i am not able to download and install mavericks from the app store
hello
i have a macbook pro with mac os x 10.7.5.
i am trying to download and install mavericks, but when i press the "install app" it just thinks for a sec and then doesn't do anything.
is there a way to reinstall the app store or do a rerun to the 10.7.5 so it works or something?
thanks
Mac Pro, Mac OS X (10.7.5)
