So I got the Core i5 Mac Mini in August of last year. Been a good computer, but I am having some issues with Lion. My Hamachi/Logmein VPN server doesn't work with it as do a few other programs. In an attempt to downgrade to Snow Leopard by inserting my retail Snow Leopard disk into an external DVD drive, it kernel panics. A genius said due to firmware I can't downgrade?
