For some reason Xcode updates are shown in Launchpad (both the dock icon and if you can manage to find the app in Launchpad itself) and then sync&#x27;d back to the App Store after some delay. The delay seems to be completely random.<p>I think for some class of updates that includes Xcode and OS the App Store uses a separate tool to download and run the update so it has to use some sort of (very) delayed IPC mechanism. Regular apps update through the App Store itself so it shows progress immediately.
