my son's macbook seems to clash with my IMac. He recently deleted my bookmarks on his macbook. how do I avoid this?
My son was logged in on his macbook and managed to somehow delete all my bookmarks, his mum's bookmarks and replace them with his own bookmarks. How do I stop him from doing that. We share the same WiFi network. Now I have lost everything. Any ideas on how to recover them?
iMac, Mac OS X (10.7.4)
