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.
