Hello, I'm planning to buy an external USB DVD for my macbook (A1181). My DVD rom broke so I'm wondering if it's possible to use an external USB DVD instead of getting it fixed? I have a feeling it will cost a lot more if I get it fixed or bring it to a repairer. I found some around but they only state "macbook air/pro" so I'm not sure if they'll work on my macbook unibody white 13". Please help, thanks! I'm wondering if any of these would work: Ex1, Ex2, Ex3 And another question, I currently have Leopard 10.5.8 and am planning to upgrade it to 10.6. Of course, I need the DVD and install it. However, will it work on these external DVD? Will I have any problem? Please help, thank you so much!!
