I have Macbook Pro late 2011 which came with Lion. I installed Mountain Lion a few months ago and it worked great. Then my HD became damaged I just installed a new HD and command r brought it to Lion, which I loaded. I want Mountain Lion again - I can't find it to reload it. It must be in my app purchases or something. Can someone indicate exactly where to find it? Thanks. I have other questions about the HD restore in another thread I still need answered. Thank you.
