I am trying to install Mavericks on my 2009 Macbook Pro running OS 10.7.5.

When I click on Install App in the App Store, Mavericks doesn't install. Either nothing happens, or a spinner briefly appears at the top and then disappears.

An I doing something wrong here? I've never used the App Store before, so maybe there's something I'm missing. The first time I was prompted for my Apple password, which I put in.

Here's a video I made of what happens.


I solved this issue by doing the following

  • Turn on the Debug Menu in the App Store using

    defaults write com.apple.appstore ShowDebugMenu -bool true
  • Using the Debug Menu, clear cookies and reset the application

  • Open the Downloads directory and delete the com.apple.appstore folder

  • Quit the App Store and kill the storeagent process

  • Try to install again

I had to do the above steps a couple times before I got it to work.
