Im looking to install SL 10.6.3 or 10.6.8. I have a dell d620 with nvidia card n 2gb of ram running windows 7. I searched n read mix reviews on whether an external monitor would work, it seems it onky works on 10.6 n not on 10.7 or only certain video cards in 10.6, correct? Also once installed, will the ethernet port still work for wired connection or only wireless will be avaliable? Thanks and appreciate the help!
