I upgraded an old MacBook Pro to Mavericks, and I am now trying to download Xcode.
In App Store I searched for "xcode", found it, clicked "Install".
It is now saying "INSTALLING", but nothing happens, CPU at 0%.
If I let the computer unattended, it falls asleep (disk stops).
While waiting I tried to install MacPorts, but it says
Waiting for other installations to complete..., so the installation is still going on somehow.
What should I do? Restarting App Store and does not fix the problem.
I rebooted and re-clicked INSTALL, and still the same problem.
It is a bit similar to this question but I have no
/Library/Preferences/com.apple.SoftwareUpdate* file to delete.
