta updates from now on. Apple mentioned at WWDC that Xcode 4.1 would be divided up into packages to reduce download size of updates, and if you check in the Install Xcode.app bundle, that's exactly what they did. It isn't perfect, but it seems we won't have to download the entire thing over again.

Hmm, I just noticed there's a package labeled "iPhoneSimulatorSDK4_3Patch1.pkg". That may mean that you won't even have to re-download entire packages in the future. I take it back. It seems like they did it perfectly! :D
