My parents have an older Mac mini 1.8 C2D running leopard 10.5.8 they only browse the web and check email overall the computer has become very slow they have a hard time understanding the concept of closing apps. What concerns me is they will no longer be receiving updates from apple and never close chrome for it to update. Would Linux be better for them such as Zorin or Ubuntu in terms of speed and security. (They do bank and buy online often) or would I be better off getting them on Lion or snow leopard though the resume feature would be a nightmare since they never close any app and seldom restart. Thanks for any help!
