I had a HD failure and have replaced the HD on my iMac and I have been able to restore it apart from a number of things such as emails. How can I restore my emails (Mac Mail) and a number of programmes such as Apeture. Another thing that is causing me issues is that in iPhoto a number of thumb nail pictures are not visible unless I double click them. I tried restarting iPhoto holding down command and alt and choosing to rstore them, but it didn't work. My Mac is now running Snow Leopard but I had recently upgraded to OSX Lion. Is there a way I can get back to Mountain Lion and how would I do this? Thanks.
