http://support.apple.com/kb/HT4818?viewlocale=en_US&locale=en_US#2 I have not upgraded from Snow Leopard as of yet as I need to upgrade to Office 2011, and replace several other PPC only apps. However the article above states that Windows XP is not supported in ML is this true? I have a XP partition and I need it for Windows apps. Do not tell me that I also need to upgrade that as well? I have 4GB's of RAM, and have portioned the Windows NTFS drive for 80GB of which I have more than 60GB's free. Will this be enough?
