Hi. So, I'm running on a Macbook. It is 10.7.5 (lion) but it says something about the graphics card? How could I bootcamp it or update it? How far can the update go? I tried 10.9 but they don't sell that update anymore. I am so confused and lost. I just wanted to know if any of you fellow simmers could help. It plays The Sims 3 just fine. Is there a graphics settings I could look on. It is also a EARLY 2008 model of a MacBook. I just got it and I love it dearly but I'm tired of playing just The Sims 3. I played The Sims 4 on my mom's laptop and it worked just fine. I don't know her graphics thing nor do I know how to tell on hers. Hers is a Windows 8 laptop. I just got my MacBook about 2 days ago but it still don't wanna launch The Sims 4. I am hoping this can be fixed. Plus one more question, what is boot camping and can I have links for that and a link for the latest update my MacBook can have please? Thank you all in advance. -LynzSimmer
